'screen-cast/monitor-src: Use clutter_stage_paint_to_buffer'
(6c818cd8d5) made the non-dma-buf path use
clutter_stage_paint_to_buffer() to avoid running into direct scanout
issues. At a glance, the dma-buf paths didn't have the same issue since
it explicitly handled dma-bufs by blitting them.
What it also did was move the recording to an idle callback, to avoid
paint reentry issues. A side effect of this, however, is that it also
broke the dma-buf paths, as they rely on the back buffer existing, and
the stage view direct scanout already being setup, which it isn't in an
idle callback.
Fix this by using the dma-buf variant of
clutter_stage_paint_to_buffer(): clutter_stage_paint_to_framebuffer().
This has some negative performance impact, but we can't use
cogl_blit_framebuffer() when using an idle callback for recording.
Potential performance improvements to make things work more as they did
before is to enhance 'cogl_blit_framebuffer()' a bit, making it a vfunc
that could be implemented by MetaOnscreenNative. A flag to say whether
to look at the back or front buffer would let MetaOnscreenNative know
whether to use the already committed-to-KMS buffer, or the current back
buffer.

The MetaKeyboardA11yFlags are used by gnome-shell to show a dialog
whenever a keyboard accessibility feature is switched using the
keyboard.
Unfortunately, commit c3acaeb25 renamed the Clutter flag to Meta and
moved them to a private header. As a result, gnome-shell do not show any
dialog anymore when a keyboard accessibility feature is activated.
Move the MetaKeyboardA11yFlags definition to a public header so that
gnome-shell can use it.

The min distance to the right/bottom edge depends on Wayland concepts

Updating the PropTable has the side effect that the parse callback now
also gets called on hotplug but it is used to initialize data. The parse
callbacks are moved to the read_state functions which are aware if this
is an initializing call or just an update.

* creating an actor will result in it being assigned a color state
with the color space sRGB
* creating an actor with a color state passed will result in that
color state being returned
* changing an actor's color state makes that happen
* changing an actor's color state to NULL ends up with it being
changed back to a color state with the sRGB color space

ClutterColorState, that is a GObject. each ClutterActor would own
such an object, and it'd be set via a GObject property.
It would have an API to get the colorspace, whether the actor
content is in pq or not, and things like that.
if it is NULL, it will default to color state with sRGB colorspace.

There are no 'features' left, the last one, GLSL shader support, was
moved to Cogl.
This also move the Cogl context creation to a more sensible place, as it
was hidden away in the feature initialization.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2015>
The Cogl feature was removed a while back, while Clutter just hard coded
it to TRUE. Lets remove the confusion that GLSL isn't supported and just
remove the (dead) fallback paths.

Add `sync_effects_completed()` and `verify_view()` in
order to allow Wayland test clients to trigger verifications
and add convenience functions to use them to client-utils.
Notes:
- `sync_effects_completed()` works in two stages in order
to ensure it doesn't race with window effects. By the time
`sync_effects_completed()` is processed, an effect could
already have ended or not yet been scheduled. Thus we
defer a check for pending effects to the next paint cycle,
assuming that by then they should have been scheduled.
- `meta_ref_test_verify_view()` internally triggers the
`paint` signal for the stage which is why it can not be run
in the after-paint signal handler.

Our internal interpretation of output transforms is not in line with
the Wayland spec. Wayland describes them as the transform that a
compositor will apply to a surface to compensate for the rotation
or mirroring of an output device - counter-clockwise.
Mutter in turn interprets it the other way around. One could
argue it does the same but clock-wise - or it interprets the transform
from the viewpoint of the content, not the device.
In either way, the difference is that 90 and 270 degree values are
switched. Thus swap these accordingly when we translate from
`WL_OUTPUT_TRANSFORM` to `META_MONITOR_TRANSFORM`.

This launches Xvfb, using xvfb-run, and inside tests the following:
1. Launching 'mutter --x11' works
2. Launching a couple of X11 clients works (doesn't crash or result in
warnings)
3. Launching 'mutter --x11 --replace' works
4. Terminating works
It does this using a simple shell script.

We don't make use of the refresh rate in any useful way in the X11, and
in this case we just ended up with warnings since the refresh rate was
NaN. Fix this by making it 0.0 to mean "no refresh rate". This also is
what 'xrandr' itself reports.

This adds a minimalistic fullscreen direct scanout test case, that runs
on vkms. It doesn't use EGL, and it uses uninitialized memory, thus it
lacks any kind of implicit synchronization, but it does test that the
scanout selection paths are working.
What is tested is:
* DMA buffer allocated using gbm on top of VKMS
* Buffer passes a mode setting TEST_ONLY check
* Paint is omitted
* Correct buffer active in KMS after presentation
What isn't yet tested:
* Implicit synchronization related behavior
* Presented pixel content

They're just typedefs to CoglObject and CoglObjectClass, respectively,
and the latter is unused already. The former is used in a couple of
deprecated headers, which can easily be changed.

There is no need to make CoglJournal a CoglObject, nor any kind of
object for that matter, since it doesn't require refcounting at all.
CoglJournal is entirely private to, and managed by, CoglFramebuffer,
and it only needs to create and destroy it.
Make CoglJournal a free-form struct, and adjust CoglFramebuffer to
call _cogl_journal_free() instead of cogl_object_unref().
