If we fail to find the IDLETIME counter, then the alarm variable will be
uninitialised. Most code paths are careful to check this before
submitting XSync calls, but there is one check missing.

window: don't set _NET_WM_FULLSCREEN_MONITORS to bogus values
Prior to the DisplayConfig merge, we would set _NET_WM_FULLSCREEN_MONITORS
to (unsigned)-1 when unset. After that, we would have invalid
reads inside meta_screen_monitor_index_to_xinerama_index() (called
with -1).
The way I read the specification, the proper way to indicate
that the window is back to fullscreen on all monitors is to
remove the property, so do that.
Also, add an assertion that meta_screne_monitor_index_to_xinerama_index()
is doing the right thing.
monitorManager: Fix logic bug in make_logical_config
The code that prevents the creation of multiple MonitorInfos for clones
wasn't working due to using the wrong index when getting the already
created info so fix that to use the correct one.
window-actor: Fix unobscured_region handling when computing paint volume
We currently ignore the unobscured region when we have mapped clones in
meta_window_actor_process_damage and meta_window_actor_damage_all but
use it unconditionally when computing the paint volume.
This is wrong. We should ignore it there as well or we will end up with
empty clones if the cloned window is completly obscured
(like the tray icons in gnome-shell).
