* Use m_connection.poll_for_event
* fix: Handle X events before polling for IO
Polling the XCB file descriptor for X events doesn't detect events that
are already in XCB's event queue but not yet handled.
If this happens, the eventloop polls for IO and the queued events wait
until another event arrives, causing some desyncs in the bar.
This can easily happen if something (e.g. a click event) triggers some
xcb calls, which as a consequence buffer some incoming events.
We "fix" this by adding a libuv prepare handle (which runs right before
polling for IO) that processes pending X events.
The background_manager used the root window depth for creating its
pixmaps, but when the root pixmap has a different depth, this causes the
copy_area_checked call to fail and crash the bar.
We now load the root pixmap before finding the visual and creating the
slice pixmaps.

The issue was that the event was for the wrapper window and that the
tray_client's move constructors didn't correctly copy over all data and
so when the m_clients vector grew, it corrupted the state of all
existing clients.
Each tray client is directly reparented to the bar window. This saves us
the hassle of having to configure a basically useless tray window and
keeping its background pixmap in sync.
The only disadvantages are having to (un)map each client window
individually and calculating its position relative to the bar window
(which changes all the time) instead of relative to the tray window
(which only changes when clients are added/removed).
If any rendered text uses a non-integer number of pixels (often emojis),
rendering of subsequent text blocks will start between pixels which
results in small gaps in the background and over/underline colors caused
by cairo only rendering at fractional-intensity in the beginning and end
pixel.
Simply rounding up text width can solve this.

If context_state_callback is called before we call
pa_threaded_mainloop_wait in the main thread, the signal is lost and we
wait forever.

When a module is clicked, only wait for the double click interval if a
double click action is associated with that module. Otherwise trigger
the click right away.
