Scaling values computation code served us well in the past years but
it's quite delicate and it has some issues in edge cases, so add a test
that verifies that the computed scaling values for all the most common
resolutions (and some that may be common in future) are what we expect
to be.
This may also serve us in future when we'd define a better algorithm to
compute the preferred scale, but this not the day.

We'll have two persistent client connections alive for the whole test,
one X11 client, and one Wayland client. So in order to be able to set up
the async waiter, do so after setting up the X11 client, as after that
we know we'll have a MetaX11Display ready to use.

While multiple built-in panels isn't actually supported in any
meaningful manner, if we would ever end up with such a situation, e.g.
due to kernel bugs[0], we shouldn't crash when trying to set an
'external only' without any external monitors.
While we could handle this with more degraded functionality (e.g. don't
support the 'switch' method of monitor configuration at all), handle it
by simply not trying to switch to external-only when there are no,
according to the kernel, external monitors available. This would e.g.
still allow betwene 'mirror-all', and 'linear' switches.
The crash itself was disguised as an arbitrary X11 BadValue error, due
to mutter trying to resize the root window to 0x0, as the monitor
configuration that was applied consisted of zero logical monitors, thus
was effectively empty.

It's very useful to have common functions for easily creating a monitor
test setup for all kinds of tests, so move create_monitor_test_setup()
and check_monitor_configuration() and all the structs those are using to
monitor-test-utils.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1243
check_monitor_test_clients_state() is a function that's only meant to be
used in the monitor-unit-tests, and since we're going to move the
functions for creating MonitorTestSetups into a common file, this
function is going to be in the way of that. So move the checking of the
test client state outside of check_monitor_test_clients_state().
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1243
We're going to move the functions for building MonitorTestSetups to the
common monitor-test-utils.c file.
To make building test setups a bit more straightforward in case no
TestCaseExpect is wanted, change create_monitor_test_setup() to take a
MonitorTestCaseSetup instead of a MonitorTestCase as an argument.

Previously the tile coordinate was used to offset a CRTC scanout
coordinate within a larger framebuffer. Since 3.36 we're always
scanning out from (0, 0) as we always have one framebuffer per CRTC; we
instead use the tile coordinate to calculate the coordinate the tile has
in the stage view. Adapt calculation to fulfil this promise instead of
the old one.
This also corrects the tiled custom monitor test case.

It might not be available right on initialization time if X11 is started
asynchronously. As this is a requirement for our tests, ensure it is there
before proceeding with the test.

To make it more reliable to distinguish between values that are read
from the backend implementation (which is likely to be irrelevant for
anything but the backend implementation), split out those values (e.g.
layout).
This changes the meaning of what was MetaCrtc::rect, to a
MetaCrtcConfig::layout which is the layout the CRTC has in the global
coordinate space.

This test forgot to specify the existing CRTC routings in the setup. For the
first output the default 0 was ok, now it is -1 to ensure that the code will
assign it correctly. For the second output the default 0 was incorrect, because
possible_crtcs does not include 0. Now that CRTC is initialized to off
instead, because the second output is hotplugged later and running a CRTC
without an output does not make sense.
This fix will keep this test passing when a future patch attempts to preserve
existing CRTC routings. Assuming that any existing routing is valid, such
routing will be kept. In this test case the existing routing was illegal, it
should have been impossible, which then causes that future patch to fail the
test by assigning the wrong CRTC.

We already ran a Wayland client to test various Wayland paths. What was
missing to also run a X11 client was to hook in the X11 async waiter
wires, so do that and run both types of clients.

Rather than handle UpClient in both MetaBackend (to reset the idletime
when the lid is opened), and in MetaMonitorManager and
MetaMonitorConfigManager (to turn the screen under the lid on/off
depending on its status), move the ability to get the lid status from
UPower or mock it in one place, in MetaBackend.
Changing the test monitor managers ability to rotate CRTCs in one test
affected the next test. Avoid leaking such state by resetting it before
each test. To continue passing, some tests needed to be updated
regarding to still pass.
https://bugzilla.gnome.org/show_bug.cgi?id=788915
Add a test case that checks that we don't try to revert to a
laptop-panel-only configuration after closing the lid after an external
monitor is connected.

Check that if there are multiple modes with the same ID (resolution,
refresh rate and handled flags) we correctly add the preferred mode to
the list of monitor modes.

In order to eventually support multilpe GPUs with their own connectors,
split out related meta data management (i.e. outputs, CRTCs and CRTC
modes) into a new MetaGpu GObject.
The Xrandr backend always assumes there is always only a single "GPU" as
the GPU is abstracted by the X server; only the native backend (aside
from the test backend) will eventually see more than one GPU.
The Xrandr backend still moves some management to MetaGpuXrandr, in
order to behave more similarly to the KMS counterparts.

Convert MetaCrtcMode from a plain struct to a GObject. This changes the
storage format, and also the API, as the API was dependent on the
storage format.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
Turn MetaCrtc into a GObject and move it to a separate file. This
changes the storage format, resulting in changing the API for accessing
MetaCrtcs from using an array, to using a GList.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
Turn MetaOutput into a GObject and move it to a separate file. This
changes the storage format, resulting in changing the API for accessing
MetaOutputs from using an array, to using a GList.

Check that configurations where monitors are disabled are properly
used. Also test that old configurations with explicitly disabled
outputs are migrated properly.

Give clients (such as Xwayland) a chance to bind the wl_output global
before we continue, otherwise there is an significant risk that mutter
won't see the bind request until after the next hot plug which might
have destroyed the global object.

The foreach CRTC monitor mode helper incorrectly iterated over outputs
without CRTC when non-tiled modes were set on tiled monitors. This was
not expected by callers, so fix the helper to only iterate over active
outputs (that has or should have a CRTC).
The test cases uses the incorrect behaviour of the foreach CRTC helper
to check that the disabled outputs mode are set to NULL, so add a
foreach output helper and change the tests to use that instead.

When headless, we don't have any logical monitors to derive a screen
size from, but we can't set it to empty as that will cause issues with
the clutter stage, UI widget layout and other things. To avoid such
issues, just fall back to a 640 x 480 screen size when headless.
