New add_monitor command for adding secondary monitors. Support setting
the workspaces-only-on-primary preference.
The stacking test tests the focus and stacking for multiple monitors
with workspaces-only-on-primary=true. The default_focus changes
previously broke this.

bind_output() creates output interface resource, but does not
set implementation for it when wayland_output->monitor is NULL.
However, when the wayland library is running wl_closure_invoke(),
it expects the implementation to be non-NULL, and if not, it just
segfaults mutter by NULL pointer dereference.
This commit tries to address this issue by setting an implementation
when wayland_output->monitor is NULL. This could help prevent crash
when resuming from suspend or hotplugging displays.

The order of dependencies influences the order of -L arguments to gcc/ld,
we should put our private library first, so that introspection prefers
looking up libraries in private paths than public ones.
This could bring problems in API updates of the libmutter-test library,
since introspection would still prefer the old installed one.

ClutterActions now no longer receive their events via
clutter_actor_event(), instead they get special treatment by the stage
now. Make the MetaGestureTracker work with this and stop emitting events
directly to Clutter via clutter_actor_event(), but instead let them get
through to Clutter (but still not to Wayland).

Since the last commit, ClutterStage automatically cancels an implicit
grab (including all its ClutterActions) when a conflicting ClutterGrab
appears.
This means we no longer have to look out for GRAB_NOTIFY crossings in
ClutterGestureAction and can instead depend on the sequence_cancelled()
vfunc for this.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
A ClutterGrab takes precedence over implicit grabs, so when one happens,
let's check which part of the implicit grab tree is inside the new
ClutterGrab. Cancel and remove the parts which aren't, and if nothing
is in there anymore, cancel the whole implicit grab.
Emitting crossing events correctly here is getting quite tricky:
- When the implicit grab didn't get cancelled by the ClutterGrab, we
simply want to emit all GRAB_NOTIFY crossings to the implicit grab, as
we do with all other crossings.
- When the implicit grab did get cancelled and the new ClutterGrab wants
to emit ENTER crossings, we want those to be emitted to the actual
targets, so cancel the implicit grab before emission.
- In the last case where the implicit grab did get cancelled and the new
ClutterGrab wants to emit LEAVE crossings, those should be emitted to
the implicit grab again, so we cancel the grab only after the emission
of those.

Now that we have two kinds of grabs, the intricacies of event delivery
got slightly more complicated. So this seems like a good point to
introduce a new GRABS debug flag that gives an overview of which grabs
are currently in effect.

We're almost there, everything is in place to notify ClutterActions
about a sequence getting pulled away under its feet.
The only thing that's missing is the actual notification to actions now,
so let's do that.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
Another baby step just like the last commit: This commit takes care of
the opposite case: An action handling a sequence event stops further
emission of events to actors.
Since sequences remain around for longer than the context of just a
single event, it makes sense to provide a way to "claim" those sequences
even when outside of event handling context, so introduce API for that.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
As soon as any event of a sequence is handles/stopped during emission,
all actors and actions that would have gotten to see it afterwards have
a big problem: If that event was a TOUCH_END event, the actor/action is
forever going to think that this touch is still active.
For ClutterActions, we're going to handle this by introducing a way to
send them a notification when stuff like this happens.
As a baby step towards all that, make event emission exclusive to actors
as soon as any actor stopped an event.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
We'll soon introduce a new gesture tracking framework which heavily
depends on ClutterActions seeing all events of a sequence. For this to
work, a larger change to event delivery is needed: Implicit grabbing of
all events for button and touch press->motion->release sequences to
ensure ClutterActions continue receiving events for the whole sequence.
This commit takes care of that: At the start of an event sequence we
collect all the event-handling actors and actions to a GArray that lives
in the PointerDeviceEntry, and then deliver all events belonging to
that sequence to the same actors/actions until the sequence ends.
To avoid events getting pulled from under our feet when mutters event
filter returns CLUTTER_EVENT_STOP, this also introduces private API
(maybe_lost_implicit_grab()) on ClutterStage so that we can't end up
with stale sequences.
Note that this also slightly changes behavior when it comes to event
delivery to actions: Because we now store actions separated from their
actors, any action returning CLUTTER_EVENT_STOP now stops event
propagation immediately. That was different before, where we'd emit
events to all actions of the actor and only then stop propagation.
Note that this isn't handling ClutterGrabs correctly right now,
this will be a little tricky, so we'll take care of that in a future
commit.
To handle actors getting destroyed or unmapped during a grab, listen to
notify::grab on the deepmost actor in the implicit grab tree. This gives
us a notification when any actor inside the tree goes unmapped.

