Ryan Dwyer f7aed5c7e5 Fix containers not being resized when entering scratchpad
This fixes a regression introduced by
662466e8db. When adding a container to the
scratchpad, setting container->scratchpad = true before
container_set_floating made container_set_floating believe that the
container was already floating. This fixes it by setting the property
afterwards instead.

Franklin "Snaipe" Mathieu 8fc9328334 xwayland: populate window_properties in json for views
window_properties is documented to contain a subset of the X11 properties
of a window (its title, class, instance, role, and transient ID). This
commit adds the missing json object from the get_tree output for
xwayland windows only.

This is a follow-up of #2911.

Ryan Dwyer 662466e8db Fix crash when resizing container hidden in the scratchpad
Firstly, the container was wrongly identifying as a tiling container
because it had no workspace.

Secondly, when calculating the maximum possible size we can't use the
workspace if it's not there, so we'll allow unlimited size in this case.

Ryan Dwyer 6deb726873 Fix crash when quitting a QT app on the wayland backend using menu
QT unmaps the view before destroying the popup. We destroyed the popup
in response to the view unmapping, but then we'd attempt to destroy it a
second time which caused a crash.

The patch removes the listener.

I tested it with GTK as well, and can confirm the popup is still being
destroyed.

Merge pull request #2870 from RyanDwyer/refactor-input-manager
Minor refactor of input manager
2018-10-20 08:42:56 +02:00
Ryan Dwyer c006717910 Minor refactor of input manager
The input manager is a singleton object. Passing the sway_input_manager
argument to each of its functions is unnecessary, while removing the
argument makes it obvious to the caller that it's a singleton. This
patch removes the argument and makes the input manager use server.input
instead.

On a similar note:

* sway_input_manager.server is removed in favour of using the server
global.
* seat.input is removed because it can get it from server.input.

Due to a circular dependency, creating seat0 is now done directly in
server_init rather than in input_manager_create. This is because
creating seats must be done after server.input is set.

Lastly, it now stores the default seat name using a constant and removes
a second reference to seat0 (in input_manager_get_default_seat).

Ryan Dwyer ed771a6a6e Fix crash when view unmaps while no outputs connected
When a view unmaps, we call workspace_consider_destroy. This function
assumed the workspace would always have an output, but this is not the
case when hotplugged down to zero. The function now handles this and
allows itself to be destroyed when there is no output.

This means that workspace_begin_destroy must remove the workspace from
the root->saved_workspaces list to avoid an eventual dangling pointer,
so it does that now.

Lastly, when an output is plugged in again and it has to create a new
initial workspace for it, we must emit the workspace::init IPC event
otherwise swaybar shows no workspaces at all. I guess when you start
sway, swaybar is started after the workspace has been created which is
why this hasn't been needed earlier.

Rouven Czerwinski 1f0aeae335 view: rewarp cursor during view_unmap

Rouven Czerwinski 892446a0b6 view: move arrange_workspace into view_map
For mouse_warping cursor to correctly work on newly spawned containers,
the workspace needs to be arranged before the cursor is warped.

The shell functions each implement their own fullscreen and arrange checks,
move them into the view_map function and pass their states via boolean arguments.

Fixes #2819

Ryan Dwyer 26278b694c Introduce seat_set_raw_focus and remove notify argument from seat_set_focus_warp
This introduces seat_set_raw_focus: a function that manipulates the
focus stack without doing any other behaviour whatsoever. There are a
few places where this is useful, such as where we set focus_inactive
followed by another call to set the real focus again. With this change,
the notify argument to seat_set_focus_warp is also removed as these
cases now use the raw function instead.

A bonus of this is we are no longer emitting window::focus IPC events
when setting focus_inactive, nor are we sending focus/unfocus events to
the surface.

This also fixes the following:

* When running `move workspace to output <name>` and moving the last
workspace from the source output, the workspace::focus IPC event is no
longer emitted for the newly created workspace.
* When splitting the currently focused container, unfocus/focus events
will not be sent to the surface when giving focus_inactive to the newly
created parent, and window::focus events will not be emitted.

Ryan Dwyer 1059e173f4 Only damage popups when popups have damage
The previous behaviour was to damage the entire view, which would
recurse into each popup. This patch makes it damage only the popup's
surface, and respect the surface damage given by the client.

