This commit implements the StatusNotifierItem protocol, and enables
swaybar to show tray icons. It also uses `xembedsniproxy` in order to
communicate with xembed applications.
The tray is completely optional, and can be disabled on compile time
with the `enable-tray` option. Or on runtime with the bar config option
`tray_output none`.
Overview of changes:
In swaybar very little is changed outside the tray subfolder except
that all events are now polled in `event_loop.c`, this creates no
functional difference.
Six bar configuration options were added, these are detailed in
sway-bar(5)
The tray subfolder is where all protocol implementation takes place and
is organised as follows:
tray/sni_watcher.c:
This file contains the StatusNotifierWatcher. It keeps track of
items and hosts and reports when they come or go.
tray/tray.c
This file contains the StatusNotifierHost. It keeps track of
sway's version of the items and represents the tray itself.
tray/sni.c
This file contains the StatusNotifierItem struct and all
communication with individual items.
tray/icon.c
This file implements the icon theme protocol. It allows for
finding icons by name, rather than by pixmap.
tray/dbus.c
This file allows for asynchronous DBus communication.
See #986#343
This change allows using numeric character references in workspace names
- for example æ which stands for sharp s. A fix was necessary in
get_pango_layout, since markup and parsed markup had different width.
When using a bar on a named output, load_swaybars() requires the
output to be active (ie. in the root container), but this is not the case if
the bar is added to the last output. To fix this, load_swaybars() is now
called after the output has been added to the root container.
After fixing that, swaybar would segfault due to using the wrong index
variable when loading outputs and config.
When headers were installed in more sofisticated places (but package
config knows it right), it revealed missing paths in CMake
configuration. Lets fix it.
In the i3bar protocol the value of the markup field is a string: "pango"
or "none" rather than a bool. This patch makes swaybar compatible with
that.

Calling `exit` in sway_terminate prevents sway from correctly shutting
down (freeing data, cleanly terminating the ipc server, etc.).
A better way is to exit straight away if the failure occurs before
`wlc_run` and use sway_abort as usual if it occur when wlc is running.
