free_damage and detach_pixmap functions are called inside dispose and an object
can be disposed multiple times, even when the display is already closed.
So, don't try to deference a possibly null-pointer, assigning the xdisplay too
early, as if the X11 related resources have been unset, the server might not be
open anymore. In fact, we assume that if we have a damage or a pixmap set,
the display is still open.

In MetaWindowActor creation we're setting the compositor private (i.e. the
window actor itself) of a window before creating the surface actor, and so
passing to the it a window without its compositor side set.
Since the surface actor might use the parent actor, set this before updating
the surface.

If something (i.e. gnome-shell or an extension) tries to activate an unmanaged

(cherry picked from commit a6fc656e917fd48b8708b8d9f4bf9f8b15581313)
When requesting to a take-focus window to acquire the input, the client may or
may not respond with a SetInputFocus (this doesn't happen for no-input gtk
windows in fact [to be fixed there too]), in such case we were unsetting the
focus while waiting the reply.
In case the client won't respond, we wait for a small delay (set to 250 ms) for
the take-focus window to grab the input focus before setting it to the default
window.
Added a test for this behavior and for the case in which a window takes the
focus meanwhile we're waiting to focus the default window.

Currently the EGLDevice code gets the display and calls eglInitialize.
As a follow-up it checks the required EGL extensions - technically it
could check the EGL device extensions earlier.
In either case, eglTerminate is missing. Thus the connection to the
display was still bound.
This was highlighted with Mesa commit d6edccee8da ("egl: add
EGL_platform_device support") + amdgpu.
In that case, since the eglTerminate is missing, we end up reusing the
underlying amdgpu_device due to some caching in libdrm_amdgpu. The
latter in itself being a good solution since it allows buffer sharing
across primary and render node of the same device.
Note: we should really get this in branches all the way back to 3.30.

When the compositor is destroyed we should cleanup the list of window actors we
created and destroy them.
Since all the actors are added to the window_group or top_window_group we can
just destroy these containers (together with the feedback_group), and simply
free the windows list.
This is particularly needed under X11 because before we destroy the display, we
might do some cleanups as detaching the surface pixmaps and freeing the damages
and if this happens at later point (for example when triggered by garbage
collector in gnome-shell), we might crash because the x11 dpy reference is
already gone.
Destroying the window actors instead, ensures we avoid any further call to X11
related functions and that we release the actors XServer resources.

When focus stealing prevention kicks in, mutter would set the demand
attention flag on the window.
Focus stealing prevention would also prevent the window from being
raised and focused, which is expected as its precisely its purpose.
Yet, when that occurs, the user expects the window which has just been
prevented from being focused to be the next one in the MRU list, so
that pressing [Alt]-[Tab] would raise and give focus to that window.
This works fine when the window is placed on the primary monitor, but
not when placed on another monitor, in which case the window which has
been denied focus is placed ahead of the MRU list and pressing
[Alt]-[Tab] would leave the focus on the current window.
This is because of a mechanism in `meta_display_get_tab_list()` which
forces the windows with the demand attention flag set to be placed first
in the MRU list when they're placed on a workspace different from the
current one.
But because workspaces apply only to the primary monitor (by default),
the windows placed on other outputs have their workspace set to `NULL`
which forces them ahead of the MRU list by mistake.
Fix this by using the appropriate `meta_window_located_on_workspace()
function to check if the window is on another workspace.

`clutter-stage-cogl` would then have `pending_swaps` permanently stuck
above zero preventing the presentation timing logic from being used.
The problem is that a boolean can only count to one, but in some cases
(triple buffering, whether intentional or accidental #334) we need it to
count to two. So just change booleans to integers and count properly.