This adds listeners to the popup's map and unmap events rather than
doing the damage in the create and destroy functions. To get the popup's
position relative to the view, a new child_impl function get_root_coords
has been introduced, which traverses up the parents.

Ryan Dwyer c620f76bea Move sticky containers when switching workspace via criteria
* Create a view on workspace 1
* Switch to workspace 2 (on the same output) and create a floating
sticky view
* Use criteria to focus the view on workspace 1

Previously, we only moved the sticky containers when using
workspace_switch, but the above method of focusing doesn't call it. This
patch relocates the sticky-moving code into seat_set_focus_warp.

A side effect of this patch is that if you have a sticky container
focused and then switch workspaces, the sticky container will no longer
be focused. It would previously retain focus.

In seat_set_focus_warp, new_output_last_ws was only set when changing
outputs, but now it's always set. This means new_output_last_ws and
last_workspace might point to the same workspace, which means we have to
make sure we don't destroy it twice. It now checks to make sure they're
different, and to make this more obvious I've moved both calls to
workspace_consider_destroy to be next to each other.

Fix focusing topmost floating windows
Re-focus on the container on which the cursor hovers over.  A
special case is, if there are menus or other subsurfaces open
in the focused container.  It will prefer the focused container
as long as there are subsurfaces.

This commit starts caching the previous node as well as the
previous x/y cursor position.  Re-calculating the previous
focused node by looking at the current state of the cursor
position does not work, if the environment changes.

Fixes `hide_edge_borders smart` when gaps are in use.

Since `smart_borders on` is equivalent to `hide_edge_borders smart`
and `smart_borders no_gaps` is equivalent to `hide_edge_borders
smart_no_gaps`, I opted to just save the last value set for
`hide_edge_borders` and restore that on `smart_borders off`. This
simplifies the conditions for setting the border.

Ryan Dwyer 24bcb507ec Fix hotplugging down to zero outputs
When the last output is disconnected, output_disable is called like
usual and evacuates the output to the root->saved_workspaces list. It
then calls root_for_each_container to remove (untrack) the output from
each container's outputs list. However root_for_each_container did not
iterate the saved workspaces, so when the output gets freed the
containers would have a dangling pointer in their outputs list. Upon
reconnect, container_discover_outputs would attempt to use the dangling
pointer, causing a crash.

This makes root_for_each_container check the saved workspaces list,
which fixes the problem.

Ryan Dwyer 415a48ac63 Make gaps implementation consistent with i3-gaps
This changes our gaps implementation to behave like i3-gaps.

Our previous implementation allowed you to set gaps on a per container
basis. This isn't supported by i3-gaps and doesn't seem to have a
practical use case. The gaps_outer and gaps_inner properties on
containers are now removed as they just read the gaps_inner from the
workspace.

`gaps inner|outer <px>` no longer changes the gaps for all workspaces.
It only sets defaults for new workspaces.

`gaps inner|outer current|workspace|all set|plus|minus <px>` is now
runtime only, and the workspace option is now removed. `current` now
sets gaps for the current workspace as opposed to the current container.

`workspace <ws> gaps inner|outer <px>` is now implemented. This sets
defaults for a workspace.

This also fixes a bug where changing the layout of a split container
from linear to tabbed would cause gaps to not be applied to it until you
switch to another workspace and back.

Ryan Dwyer 138d10d5d6 Rename workspace_outputs to workspace_configs and fix memory leak
When we eventually implement `workspace <ws> gaps inner|outer <px>`,
we'll need to store the gaps settings for workspaces before they're
created. Rather than create a workspace_gaps struct, the approach I'm
taking is to rename workspace_outputs to workspace_configs and then add
gaps settings to that.

I've added a lookup function workspace_find_config. Note that we have a
similar thing for outputs (output_config struct and output_find_config).

Lastly, when freeing config it would create a memory leak by freeing the
list items but not the workspace or output names inside them. This has
been rectified using a free_workspace_config function.

Ryan Dwyer 22412f57b0 Fix floating views in tabbed/stacked workspaces not getting frame events

for floating containers.

This also moves the workspace_is_visible check to an earlier location
for performance reasons.

