Add a helper function that ensures any queued virtual input events have
been flushed from the input thread. This works by posting a task to the
input thread, which will itself queue another callback back to the main
thread. Once the main thread callback is invoked, the flush call is
unblocked and the function returns. Upon this, any previously emitted
virtual input event should have already passed through the input thread
back into the main thread, however not necessarily fully processed.
For making sure it has been processed, one also have to make sure the
stage has been updated, e.g. via `meta_wait_for_paint()`.

The test does simply "wait" which apparently is not enough to ensure the
client window did resize to the expected dimensions. Use "wait_reconfigure"
and assert that the size after resize is the expected, before going further
at testing its behavior after maximize/unmaximize; it might end up with the
unexpected size after the whole operation.

We put a DEVICE_ADDED or DEVICE_REMOVED event into Clutters event queue
here, so we should also wait for Clutter to process events once.
Just putting an event into the queue doesn't mean it gets processed
immediately (especially when the commit after this one is applied), so
wait for a stage update here.

If two X11 windows were the last two, we'd remove them from the stack
while unmanaging them. That'd hit an assert in
meta_stack_tracker_restack_managed(), resulting in the following crash
when Xwayland exited unexpectedly with two or more X11 windows being the
only windows on the stack:

The added test specifically checks that this scenario is handled
gracefully.

Instead of having users of the test client manually deal with alarm
filters, let the test client automatically add itself as filters. This
changes the MetaX11Display a bit, to handle an array of filters instead
of a single filter.

Fullscreen Wayland toplevel surfaces don't need to respect the
configured size in which case the window content get centered on a black
background which covers the whole monitor.

Make sure that if we wiggle a scan-out capable surface a bit, it won't
scan out if it's not exactly in the right position. Do this by first
making the window not fullscreen, then moving it back and forth,
verifying the correct scanout state for each presented frame.
This test addition reproduces the issue described in
https://gitlab.gnome.org/GNOME/mutter/-/issues/2387.

Gnome-shell uses meta_display_focus_default_window() when shell elements
loose focus which is the case with Alt+Tab window switching. Globally
active input clients don't immediately gain focus though so if
meta_display_focus_default_window focuses a wrong window stacking and
focus don't behave as expected.

New commands to set the number of workspaces, activate a workspace, with

This is an old relic from when ClutterStageView was being added, and
tests were somewhat prepared to be able to test the "X11 style" of
things, with the nested backend some how managing to emulate that.
Lets drop that stuff, it isn't used by the test suite, and isn't useful
anyway; if we want to test X11 configurations, we should use the actual
X11 backend, which didn't make use of this anyway.

This adds a copy of the calibration test profile and sets up a test to
first add it as a system profile, then setting up the XDG_DATA_HOME
directory so that the duplicate profile is detected, added, and later
discarded.

The D-Bus runner used by tests, including installed tests, is made to be
reusable from GNOME Shell. To do this, install it and the templates in
the pkgdatadir (e.g. /usr/share/mutter-APIVERSION/tests/), generate a
custom runner for the installed tests that uses the installed script and
templates, and change the non-installed original runner to use the
non-installed templates.
The end goal is to reuse the D-Bus session runner and templates used for
mutter when test running GNOME Shell.

This allows using two separate ICC profiles for one "color profile",
which is necessary to properly support color transform
calibration profiles from an EFI variable.
These types of profiles are intended to be applied using the color
transformation matrix (CTM) property on the output, which makes the
presented output match sRGB. In order to avoid color profile aware
clients making the wrong assumption, we must set the profile exposed
externally to be what is the expected perceived result, i.e. sRGB, while
still applying CTM from the real ICC profile.
The separation is done by introducing a MetaColorCalibration struct,
that is filled with relevant data. For profiles coming from EFI, a
created profile is practically an sRGB one, but the calibration data
comes from EFI, while for other profiles, the calibration data and the
ICC profile itself come from the same source.

This mocks gsd-colord to enable night ligth at a given temperature. The
test then verifies that the result exactly matches that of the gamma
ramps gsd-color generated for the same temperature and ICC profile.
There are two types of profiles tested; ones with VCGT, i.e. calibrated
profiles, and ones without. These are tested as the VCGT affects how the
gamma curve looks, while the non-VCGT profiles all only rely on
the blackbody temperature to generate a gamma ramp.

We created device profiles, that we manage the lifetime of in colord,
but color devices can be assigned profiles other than the ones it was
created for. For example, this can include the standard sRGB profile
provided by colord.
To achieve this, keep track of the default profile of the CdDevice as
the "assigned" color profile of the device. Given this profile
(CdProfile), construct a MetaColorProfile that can then be interacted
with as if it was generated by ourself.
The assigned profile (default profile in colord terms) does nothing
special so far, but will later be used to determine how to apply CRTC
gamma ramps etc.
The sRGB.icc file used in the tests was copied from colord. It was
stated in the repository that it has no known copyright restrictions.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
Just as gsd-color does, generate color profiles. This can either be done
from EFI, if available and the color device is associated with a built
in panel, or from the EDID. If no source for a profile is found, none is
created.
The ICC profiles are also stored on disk so that they can be read by
e.g. colord. The on disk stored profiles will only be used for storing,
not reading the profiles, as the autogenerated ones will no matter what
always be loaded to verify the on disk profiles are up to date. If a on
disk profile is not, it will be replaced. This is so that fixes or
improvements to the profile generation will be made available despite
having run an older version earlier.
After generating, add some metadata about the generated file itself
needed by colord, i.e. file MD5 checksum and the file path.

Tests that test case EDID is setup correctly, and that color devices for
monitors are created.
tests/color: Add hotplugging tests
Checks that changing the number of connected monitors reflects the
number of current color devices, and that we end up with the correct end
state.

gsd-color provides this API, which exposes details about the night light
state. Currently, gsd-color also turns this state into CRTC gamma
changes, but this will eventually change, and this is a preparation for
this.
The proxy isn't yet used for anything.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
This will be needed for adding colord integration without breaking
testing.
The test context is altered to make sure any left over color devices are
cleaned up before starting. This means it becomes possible to run a test
case multiple times without having to restart meta-dbus-runner.py.
Note: Don't use os.getlogin() to get the current username; as that
requires a controlling terminal.

We fairly consistently had multiple monitors with the whole
vendor,product,serial tuple identical. If we start relying on making
monitors a bit more unique, e.g. for colord integration, we need to make
two monitors connected distinguishable in order for tests to properly
reflect reality and excercise the correct colord integration paths.

Client connections may linger after the test driver is teared down;
handle this gracefully by unsetting the user data on the wl_resource,
and make the resource destructor a no-op, instead of where it would
otherwise remove itself from the resource list. This fixes this crash
