249274c677 clutter/actor: Pass stage as user_data when unrealizing
We can avoid having to get the stage again for every child of the
subtree we're unrealizing by getting the stage once and passing it as
user_data to the callbacks.

ae83a61e67 clutter/actor: Remove actors from shallow relayout list when unrealizing
With the introduction of the shallow relayout mechanism another small
but severe regression sneaked into our layout machinery: We might
allocate an actor twice during the same allocation cycle, with one
allocation happening using the wrong parent.

This issue happens when reparenting an actor from a NO_LAYOUT parent to
a non-NO_LAYOUT parent, in particular it triggered a bug in gnome-shell
when DND reparents a child from the NO_LAYOUT uiGroup to the overviews
Workspace actor after a drag ended. The reason the issue happens is the
following chain of events:

1. child of a NO_LAYOUT parent queues a relayout, this child is added to
the priv->pending_relayouts list maintained by ClutterStage

2. child is reparented to a different parent which doesn't have the
NO_LAYOUT flag set, another relayout is queued, this time a different
actor is added to the priv->pending_relayouts list

3. the relayout happens and we go through the pending_relayouts list
backwards, that means the correct relayout queued during 2. happens
first, then the old one happens and we simply call
clutter_actor_allocate_preferred_size() on the actor, that allocation
overrides the other, correct one.

So fix that issue by adding a method to ClutterStage which removes
actors from the pending_relayouts list again and call this method as
soon as an actor with a NO_LAYOUT parent is detached from the stage.

With that in place, we can also remove the check whether an actor is
still on stage while looping through pending_relayouts. In case
something else is going wrong and the actor is not on stage,
clutter_actor_allocate() will warn anyway.

5b0a7b3a33 clutter/timeline: Wait for stage if no frame clock is available
When picking which frame clock to use, we traverse up in the actor
hierarchy until a suitable frame clock is found. ClutterTimeline
also listens to the 'stage-views-changed' to make sure it's always
attached to the correct frame clock.

However, there is one special situation where neither of them would
work: when the stage doesn't have a frame clock yet, and the actor
of the timeline is outside any stage view. When that happens, the
returned frame clock is NULL, and 'stage-views-changed' is never
emitted by the actor.

Monitor the stage for stage view changes when the frame clock is
NULL.

a9a9a0d1c5 clutter: Paint views with individual frame clocks
Replace the default master clock with multiple frame clocks, each
driving its own stage view. As each stage view represents one CRTC, this
means we draw each CRTC with its own designated frame clock,
disconnected from all the others.

For example this means we when using the native backend will never need
to wait for one monitor to vsync before painting another, so e.g. having
a 144 Hz monitor next to a 60 Hz monitor, things including both Wayland
and X11 applications and shell UI will be able to render at the
corresponding monitor refresh rate.

This also changes a warning about missed frames when sending
_NETWM_FRAME_TIMINGS messages to a debug log entry, as it's expected
that we'll start missing frames e.g. when a X11 window (via Xwayland) is
exclusively within a stage view that was not painted, while another one
was, still increasing the global frame clock.

Addititonally, this also requires the X11 window actor to schedule
timeouts for _NET_WM_FRAME_DRAWN/_NET_WM_FRAME_TIMINGS event emitting,
if the actor wasn't on any stage views, as now we'll only get the frame
callbacks on actors when they actually were painted, while in the past,
we'd invoke that vfunc when anything was painted.

2afe3e9223 clutter/stage: Add signals for different update stages
Right now the stage only had a signal called 'after-paint' which was not
tied to painting but updating. Change this to offer 4 signals, for the 4
different stages:

 * before-update - emitted in the beginning before the actual stage
   updating

 * before-paint - emitted before painting if there will be any stage
   painting

 * after-paint - emitted after painting if there was any stage painting

 * after-update - emitted as a last step of updating, no matter whether
   there were any painting or not

Currently there were only one listener, that should only really have
been called if there was any painting, so no changes to listeners are
needed.

847e89d31f clutter/frame-clock: Handle reschedule then dispatch results in idle
A frame clock dispatch doesn't necessarily result in a frame drawn,
meaning we'll end up in the idle state. However, it may be the case that
something still requires another frame, and will in that case have
requested one to be scheduled. In order to not dead lock, try to
reschedule directly if requested after dispatching, if we ended up in
the idle state.

2a6e8bda8d cogl/onscreen: Let swap buffer caller create frame info
We currently have mutter set a global frame counter on the frame info in
the native backend, but in order to do this from clutter, change the
frame info construction from being implicitly done so when swapping
buffers to having the caller create the frame info and passing that to
the swap buffers call.

While this commit doesn't introduce any other changes than the API, the
intention is later to have the caller be able to pass it's own state
(e.g. the global frame count) along with the frame info.

3944daf3c0 clutter/stage: Find devices to update after finish queue redraw
Devices are updated (repicked) as part of the stage update phase, as
their stacking, position and transform might have changed since since
the last update.

The redraw clip was used to avoid unnecessary updating of devices, if
the device in question had it's position outside of the redraw clip. If
the device coordinate was outside of the redraw clip, what was
underneith the device couldn't have changed.

What it failed to do, however, was to update devices if a relayout had
happened in the same update, as it checked the state whether a layout
had happened before attempting to do a relayout, effectively delaying
the device updating to the next update.

This commit changes the behavior to always update the device given the
complete redraw clip caused by all possible relayouts of the same update
as the device update happens in.

ClutterTimeline is adapted to be able to be driven by a

if set, the timeline will add and remove itself to the frame clock
