Hides libdisplay-info under a build time default-off flag,
provides provision to parse essential edid parameters with
APIs provided by libdisplay-info. This implementaion increases
readibility, avoids code duplication and decreases complexity
of edid parsing.

This ATM triggers missed .commit events for the window in question,
to be addressed in Xwayland. Since the test does not seem to specifically
rely on this window being CSD, make it a regular window instead.

This will be used to extract the resolution and refresh rate from
strings like "1920x1080@60.0" or "1280x720". This aims to replace the
use of the locale dependent sscanf() function.

Otherwise we'll have a cursor sprite backed by a surface that no longer
exist. This usually doesn't happen, but can happen in rare situations
related to pointer capability changes Wayland client cursor changes and
hotplugs.

We have the drm/InfoFrame encoding and our MetaOutputHdrMetadata
encoding. Check that we can correctly convert between each other by
doing a encode/decode and decode/encode roundtrip and then checking for
equality.

We relied on them being valid longer to keep track of used GPUs. If we
don't have the CRTC (or output) we don't have a way to fetch the pointer
to the MetaGpu that drives the associated monitor.
This avoids a crash when trying to fetch said pointer from what would be
the NULL MetaCrtc pointer.

We want to avoid using too high scales too easily, which started to
happen 2f1dd049bf ("monitor-manager: Rework default scale factor
selection"). Instead of using the closest non-fractional scale, which
effectively is what we'd do, only round upwards if we're closer than
0.25 (25%).
Since there are some wiggle room for scales to make the logical
resolution on the integer pixel grid, make sure to compensate. This
compensation is done by adding an extra 0.2 to scale difference.
For example the following fractional scales will get these corresponding
integer scales:
* 1.25 -> 1.0
* 1.5 -> 1.0
* 1.75 -> 2.0
* 2.0 -> 2.0
* 2.50 -> 2.0

Instead of testing headless start using the dummy backend, do so with
the real native backend, and use the drm-mock library instead to emulate
monitors being disconnected at startup.

This new filter allows test cases to manipulate what the kernel reports,
e.g. mark connected connectors as disconnected to emulate monitors
connecting and disconnecting.

In order to make things more and more asynchronus and to each time we
paint be an isolated event, that can be potentially be applied
individually or together with other updates, make it so that each time
we draw, we use the transient MetaFrameNative (ClutterFrame) instance to
carry a KMS update for us.
For this to work, we also need to restructure how we apply mode sets.
Previously we'd amend the same KMS update each frame during mode set,
then after the last CRTC was composited, we'd apply the update that
contained updates for all CRTC.
Now each CRTC has its own KMS update, and instead we put them in a per
device table, and whenever we finished painting, we'll merge the new
update into any existing one, and then finally once all CRTCs have been
composited, we'll apply an update that contains all the mode sets for all
relevant CRTCs on a device.

Add a tiny library that sabotages errors in drmMode*() API calls. This
will be used to artificially trigger arbitrary errors, e.g. cause the
next commit to fail with EBUSY.
The three mocked methods are added as they will be used in a future
commit.

At first it was called seal(), but then updates could be amended after
being posted, given a flag. That flag has been removed, so we can go
back to sealing, since it's once again acts more as a seal.

If we call schedule(), which will schedule an update some time in the
future, and then schedule_now(), we should reschedule the frame clock to
update immediately, and not some time in the future.

This is intended to be used only for plane assignment, and CRTC like
changes, so that one can e.g. change a cursor plane on a pending update
that changes the primary plane, before it has been committed to KMS.
The kms-updates test overrides the get-state function MetaKmsCrtc. This
is needd to not have the update mechanism not clamp the gamma size to 0,
as vkms reports the gamma length 0. By pretending it's 3, we can test a
simple and small gamma lut is merged correctly when merging updates.

This protocol is intended to let special clients create transient-for
relationships between X11 and Wayland windows. The client that needs
this is xdg-desktop-portal-gnome, which will create e.g. file chooser
Wayland dialogs that should be mapped on top of X11 windows.
