novenary dbc326ba84 Don't apply hide_edge_borders to any floating container
This fixes the following scenario:
- Place a floating window so its border is right at the edge of the
  screen
- Create a new split
- The border disappears
- Moving the window does not restore the border

Rouven Czerwinski 30e400c0a3 view: handle case where map_ws is NULL
When a criteria places the view into the scratchpad, map_ws is NULL and

Kenny Levinsen 1a6471be17 view: Set parent for view_child subsurfaces on init
view_child_init was calling view_init_subsurfaces, which did not set the
parent attribute for the subchildren. This lead to the subchildren
acting as standalone children. If the parent was an xdg_popup, this
would make the subchild unaware of the popup position.

Introduce view_child_init_subsurfaces for view_child_init to use
instead.

Kenny Levinsen a047b5ee4a container: Move pending state to state struct
Pending state is currently inlined directly in the container struct,
while the current state is in a state struct. A side-effect of this is
that it is not immediately obvious that pending double-buffered state is
accessed, nor is it obvious what state is double-buffered.

Instead, use the state struct for both current and pending.

Tudor Brindus 07042486c3 tree/container: introduce container_is_sticky[_or_child] functions
To query whether a container is sticky, checking `con->is_sticky` is
insufficient. `container_is_floating_or_child` must also return true;
this led to a lot of repetition.

This commit introduces `container_is_sticky[_or_child]` functions, and
switches all stickiness checks to use them. (Including ones where the
container is already known to be floating, for consistency.)

Dimitris Triantafyllidis 0cb9282aee Smart borders fix: always show borders for floating containers
Currently, in view_autoconfigure, the only condition for show_border
is !view_is_only_visible. view_is_only_visible does not cross the
boundary between the workspace's tiling and floating lists and does not
differentiate between them.

The result is, that in a workspace with zero or more tiling containers
and a single floating container, the floating container will lose its
borders as soon as it is split, provided that a only one view is visible
within the floating container.

Fixed by adjusting the condition for show_borders.

Johan Bjäreholt 1f8dbb320a tree/view: Make foreign-toplevel app_id fallback to class
It is not a part of the foreign-toplevel-management protocol to get the
class of a toplevel, only for getting the app_id.
For xwayland clients this is an issue because that means that you cannot
identify what application the toplevel refers to which is the point of
the app_id property.

By falling back to class when an app_id does not exist solves this problem.

Phoc also uses app_id and class interchangeably in their implementation
of foreign-toplevel-management, in fact they always do that and not only
for just this protocol.

Michael Weiser 0f11aa037a commands: Add per-view shortcuts_inhibitor command
Add a separate per-view shortcuts_inhibitor command that can be used
with criteria to override the per-seat defaults. This allows to e.g.
disable shortcuts inhibiting globally but enable it for specific,
known-good virtualization and remote desktop software or, alternatively,
to blacklist that one slightly broken piece of software that just
doesn't seem to get it right but insists on trying.

Add a flag to sway_view and handling logic in the input manager that
respects that flag if configured but falls back to per-seat config
otherwise. Add the actual command but with just enable and disable
subcommands since there's no value in duplicating the per-seat
activate/deactivate/toggle logic here. Split the inhibitor retrieval
helper in two so we can use the backend half in the command to retrieve
inhibitors for a specific surface and not just the currently focused
one. Extend the manual page with documentation of the command and
references to its per-seat sibling and usefulness with criteria.

Pedro Côrte-Real d0233af3b3 Rework gaps code to be simpler and correct
Instead of tracking gaps per child apply gaps in two logical places:

1. In tiled containers use the layout code to add the gaps between
windows. This is much simpler and guarantees that the sizing of children
is correct.
2. In the workspace itself apply all the gaps around the edge. Here
we're in the correct position to size inner and outer gaps correctly and
decide on smart gaps in a single location.
