We passed the pointer to a GError * as user data on an async I/O call.
The callback function didn't make use of it, so it was never written to,
thus remained NULL, thus was dead code. Remove it.

The event-route is never set to COMPOSITOR_GRAB nowadays, so the
condition will never be met.
Furthermore, it is expected that ClutterGrabs only happen when
events are routed normally, so the remaining NORMAL check should
already fully cover the old COMPOSITOR_GRAB case.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2436>
We already bypass wayland if there is a ClutterGrab, so the case
that used to be covered by the event-route check is already handled,
and we can just remove the obsolete check.

The code is already trying to avoid creating new laters when there
already is one for the queue type, but this wasn't working because the
ID of the later was never stored after creating a new one. This would
then result in as many laters as meta_display_queue_window() was called
and all of them would run the handler function, even if only the first
one had a non-empty window queue.
Similarly this was causing the later to not be removed if the window
queue got empty after meta_display_unqueue_window().

Currently the signal is getting emitted accidentally, because even when
removing a window from the queue, the later handler of that queue will
still get run due to a bug. This bug is going to get fixed in the next
commit, but some things might depend on the signal getting emitted when
the visibility of a window has changed.
This change affects the behavior in two ways. First the signal is now
emitted immediately rather than from an idle. And second it now
correctly includes the window in the should_show or should_hide list.

Prior to 'compositor: Destroy actors when unmanaging', window actors
were destroyed when the compositor object was destroyed, long after the
windows were unmanaged, however, when this instead changed to happen
when unmanaging, with the original goal to avoid having these actors try
to interact with the disposed MetaCompositor instance, it caused an
issue where window actors would be indirectly destroyed as a side effect
of their parents being destroyed, which caused some fallout in the logic
handling window-close animation tracking, which relies on
meta_window_actor_queue_destroy() being called before a window actor is
actually destroyed.
Fix this by unmanaging windows before unmanaging the compositor.
From an X11 point of view, this should be harmless, since all it really
do is call XCompositeUnredirectSubwindows().
For the native backend and the common behavior, all unmanaging the
compositor instance does is destroy clutter actors, so doing so after
window actors were already cleaned up should not be a problem, as this
was the case before too.

When switching between the existence and not of a stage ClutterGrab, we
would correctly attempt to synchronize key focus from the perspective of
the Wayland clients.
But this synchronization should do its own checks about existing stage
grabs before determining a client window has key focus or not.
Add that check, so that grabs correctly unfocus the keyboard in Wayland
clients, in addition to pointers and touch.

For wayland meta_window_move_to_monitor sends a configure to the client
without actually moving the window, yet and the
meta_display_queue_check_fullscreen call won't detect any changes.
Checking for fullscreen in meta_window_update_monitor fixes the problem
because it is called whenever the window actually changed the monitor it
is on.

We use meta_workpace_focus_default_window() to sync the input focus back
to a window after it was on shell UI, this is not really necessary on
Wayland, but it is on X11. What this function does internally is ask
MetaWindowStack about the topmost window and focus+raise that window.
In gnome-shell we set the input focus to the default window every time
the key-focus changes to NULL (see shell-global.c ->
sync_stage_window_focus()). Now when closing the alt-tab switcher and
activating a window while there's an always-on-top window on the
workspace, meta_workspace_focus_default_window() will focus that
always-on-top window right after closing the alt-tab switcher, making it
impossible to focus another window using alt-tab.
To fix this, make meta_workspace_focus_default_window() check if there's
an existing focus_window first, if there is, use that, and if there
isn't, resort to just focusing the topmost one.

We use get_window_for_event() to check whether an event happened on top
of a window or on top of shell UI to decide whether to bypass delivering
the event to Clutter. In case of crossing events though, we can't just
use the device actor to determine whether to forward the event to
Clutter or not: We do want to forward CLUTTER_LEAVE events which
happened on top of shell UI. In that case the device actor is already a
window actor (the pointer already is on top of a window), but the shell
still needs to get the LEAVE crossing event.
Since the event source actor got removed from the detail of
ClutterEvent, the context we're looking for (which actor did the pointer
leave) is now the target actor that the event gets emitted to. Since the
last commit, we also made event filters aware of this context by passing
the target actor to them, so use this context now to determine whether
we're on top of a window or not.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2321>
We'll need the additional context of which actor the event will be
emitted to in mutters event filter (see next commit), so pass that
target actor to the event filters that are installed.

We'd guess the initial monitor before it was actually calculated by
looking at the initial geometry. For Wayland windows, this geometry was
always 0x0+0+0, thus the selected monitor was always the primary one.
This is problematic if we want to provide initial more likely
configurations to Wayland clients. While we're not doing that yet, it'll
be added later, and this is in preparation for that.

This will later be used to tell Wayland clients about a size they
shouldn't exceed.
If the window doesn't have a main monitor, this function does nothing
and returns FALSE.

Since the introduction of ClutterGrabs, MetaDnd now no longer gets
notified about input events on the stage during grabs (for example while
the alt-tab popup is shown) and thus can't move the grab feedback actor
anymore.
To fix this, forward events to MetaDnD directly from
meta_display_handle_event() when a ClutterGrab is in effect.

We get the MetaWaylandCompositor a bunch of times, but we can do with
getting it only once and then also replace the is_wayland_compositor()
checks with a if (wayland_compositor).

When generating the action label, we expect both directions of these
features to have consistent settings (either both get a keycombo, or
they don't) or these just return NULL altogether.
Since one of the directions has an action associated, this is
misleading, so be more lenient at the time of generating the action
label.

meta_window_(un)queue() was implemented with global arrays in window.c
that managed MetaLater handle IDs and lists of window queues. In order
to rely less on scattered static variables and making it clearer that
we're dealing with per display window management and not something
specific to a single window, move the window resize/calc-showing queue
management to MetaDisplay.

It's still used by e.g. GNOME Shell to produce fallback icons for X11
applications that doesn't come with a .desktop file. Geometry stays in
the generic class because it's used for minimize animations and is
configured by the panel (e.g. the one in gnome-shell-extensions).

The comments in this function tells a story of C programmer self
reflecting about data types and Perl. While that can be nice, the rest
consisted mostly of repeating what the code line below did, with the end
result being that the function didn't fit on screen, resulting in worse
readability overall.

There may be situations where we may stack a ClutterGrab on top of a
wayland popup's. Since ClutterGrab should win over client grabs, we
mostly correctly figure out that it should start doing
bypass_wayland=TRUE and bypass_clutter=FALSE while the ClutterGrab
holds, however the late checks for the MetaDisplay event route can
still toggle bypass_clutter on, resulting in neither handling events.
This check for wayland popups in the display event route should just
enforce wayland handling if wayland is meant to be receiving events,
so ensure these don't mix together.

Wayland event processing and WM operations are themselves outside the
ClutterGrab loop so far. Until this is sorted out, these pieces of
event handling have got to learn to stay aside while there is a
ClutterGrab going on.
So, synchronize foci and other state when grabs come in or out, and
make it sure that Wayland event processing does not happen while
grabs happen.