Ryan Dwyer 21ff87d72b Improve CSD logic
This does the following:

* Removes the xdg-decoration surface_commit listener. I was under the
impression the client could ignore the server's preference and set
whatever decoration they like using this protocol, but I don't think
that's right.
* Adds a listener for the xdg-decoration request_mode signal. The
protocol states that the server should respond to this with its
preference. We'll always respond with SSD here.
* Makes it so tiled views which use CSD will still have sway decorations
rendered. To do this, using_csd had to be added back to the view struct,
and the border is changed when floating or unfloating a view.

Ryan Dwyer 7b138e5ef0 Add CSD to border modes
This replaces view.using_csd with a new border mode: B_CSD. This also
removes sway_xdg_shell{_v6}_view.deco_mode and
view->has_client_side_decorations as we can now get these from the
border.

You can use `border toggle` to cycle through the modes including CSD, or
use `border csd` to set it directly. The client must support the
xdg-decoration protocol, and the only client I know of that does is the
example in wlroots.

If the client switches from SSD to CSD without us expecting it (via the
server-decoration protocol), we stash the previous border type into
view.saved_border so we can restore it if the client returns to SSD. I
haven't found a way to test this though.

Ryan Dwyer 4e4898e90f Fix race condition crash when view unmaps + maps quickly
When a view unmaps, we start a transaction to destroy the container,
then when the transaction completes we destroy the container and unset
the view's container pointer. But if the view has remapped in the
meantime, the view's container pointer will be pointing to a different
container which should not be cleared.

This adds a check to make sure the view is still pointing to the
container being destroyed before clearing the pointer. The freeing of
the title format is also removed as it is already freed when the view
destroys in view_destroy.

Ryan Dwyer b1a0e95e8e Fix crash when disconnecting output
If the output being disconnected contains views, and the views are being
relocated to another output of a different size, a transaction must
occur to reconfigure them. This means by the time
container_discover_outputs is called, the output is already disabled and
wlr_output is NULL.

I considered making it check output->wlr_output, but output->enabled
should work just as well and is more descriptive.

Ryan Dwyer 64445f4214 Prevent sticky containers from jumping on workspace switch
If you have swaybar docked to the top, and you create a floating sticky
container and switch workspaces on the same output, the sticky container
would move down by the height of swaybar on each switch.

This happens because when creating the workspace we set the dimensions
to the same as the output, then the subsequent arrange corrects it.
During this arrange, floating containers are translated so they stay
relative to the workspace. This translation needs to not occur for the
initial arrange.

This patch makes workspaces have a zero width and height when first
created, so we can detect whether this is the initial arrange and avoid
translating the floating containers if so.

Ryan Dwyer cb66bbea42 Allow running commands on containers without focusing them
This adds a `con` argument to `execute_command` which allows you to
specify the container to execute the command on. In most cases it leaves
it as `NULL` which makes it use the focused node. We only set it when
executing `for_window` criteria such as when a view maps. This means we
don't send unnecessary IPC focus events, and fixes a crash when the
criteria command is `move scratchpad` (because we can't give focus to a
hidden scratchpad container).

Each of the shell map handlers now check to see if the view has a
workspace. It won't have a workspace if criteria has moved it to the
scratchpad.

Ryan Dwyer 10ef118e09 Fix pango escaping and refactor escape_markup_text
Fixes #2674.

The cause of the issue was in get_pango_layout. When we call
pango_parse_markup, `text` is the escaped string, and the unescaped
string is then computed and written to `buf`. We were then passing the
unescaped string to pango_layout_set_markup, but this function needs the
escaped string. `buf` is not needed and has been removed.

The other part of this PR refactors escape_markup_text to remove the
dest_length argument and removes the -1 return value on error. It now
assumes that you've allocated dest to the correct length.

Ryan Dwyer bf5933c501 Implement tab cycling using mouse wheel
Firstly, a change had to be made to the container_at functions. If you
create layout `T[view H[view view]]` and hover the second tab, the
container_at functions would return the focus_inactive child. They now
return the split container itself. To compensate for this,
dispatch_cursor_button has been adjusted to find the focus_inactive
child before focusing it.

The actual implementation of wheel scrolling is pretty straightforward.
This uses handle_cursor_axis, so I took a similar approach to
handle_cursor_button (ie. creating a dispatch_cursor_axis function).

Ryan Dwyer c6ff1f67f1 Fix double iteration of scratchpad containers
root_for_each_container and root_find_container were using incorrect
logic to determine if a container was hidden in the scratchpad.
Containers will have a NULL parent if they are a direct child of a
workspace. Containers will have a NULL workspace if they are hidden in
the scratchpad.

