It seems that sometimes these functions are called by Javascript in
GNOME Shell during tear down. This causes segfaults and crash reports,
but without any backtraces other than the entry and exit points into
gjs.
In order to get more useful information about where these calls come
from, validate the input passed gracefully, by complaining in the log
and returning NULL values.

Move out updating of various shapes (input, opaque, shape) indirectly
from X11 to the corresponding X11 sub types of MetaWindowActor and
MetaSurfaceActor.
Also move fullscreen window unredirection code with it. We want to
effectively do something similar for MetaCompositorServer, but it will
work differently enough not to share too much logic.
While it would have been nice to move things piece by piece, things were
too intertwined to make it feasible.
This has the side effect fixing accidentally and arbitrarily adding
server side shadow to Wayland surfaces.

The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendX11, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

A base type shouldn't know about sub types, so let MetaDisplay make
the correct choice of what type of MetaCompositor it should create. No
other semantical changes introduced.

Introduce MetaCompositorX11, dealing with being a X11 compositor, and
MetaCompositorServer, being a compositor while also being the display
server itself, e.g. a Wayland display server.

Waking up gnome-shell and triggering JavaScript listeners of
`size-changed` every time a window was only moved was wasting a lot
of CPU.
This cuts the CPU requirement for dragging windows by around 22%.

The way code was structured made it easy to misunderstand things as the
surface actor of a window actor could change over time. So is not the
case, however, the intention of the corresponding "update" function was
so that a surface actor could be assigned to a window actor as soon as
the X11 window was associated with its corresponding wl_surface, if the
window in question came from Xwayland.
Restructure the code and internal API a bit to make it clear that a
window actor only once gets a surface actor assigned to it, and that it
after that point never changes.

Everytime the top window changes we connect/disconnect to the actor's destroy
signal, although as explained in commit ba8f5a11 this might be slower in case
the window actor has many other signal connections.
So, just track this using an ID.

We're currently emitting the 'grab-op-end' signal when the grab prerequisites
are met, but when display->grab_op is still set to a not-NONE value and thus
meta_display_get_grab_op() would return that in the signal callback.
And more importantly when this is emitted, devices are still grabbed.
Instead, emit this signal as soon as we've unset all the grab properties and
released the devices.

Code underneath seems to handle errors properly, and this is apparently
here to save a few XSync()s on X11. Just drop this windowing dependent
bit to make things cleaner.

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.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/576
MetaWindowActor breaks layering isolation by accessing
and injecting itself into compositor->windows. This is
a bad practice, and effecticely makes returning the
new actor useless, since we doesn't even use the return
value.
Move window actor creation to under MetaCompositor and
stop violating (too badly) the resposabilities of each
component. This moves meta_window_actor_new() into
meta_compositor_add_window().
Also, move the remaining initialization code to the
GObject.constructed vfunc.

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
The compositor will automatically unredirect the top most window which
is fully visible on screen. When unredirecting windows, it also shapes
the compositor overlay window (COW) so that other redirected windows
still shows correctly.
The function `get_top_visible_window_actor()` however will simply walks
down the window list, so if a window is placed on a layer above and
unredirected, then iconified by the client, it will still be picked up
by `get_top_visible_window_actor()` and he compositor will reckon it's
still unredirected while not in a visible state anymore, thus leaving a
black area on screen.
Make sure we skip the windows not known to the compositor while picking
the top visible window actor to avoid this issue.

- Stop using CurrentTime, introduce META_CURRENT_TIME
- Use g_get_monotonic_time () instead of relying on an
X server running and making roundtrip to it

Split X11 specific parts into MetaX11Display. This also required
changing MetaScreen to stop listening to any signals by itself, but
instead relying on MetaDisplay forwarding them. This was to ensure the
ordering. MetaDisplay listens to both the internal and external
monitors-changed signal so that it can pass the external one via the
redundant MetaDisplay(prev MetaScreen)::monitors-changed.

They are X11 specific functions, used for X11 code. They have been
improved per jadahl's suggestion to use gdk_x11_lookup_xdisplay and
gdk_x11_display_error_trap_* functions, instead of current code.

While MetaStage, MetaWindowGroup and MetaDBusDisplayConfigSkeleton don't
appear explicitly in the public API, their gtypes are still exposed via
meta_get_stage_for_screen(), meta_get_*window_group_for_screen() and
MetaMonitorManager's parent type. Newer versions of gjs will warn about
undefined properties if it encounters a gtype without introspection
information, so expose those types to shut up the warnings.

When the top window actor is destroyed, we need to make sure that
all its references are removed or it could be picked again in next
windows sync, causing crashes.
Since the window might or might not be destroyed when removed (depending
weather animations are in progress over it or not), it's just safer
to wait it to be destroyed before cleaning up any of its reference.

We must emit ::dnd-leave to pair the ::dnd-enter that shall be
emitted whenever the plugin grab begins, otherwise we leave
listeners unable to clean up if the plugin begins and ends a
grab while there is an ongoing DnD operation.

When determining whether we should unredirect a window or not, ignore
offscreen windows, and just check the top most visible window.
Previously this was not an issue, but since 'stack-tracker: Keep
override redirect windows on top' we started sorting the UI frames
window, which is an offscreen override redirect window, on top, causing
the unredirect checking code to always check whether to unredirect the
UI frames window. This effectively disabled the compositor bypass
functionality.
