The following implicit definition for `transform()` did not
correctly apply:
```
a * b = c
c * invert(b) = a
```
Crucially the following did not apply for `FLIPPED-90`
and `FLIPPED-270`:
```
a * invert(a) = identity
```
Fix this by applying the operations, first the flip, then the
rotation, in this order and add tests to ensure correct results
for the requirement above.
Also drop `relative_transform()` as it only had a single user and
can be replaced by `transform()`:
```
invert(a) * b = c
a * c = b
```
As this is not very intuitive, ensure in tests as well.

The test case checks that the stage views of hidden actors are
not updated when the views of the visible outer parent change.
The check for the outer parent's updated stage views currently
relies on ClutterFixedLayout not excluding hidden children in
its size request: As the container doesn't contain any visible
children at that point, its size would change to 0x0 and end
up on no stage view (rather than the assumed two).
Avoid that oddity by giving the outer container a fixed size,
so that the visibility of its child doesn't affect the test
when we fix ClutterFixedLayout.

The test aims to test that trying to fetch X11 clipboard content after
Xwayland went away doesn't cause issues. What happens though is that
sometimes the clipboard content doesn't have time to settle (i.e. fetch
mime types etc) before Xwayland gets terminated, which causes flakyness.
Fix this by waiting for the compositor side clipboard owners to finish
setting up before continuing.

* 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

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.

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

This commit makes it possible to run test executables in a test

with the virtual KMS driver enabled, and a mocked system environment
using meta-dbus-runner.py/python-dbusmock.

128M was not enough for the tests to pass.
Using qemu is also only made possible on x86_64; more changes are needed

any other architecture.

The final tick of a timeline is >= its duration, but when using ticks that
are slightly in the future ("next presentation time") this means the final
tick will execute and complete the timeline up to one frame interval before
the timestamp of that final tick.
For the single clock test we now just check if the overall duration is
within one frame of the expected timeline duration.
The dual clock (switching) test needs a threshold of two frames because
starting each new clock creates a phase shift (error) of up to one frame.

The roundtrip in the handle-configure function could in theory (and in
practice in the future) happen to receive another configure event. If we

We created pipes for the stdout of the spawned mock services. This
resulted in the pipe being filled if enough things were logged, as
nothing was reading from it. Change this to allow for two modes:

(default) - where things are logged directly to /dev/null.

If one would end up with an actor attached to mapped actor, where the
attached actor doesn't itself have an up to date stage view list while
listening on the stage for updating, when clearing the stage views of
the list, anything that would query the stage views list at this time
would end up accessing freed memory.
This could happen if
1) An actor was added to a newly created container actor attached to
the stage
2) The actor got a timeline attached to it
3) The actor was moved to a container that already was mapped
4) A hotplug happened
After (1) both the container and actor would not have any stage views.
After (2) the timeline would listen on the stage for stage views
updates. After (3) the actor would still listen on the stage for stage
views updates. When (4) happened, the actor would be signalled when the
stage got its stage view cleared, at which point it would traverse up
its actor's tree finding an appropriate stage view to base its animation
on. The problem here would be that it'd query the already mapped
container and its yet-to-be-cleared stage view list, resulting in
use-after free, resulting in for example the following backtrace:
0) g_type_check_instance_cast ()
1) CLUTTER_STAGE_VIEW ()
2) clutter_actor_pick_frame_clock ()
3) clutter_actor_pick_frame_clock ()
4) update_frame_clock ()
5) on_frame_clock_actor_stage_views_changed ()
6) g_closure_invoke ()
7) signal_emit_unlocked_R ()
8) g_signal_emit_valist ()
9) g_signal_emit ()
10) clear_stage_views_cb ()
11) _clutter_actor_traverse_depth ()
12) _clutter_actor_traverse ()
13) clutter_actor_clear_stage_views_recursive ()
14) clutter_stage_clear_stage_views ()
...
Avoid this issue by making sure that we don't emit 'stage-views-changed'
signals while the actor tree is in an invalid state. While we now end up
traversing tree twice, it doesn't change the Big-O notation. It has not
been measured whether this has any noticible performance impact.

Previously, we were waiting up to 300ms for the signal, then proceeding
anyway. However, 300ms is not necessarily long enough to wait on an
autobuilder that might be heavily loaded, particularly if it's a non-x86
with different performance characteristics.
Conversely, if mutter responds to the D-Bus signal from the mock sensor
before we have connected to the signal, then we cannot expect to receive
the signal - it was already emitted, but we missed it. In this case, we
need to avoid waiting.
One remaining use of wait_for_orientation_changes() that would previously
always have timed out was in
meta_test_orientation_manager_has_accelerometer(), which does not
actually expect to see an orientation-changed signal. Make this wait
for the accelerometer to be detected instead.

This feature was configured depending on whether the Cogl backend
reported COGL_WINSYS_FEATURE_MULTIPLE_ONSCREEN or not. All cogl backends
do report this, so any code handled the 'static' case were never used.
While we only ever use one stage, it's arguable more correct to
consilidate on the single stage case, but multiple stages is something
that might be desirable for e.g. a remote lock screen, so lets keep this
logic intact.
This has the side effect of completely removing backend features, as
this was the only left-over feature detection that they handled.

When a test failed, an exception would be raised. This meant that the

teared down.

In X11 when we switch to another tty all the the signals are blocked (as
the display fd is not replying back to polling, causing the main loop to
stop), and they are all handled once we switch back to the tty.
This is not a problem for most of external events, but in case of
accelerometer changes, once we reactivate a mutter session we'll get
them all together, causing lots of monitor reconfigurations leading to
black screen for some seconds and most of the times to a wrong
configuration being applied.
To avoid this, batch all these events using an idle to only apply the
last one we got in a loop.
