Implement Tray Icons
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.