The incorrect check meant that root_for_each_container would run the
callback on scratchpad containers twice. This meant that executing a
command such as `[class="$something"] scratchpad show` would cause the
command to run twice, resulting in the container being shown and hidden
again which is effectively a no op.

Fixes #2655.

this case the parent hadn't yet been added to the workspace which meant
con->workspace was NULL.

The fix makes container_handle_fullscreen_reparent return if there's no
workspace, and the fullscreen pointer is reapplied in
workspace_wrap_children.

This does the following:

* Adds a baseline argument to get_text_size (the baseline is the
distance from the top of the texture to the baseline).
* Stores the baseline in the container when calculating the title
height.
* Takes the baseline into account when calculating the config's max font
height.
* When rendering, pads the textures according to the baseline so they
line up.

Ryan Dwyer 635ae9557c Second attempt at restoring focus when closing a fullscreen view
To reproduce the problem this is fixing, create H[view view view],
fullscreen one of the views and close it. The entire workspace will be
given focus rather than one of the siblings.

This happens because we emit the destroy event, so the seat code tries
to find a new focus, but the view it finds is still believed to be
hidden by the fullscreen view so it's discarded and the workspace is
used instead.

This clears the workspace's fullscreen pointer prior to emitting the
destroy event so that the seat code finds an appropriate new focus.

Ryan Dwyer 908095ef9a Introduce seat_set_focus_container and seat_set_focus_workspace
These are the same as seat_set_focus, but accept a specific type rather
than using nodes. Doing this adds more typesafety and lets us avoid
using &con->node which looks a little ugly.

This fixes a crash that pretty much nobody would ever come across. If
you have a bindsym for "focus" with no arguments and run it from an
empty workspace, sway would crash because it assumes `container` is not
NULL.

Ryan Dwyer c6368febc8 Adjust container box
Prior to f5b9815128, children of tabbed
and stacked containers would have their container size and position set
to the same as the tabbed/stacked container. Normally this would be a
problem for a layout such as T[V[view]], but there was some code in the
arrange functions which would check if the grandparent of the view was a
tabbed or stacked container and would offset the view's Y accordingly.

Commit f5b9815128 changed the box to
exclude the titlebar for all tabbed/stacked children so that the
grandparent check could be removed. But this meant the title was not
covered in the container and wasn't damaged when the child changed its
title.

This patch changes it so that a child of a tabbed/stacked container will
have its box include the title bar if the child is a view, but not if
it's a layout container. This fixes the title damage issue while
avoiding the grandparent check in the arrange functions, and matches
what we see visually.

Ryan Dwyer 7586f150c0 Implement type safe arguments and demote sway_container
This commit changes the meaning of sway_container so that it only refers
to layout containers and view containers. Workspaces, outputs and the
root are no longer known as containers. Instead, root, outputs,
workspaces and containers are all a type of node, and containers come in
two types: layout containers and view containers.

In addition to the above, this implements type safe variables. This
means we use specific types such as sway_output and sway_workspace
instead of generic containers or nodes. However, it's worth noting that
in a few places places (eg. seat focus and transactions) referring to
them in a generic way is unavoidable which is why we still use nodes in
some places.

If you want a TL;DR, look at node.h, as well as the struct definitions
for root, output, workspace and container. Note that sway_output now
contains a workspaces list, and workspaces now contain a tiling and
floating list, and containers now contain a pointer back to the
workspace.

There are now functions for seat_get_focused_workspace and
seat_get_focused_container. The latter will return NULL if a workspace
itself is focused. Most other seat functions like seat_get_focus and
seat_set_focus now accept and return nodes.

In the config->handler_context struct, current_container has been
replaced with three pointers: node, container and workspace. node is the
same as what current_container was, while workspace is the workspace
that the node resides on and container is the actual container, which
may be NULL if a workspace itself is focused.

The global root_container variable has been replaced with one simply
called root, which is a pointer to the sway_root instance.

The way outputs are created, enabled, disabled and destroyed has
changed. Previously we'd wrap the sway_output in a container when it is
enabled, but as we don't have containers any more it needs a different
approach. The output_create and output_destroy functions previously
created/destroyed the container, but now they create/destroy the
sway_output. There is a new function output_disable to disable an output
without destroying it.