A fairly small refactor, move the emission of events to actions from
clutter_actor_event() to stage level.
We do this because in the future we'll need to know on stage level
whether events were handled by an actor or by an action.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
_clutter_actor_handle_event() currently allocates a new GPtrArray on the
heap for every single event emission, let's avoid this by keeping an
array around in ClutterStage and reusing that.
This is moving the last few bits of event emission into ClutterStage,
which will be useful when we introduce implicit grabbing in subsequent
commits.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
There's no real reason to keep those events exclusive to the stage, some
actors or actions might want to get notified about proximity events too,
so propagate them like any other event.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
Right now and due to loads of refactorings lately, the event emission
paths are a bit cluttered (ha ha ha) around in Clutter. For example the
event target actor gets set in clutter-main.c, but event emission is
actually managed by ClutterStage these days.
Since we'll introduce implicit grabbing of touch/button-press sequences
soon, let's shuffle things around a bit to make that easier:
Move event emission to the stage, it now gets a ClutterEvent without any
extra context like the target actor from clutter-main. The stage then
looks up the target actor itself and emits the event to the appropriate
actors in the scenegraph. A special path is introduced for emitting
crossing events, because here the event-receiving actors don't follow
the "capture+bubble from pointer actor to grab actor" rule.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2342>
Crossing events should never be stopped during event emission. We
already have a check that enforces this in clutter_actor_event(), but
ClutterActions still sometimes try to stop crossing events from
propagating.
Improve that situation and return CLUTTER_EVENT_PROPAGATE when handling
crossings in ClutterActions, too.

The previous logic tried to keep the position of the top left corner of
the window relative to the top left corner of the monitor. This allowed
the window to move out of the target monitor. This change keeps the
proportions of the distance between the window and the monitor borders
instead if possible. Otherwise it keeps the relative position of the
center of the window clamped to [0,1] to make sure the window lands on
the right output.
This also slightly changes what monitor is considered to be on: the
monitor which contains the center of the window and, if the center is on
no monitor, the monitor wich overlaps the most with the window.

This partly reverts f9857cb8 but leaves an exception for cursor

So we can remove the additional `next_fb` and `current_fb` pointers from
`MetaOnscreenNativeSecondaryGpuState`.
Some non-scanout buffers also need to be held in the case of GL blitting
which completes in the background. Those are referenced from the scanout
buffers themselves to ensure the source buffers live just as long.

There's still a possibility that some events remain within the
`ClutterMainContext` when it's being unref-ed for the last time (as seen
on asan logs). Make sure they get freed by using
`g_async_queue_new_full()` and specifying the appropriate destroy
function.

Calculating a timestamp from the past distorts the dispatch lateness
calculation, leading to an inflated max_render_time, which again
increases the likelyhood of next_update_time being in the past.

As with GAMMA_LUT, track whether privacy screen state has been pushed to
KMS in the onscreen. This leaves MetaOutput and MetaCrtc to be about

As with CRTC GAMMA_LUT, we're moving towards making the entity managing
KMS updates aware if there are any changes to be made, and whether KMS
updates are actually needed or not, and for privacy screen changes, this
means we need to communicate whether the privacy screen state is valid
or not. This allows the caller to create any needed MetaKmsUpdate.
