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.
The qemu machine is configured to use 256M of memory, as the default
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.

VT switching, which in preparation is only allowed on the 'default'

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
send yet another invalid geometry the second time, we log one time too

second configure event; it's enough to pass through the error handling
path once.

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
mocked service would stay alive, and the test case being run eventually
failing due to a timeout, not the failure itself.

teared down.
This avoids the dead lock, while still printing the appropriate error

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.

Create a test system bus and use it to run all the tests, add a mock
SensorsProxy (via dbusmock template) server that implements the

To make testing easier, the service is created on request of a proxy for

This is done using a further mock service that is used to manage the
others, using python-dbusmock to simplify the handling.
Add basic tests for the orientation manager.
As per the usage dbusmock, we're now launching all the tests under such

When we get an orientation event we don't care about keeping track of the
configuration changes, but actually we can consider the new configuration
just a variant of the previous one, adapted to floating device hardware
events, so we only want to apply it if possible, but we don't want to keep
a record of it for reverting capabilities.
Doing that would in fact, break the ability of reverting back to an actual
temporary or persistent configuration.
For example when device orientation events happen while we're waiting for
an user resolution change confirmation, we would save our new rotated
configuration in the history, making then impossible to revert back to
the original persistent one.
So in such case, don't keep track of those configurations in the history,
but only keep track of the last one as current, checking whether the
new current is child or sibling of the previously one.

With some resolutions (such as 4096x2160) we may compute duplicated
scale factors because we used a too wide threshold to check for an
applicable value.
In fact, while when we're at the first and last values it's fine to
search applicable values up to SCALE_FACTORS_STEP, on intermediate ones
we should stop in the middle of it, or we're end up overlapping the
previous scaling value domain.
In the said example in fact we were returning 2.666667 both when
looking to a scaling value close to 2.75 and 3.00 as the upper bound of
2.75 (3.0) was overlapping with the lower bound of 3.0 (2.75).
With the current code, the lower and upper bounds will be instead 2.875.
Adapt test to this, and this allows to also ensure that we're always
returning a sorted and unique list of scales (which is useful as also
g-c-c can ensure that this is true).