Containers have a new view property. If this is populated then the
container is a view container, otherwise it's a layout container. Like
before, this property is immutable for the life of the container.

Containers have both a `sway_container *parent` and
`sway_workspace *workspace`. As we use specific types now, parent cannot
point to a workspace so it'll be NULL for containers which are direct
children of the workspace. The workspace property is set for all
containers, except those which are hidden in the scratchpad as they have
no workspace.

In some cases we need to refer to workspaces in a container-like way.
For example, workspaces have layout and children, but when using
specific types this makes it difficult. Likewise, it's difficult for a
container to get its parent's layout when the parent could be another
container or a workspace. To make it easier, some helper functions have
been created: container_parent_layout and container_get_siblings.

container_remove_child has been renamed to container_detach and
container_replace_child has been renamed to container_replace.

`container_handle_fullscreen_reparent(con, old_parent)` has had the
old_parent removed. We now unfullscreen the workspace when detaching the
container, so this function is simplified and only needs one argument
now.

container_notify_subtree_changed has been renamed to
container_update_representation. This is more descriptive of its
purpose. I also wanted to be able to call it with whatever container was
changed rather than the container's parent, which makes bubbling up to
the workspace easier.

There are now state structs per node thing. ie. sway_output_state,
sway_workspace_state and sway_container_state.

The focus, move and layout commands have been completely refactored to
work with the specific types. I considered making these a separate PR,
but I'd be backporting my changes only to replace them again, and it's
easier just to test everything at once.

Ryan Dwyer f5b9815128 Prepare arrange code for type safe arguments
This commit changes the arrange code in a way that will support type
safe arguments.

The arrange_output et al functions are now public, however I opted not
to use them directly yet. I've kept the generic arrange_windows there
for convenience until type safety is fully implemented. This means this
patch has much less risk of breaking things as it would otherwise.

To be type safe, arrange_children_of cannot exist in its previous form
because the thing passed to it could be either a workspace or a
container. So it's now renamed to arrange_children and accepts a list_t,
as well as the parent layout and parent's box.

There was some code which checked the grandparent's layout to see if it
was tabbed or stacked and adjusted the Y offset of the grandchild
accordingly. Accessing the grandparent layout isn't easy when using type
safe arguments, and it seemed odd to even need to do this. I determined
that this was needed because a child of a tabbed container would have a
swayc Y matching the top of the tab bar. I've changed this so a child of
a tabbed container will have a swayc Y matching the bottom of the tab
bar, which means we don't need to access the grandparent layout.  Some
tweaks to the rendering and autoconfigure code have been made to
implement this, and the container_at code appears to work without
needing any changes.

arrange_children_of (now arrange_children) would check if the parent had
gaps and would copy them to the child, effectively making the
workspace's gaps recurse into all children. We can't do this any more
without passing has_gaps, gaps_inner and gaps_outer as arguments to
arrange_children, so I've changed the add_gaps function to retrieve it
from the workspace directly.

apply_tabbed_or_stacked_layout has been split into two functions, as it
had different logic depending on the layout.

Lastly, arrange.h had an unnecessary include of transaction.h. I've
removed it, which means I've had to add it to several other files.

Ryan Dwyer 5dbbab7bdc Remove layout.c
When we have type safety we'll need to have functions for
workspace_add_tiling and so on. This means the existing container
functions will be just for containers, so they are being moved to
container.c. At this point layout.c doesn't contain much else, so I've
relocated everything and removed the file.

* container_swap and its static functions have been moved to the swap
command and made static.
* container_recursive_resize has been moved to the resize command and
made static.
* The following have been moved to container.c:
    * container_handle_fullscreen_reparent
    * container_insert_child
    * container_add_sibling
    * container_add_child
    * container_remove_child
    * container_replace_child
    * container_split
* enum movement_direction and sway_dir_to_wlr have been moved to util.c.

Side note: Several commands included layout.h which then included
root.h. With layout.h gone, root.h has to be included by those commands.

Ryan Dwyer f4bc25bcc6 Relocate container_move, container_move_to and container_get_in_direction
* container_move is only called from the move command
* container_move_to was called from both the move command and the sticky
command, but the sticky command can easily not call it
* container_get_in_direction is only called from the focus command

Moving these functions to their respective commands gives better
separation of code and removes bloat from layout.c. These functions will
need to be refactored to take advantage of type safety, so separating
them will make this easier to refactor.

