In some use cases there is a need to dynamically change the preferred
primary GPU, or get rid of the preference altogether. This is currently
not possible due to a change in udev introduced by systemd v247. This
version made the tags "sticky", meaning there is no way to remove them
once attached. When a tag gets removed, only the CURRENT_TAGS property
reflects that change, the removed tag will remain in the TAGS property.
This also bumps libgudev version to 238, since that version introduces
a function, which we need to get the current tags.

This TF can't be defined as a TransferFunction enum because it needs a
gamma_exp value too.
Add to EOTFType enum a new type: EOTF_TYPE_GAMMA.
With this new type, now EOTFs are unions that can have either
a TransferFunction enum or a gamma_exp.
Set gamma_exp as uniform.
Add the support of it in the color management protocol.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4020>
These properties now are tagged unions:
- ClutterColorimetry:
Can be from colorspace or primaries;
- ClutterEOTF:
Can be from known tf or custom gamma exp (next commit);
- ClutterLuminance:
Can be defined explicitly or derived;
Make the color management protocol use them too.

ColorState is inmutable so the GObject properties aren't necessary.
Also move ClutterColorstate and ClutterTransferFunction enums to
color-state.h now that they are not used as GObject properties.

For non-debug and non-plain cases - i.e. mainly release builds.
This ensures we use the same options in all places and draws a cleaner
distinction between g_assert() and g_return_if_fail() - the later will
still be done in release build while the former are meant for debug
only.
One advantage of doing this is that it allows us to use non-trivial
asserts more generously, such as calling `g_list_length()`.

Add a test that:
- Creates 2 clients
- Leases a connector using the first client
- Tries to lease the same connector using the second client
- Checks that the first lease succeeded
- Checks that the second lease failed

Add a test that:
- Creates 2 clients
- Leases a connector using the first client
- Checks that the first client receives a lease_fd event
- Checks that both clients receive a connector withdrawn event
- Finishes the lease
- Check that both clients have access to the connector

Add a test that:

- Checks that an error is raised if a released client is used

Add an event queue to the DRM lease client that allows to check that the
compositor sent the expected events in the expected order.
For the moment, the event queue is used to check that the initial
connection to the compositor works as expected.

Add the most basic possible test that checks that:
- The DRM lease protocol is available
- At least one device is advertised
- At least one connector is available for lease
Organize the code in a way that it is possible to created multiple DRM
lease clients at the same time as future tests will need this.

Add the required files to run DRM lease using the KVM/tty backends.
DRM lease tests need at least one connector available for lease. Instead
of adding the test to "wayland-unit-tests.c", add it to its own file and
set the environment variable MUTTER_DEBUG_LEASE_CONNECTORS=Virtual-1 to
make the only connector created by VKMS by default available for lease.
This commit doesn't add any tests, just the required files to start
adding them.

MetaWaylandDrmLeaseDevice and MetaWaylandDrmLeaseConnector hold a
reference to each other.
In both cases, the reference count was increased. Do not increase the
reference count when lease_connector->lease_device is stored to break
the reference count cycle.

drmModeAddFB() doesn't take a format, but depth and bits per pixel.
These can be used to determine whether there should be an alpha channel
or not, and is roughly assumed to result in either XR24 or AR24 if one
passes 24 or 32 as depth, with 32 as bpp.

In multi-GPU setups, when one of the GPUs is used to render the desktop
and the other one has all of their devices available for lease,
meta_kms_impl_device_list_lessees() can be called after the device fd
has been unhold.
Make sure to hold and unhold it in this function.

When running with COGL_DEBUG=show-uniforms, display the values of the

This function returns a string of the boxed value considering type, size
and count; and adds a name.
e.g:
vec2 scale = vec2(1.0000, 1.0000)
Also handle NULL cases on _cogl_boxed_value_equal.
This will be used by the next commit.

Use _cogl_boxed_value_destroy to free the correspondent array instead of
free, which was only freeing float_array.
Add a new func _cogl_boxed_value_array_alloc to allocate the
corresponding array considering the type.

_cogl_boxed_value_transpose is only used for the matrix type.
Now is named _cogl_boxed_value_copy_transposed_value.
Gets the transposed value considering count (to store in array type or not).
The caller doesn't have to worry about count anymore.
Instead of calling memcpy, add function _cogl_boxed_value_copy_value
which copies the value to the corresponding boxed value property
considering type and count.
The caller doesn't have to worry about type and count anymore.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3965>
There are three array properties, considering type:
1. float *float_array
2. int *int_array
3. void *array
Drop using array. This was inteded to be used when type is matrix and
count > 1, however some functions use it and others use
float_array. Fix this using always float_array, this starts to make all funcs
consistent handling the properties.
There's a mem leak when destroying the boxed value, only freeing the array
prop. Free the corresponding array considering the boxed value type to fix it.
_cogl_boxed_value_set_x func is still inconsistent, the next commits
will solve it.

Colorspace transformation matrices were hardcoded considering only known
colorspaces like bt709 or bt2020.
Now that a colorspace can be defined from its primaries, allow getting the
colorspace transformation matrix from them and drop the hardcoding.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3948>
This is because next commits will generate the colorspace
mapping matrix from the colorspace primaries and won't be required
to define any color space mapping matrix.

The single pixel buffer allows setting colors with 32 bpc.
Attempt to use pixel formats that allow higher precision than BGRA_8888.
First attempt to use half float format, fallback to ABGR_2101010 and
finally fallback to BGRA_8888.

lease_disappeared() was calling meta_drm_lease_disappeared() and
set_connectors_as_available().
meta_drm_lease_disappeared() emits the "revoked" signal, connected to
on_lease_revoked(), which marks the leased connectors as available by
calling set_connectors_as_available().
Therefore, calling set_connectors_as_available() again from
lease_disappeared() is redundant.
Remove the redundant call to set_connectors_as_available() and drop two
unused functions.

Because for `COGL_DRIVER_GL3`, `_cogl_context_get_gl_extensions` needs to
know that the GL version *really* is >= 3.0 before it calls `glGetStringi`
which didn't exist prior to GL 3.0 or ES 3.0.
This was causing crashes on Xilinx Mali implementations that only support
ES 2.0 (hence `glGetStringi` == NULL), but were being forced to call
that function before the GL version check which should tell you the
function isn't supported.
