The override_redirect flag can change on configure notify and
on map notify. This adds an event to know when it changes.
This removes wlr_xwayland_surface_is_unmanaged which was wrongly
using the window type to decide whether the view should be
unmanaged.
A similar patch was proposed to Weston, but has never been
merged upstream [1].

Makes the xwayland startup process two phased.
The first phase just initialises the X11 sockets.
The second phase starts the Xwayland server itself.
When starting xwayland lazily the second phase will be postponed until
a client has connected to the X11 socket.
Changes in behaviour:
The DISPLAY environment is now set immediately after the X11 sockets
are created.
When the Xwayland server is killed or crashes, the sockets will not be
recreated, but reused.
Fixes#849: Start up Xwayland lazily
Some comboboxes (e.g. in chrome://flags) are advertized as…
Notifications of course! Yeah, notifications, the thing that
tells you you have mail, your battery is low, or the dog has
eaten your carpet. This isn't the first time we notice Chromium's
X11 backend is pretty shit.
Anyway, added notifications and splash screens to the list of
unmanaged windows. Also removed utility windows because those
should be managed, but maybe I'm wrong and I'll revert this.
This unbreaks the build on armhf that otherwise fails like