The following static functions have also been moved:

* is_parellel
* invert_movement
* move_offs
* container_limit
* workspace_rejigger
* move_out_of_tabs_stacks
* get_swayc_in_output_direction

They were all used by the move functions, except for the last one which
is used by focus.

Other changes:

* index_child has been renamed to container_sibling_index, moved to
container.c and made public
* sway_output_from_wlr has been renamed to output_from_wlr_output, moved
to output.c and made public
* container_handle_fullscreen_reparent has been made public
* sway_dir_to_wlr has been made public

No changes have been made to any of the moved functions, other than
updating calls to functions that have been renamed.

Ryan Dwyer b6058703fa Refactor destroy functions and save workspaces when there's no outputs
This changes the destroy functions to the following:

* output_begin_destroy
* output_destroy
* workspace_begin_destroy
* workspace_destroy
* container_begin_destroy
* container_destroy
* view_begin_destroy
* view_destroy

The terminology was `destroy` and `free`, and it has been changed to
`begin_destroy` and `destroy` respectively.

When the last output is disconnected, its workspaces will now be stashed
in the root. Upon connection of a new output they will be restored.

There is a new function `workspace_consider_destroy` which decides
whether the given workspace should be destroyed or not (ie. empty and
not visible).

Calling container_begin_destroy will no longer automatically reap the
parents. In some places we want to reap the parents and in some we
don't, so this is left to the caller.

container_reap_empty_recursive and container_reap_empty have been
combined into one function and it will recurse up the tree.

Ryan Dwyer e1d5dc0804 Translate floating containers when a workspace is moved
When a workspace is moved to another output, or the output it's on
changes its global layout position, the floating containers on that
workspace should be translated by the same amount as the workspace. This
keeps the floating containers in the same position relative to the
workspace.

A check is done to make sure the floating container's center point isn't
being moved off screen. If it is, it is centered within the workspace.

Ryan Dwyer 771ad7bffa Fix jumping views
Fixes #2490.

To be honest I'm not sure why this fixes the issue.

I observed that I could only make the view jump if I resized it to the
smallest possible size first. Then I had a suspicion that we were
accidentally factoring in the title and border sizes into the view size
when it uses CSD. So I changed that and it appears to have fixed the
jumping issue.

I guess when we factor the title and borders in, we send a configure to
the surface with a size smaller than the minimum, and it comes back with
a surface at the minimum size. We interpret this as an unexpected
resize, and this somehow makes it jump.

Ryan Dwyer 0f6d212629 Send output enter/leave events correctly
Previously we used a reparent event to detect when a view changes
parent, then sent an output enter/leave to the surfaces if needed. This
worked for tiling views but not floating views, as floating views can
intersect another output without changing parent.

The solution implemented for floating views also applies cleanly to
tiling views, so the previous method has been completely replaced and
the reparent event has been removed.

This introduces a new function container_discover_outputs. This function
compares the container's `current` position to the outputs, sends enter
and leave events as needed, and keeps track of which outputs it's
intersecting in a new `container->outputs` list. If it has entered a new
output with a different scale then the title and marks textures will
also be recreated at the new scale.

The function is called when a transaction applies. This is convenient as
it means we don't have to call it from various places.

There is imperfect rendering when a floating view overlaps two outputs
with different scales. It renders correctly for the most recently
entered output, but there is only one title texture so it renders
incorrectly on the old output.

Ryan Dwyer 2b5a404ac9 Replace hacky L_FLOATING container with a list
Workspaces previously had a magical `workspace->floating` container,
which had a layout of L_FLOATING and whose children were actual floating
views. This allowed some conveniences, but was a hacky solution because
the container has to be exempt from focus, coordinate transactions with
the workspace, and omit emitting IPC events (which we didn't do).

This commit changes it to be a list directly in the sway_workspace. The
L_FLOATING layout is no longer used so this has been removed as well.

* Fixes incorrect check in the swap command (it checked if the
containers had the L_FLOATING layout, but this layout applied to the
magical container).

This introduces the following `for_each` functions:

* root_for_each_workspace
* root_for_each_container
* output_for_each_workspace
* output_for_each_container
* workspace_for_each_container

And introduces the following `find` functions:

* root_find_output
* root_find_workspace
* root_find_container
* output_find_workspace
* output_find_container
* workspace_find_container
* container_find_child

And removes the following functions:

* container_descendants
* container_for_each_descendant
* container_find

This change is preparing the way for demoting sway_container. Eventually
these functions will accept and return sway_outputs, sway_workspaces and
sway_containers (meaning a C_CONTAINER or C_VIEW).

This change also makes it easy to handle abnormalities like the
workspace floating list, root's scratchpad list and (once implemented)
root's saved workspaces list for when there's no connected outputs.

Ryan Dwyer 701fcafc70 Use list_find in more places and refactor/fix workspace prev_next functions
The original purpose of this commit is to replace some for loops with
list_find. But while doing this I found the workspace_prev_next_impl
functions to be difficult to read and also contained a bug, so I
refactored them and fixed the bug.

To reproduce the bug:

* Have two outputs, where the left output has workspaces 1, 2, 3 and the
right output has workspaces 4, 5, 6. Make workspace 2 focused_inactive
and workspace 4 focused.
* Run `workspace prev`.
* Previously it would visit the left output, then apply `workspace prev`
to workspace 2, which focuses workspace 1.
* Now it will focus the rightmost workspace on the left output
(workspace 3).

The refactoring I made to the workspace functions are:

* Added the static keyword.
* They now accept an int dir rather than bool, to avoid an unnecessary
conversion.
* Rather than preparing start and end variables for the purpose of
iterating, just iterate everything.
* Replace for loops with list_find.
* Don't call workspace_output_prev_next_impl (this fixes the bug).

been sent, it now stores a single instruction.
* Containers now have an ntxnrefs property. Previously we knew how many
references there were by the length of the instruction list.
* Instructions no longer need a ready property. It was used to avoid
marking an instruction ready twice when they were in a list, but this is
now avoided because there is only one instruction and we nullify the
container->instruction pointer when it's ready.
* When a transaction applies, we no longer need to consider releasing
and resaving the surface, as we know there are no other committed
transactions.
* transaction_notify_view_ready has been renamed to
view_notify_view_ready_by_serial to make it consistent with
transaction_notify_view_ready_by_size.
* Out-of-memory checks have been added when creating transactions and
instructions.

minus 18e425eda6 Use assigned workspace name for output
Instead of relying on bindings being configured, primarily source
new workspace names from workspace-output assignments.

Ryan Dwyer 4ad1ccc9dc Remove container_for_each_descendant_bfs
The function was not used.

Also renames container_for_each_descendant_dfs to just
container_for_each_descendant.

In all cases you can use container_has_ancestor with the arguments
swapped, which is faster than container_has_child.

Ryan Dwyer 5653fc754b Deny moving a sticky container to workspace if it's the same output
Rationale: Sticky containers are always assigned to the visible
workspace.

The basic idea here is to check the destination's output (move.c:190).
But if the command was `move container to workspace x` then a workspace
might have been created for it. We could destroy the workspace in this
case, but that results in unnecessary IPC events.

To avoid this, the logic for `move container to workspace x` has been
adjusted. It now delays creating the workspace until the end, and uses
`workspace_get_initial_output` to determine and check the output before
creating it.

Ryan Dwyer a0649190de Fix edge cases when moving floating container to new workspace
* Removes container_floating_move_to_container, instead opting to put
that logic in container_move_to
* In the seat code, focusing a floating view now updates the pending
state only and lets the next transaction carry it over to the current
state. This is required, otherwise it would crash.
* When unfullscreening a floating container, an output check is now done
to see if it should center it.

Ryan Dwyer 50f3a7ff5c Fix infinite loop when focusing sticky containers via workspace command
In a multi-output setup, if a sticky container is on one output and
focus is on the other output, and you run (eg) `workspace 1` to focus
the workspace containing the sticky container, an infinite loop would
occur. It would loop infinitely because it would remove the sticky
container from the workspace, add it back to the same workspace, and
then decrement the iterator variable.

The fix just wraps the loop in a workspace comparison.

Ryan Dwyer f57a3919cf Move workspace moving code out of container_move_to
container_move_to handled moving containers to new parents, as well as
moving workspaces to new outputs.

This commit removes the workspace-moving code from this function and
introduces workspace_move_to_output. Moving workspaces using
container_move_to only happened from the move command, so it's been
implemented as a static function in that file.

Simplifying container_move_to makes it easier for me to fix some issues
in #2420.
