In 913d7c15f7 stricter error checking was
introduced to the strtol call, which broke reading backlight values.
Since every sysfs backlight file ends with a newline.
As noted in a comment in the previous MR to prevent damaged pointers
after calling asprintf, replace every asprintf call with str_printf.

The repaint_data is entirely backend specific. Moreover, it is only used by the
drm backend, while other backends ignore the repaint data.
There will always be only one repaint active, thus, there is no need to pass the
repaint data from the outside.
The repaint_data breaks with the multi-backend series, which calls repaint begin
for all backends to get the repaint_data. The repaint_data of the last backend
will then be passed to all other backend. At the moment, this works, because the
drm backend is the only backend that implements the begin_repaint call.
Another option would be to track the repaint data per backend in the compositor,
but actually, it the backend needs to track state across the calls, it's its own
responsibility.

The pending_state is already stored in the backend and can be directly retrieved
from there.
This avoids involving the compositor in passing state between the repaint
phases for a single backend.

Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.
Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.
I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.
Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

The built-in backend of libseat requires users to enable a logging
level in order for libseat to start writing out log messages. For that
to happen we split out the info and error log level messages into the
compositor's log scope, while debug level messages go into a dedicated
scope.
With that, this patch brings in a new scope, called libseat-debug, which
users need to explicity create a subscription for it as to retrieve/have
access to debug message coming out of libseat. Note that by default we
have a subscription for the log-scope so any errors/info from libseat
would be displayed to the user.

This is probably the simplest case to demonstrate how to use
WESTON_EXPORT_FOR_TESTS.
Previously, vertex-clip test re-built vertex-clipping.c for itself. Now
it directly links in gl-renderer.so instead as that is where
vexter-clipping.c gets built into for actual use. This probably will not
work for any installed program, but luckily tests are never installed,
so Meson makes sure the DSO is found.
Unfortunately we cannot remove the definition of dep_vertex_clipping
yet, because clients/cliptest.c needs it.
This makes vertex-clip test depend on GL-renderer, but that is where the
code is really used.

Although weston_compositor_run_key_binding() is called when the current
keyboard grab is default_grab or input_method_grab, swallowing the key
event is processed only on default_grab. As a result key events that
should be swallowed are sent to the input method unexpectedly.
For example, when a user press `Super + s` on weston-editor to take a
screen shot, `s` will be unexpectedly entered to the text area.
I confirmed such behaviour with weston-simple-im and fcitx5-5.0.10.
It doesn't occur with weston-keyboard because it doesn't install
keyboard grab.

Thanks to Pekka for great simplifications in implementation, like the xyz_dot_prod()
Quote: "should help untangle lots of the multiplications and summations by saying
we are computing dot products, etc".
The approach was validated using matrix-shaper and cLUT type of profiles.
If profile is matrix-shaper type then an optimization is applied.
The extracted EOTF is inverted and concatenated with VCGT, if it is availible.
Introduce function cmlcms_reasonable_1D_points which would be shared between
linearization method and number of points in 1DLUT for the transform.

1. The cmlcms_category is used to identify the purpose of transform:
- CMLCMS_CATEGORY_INPUT_TO_BLEND
- CMLCMS_CATEGORY_BLEND_TO_OUTPUT
- CMLCMS_CATEGORY_INPUT_TO_OUTPUT
2. Added following fields to cmlcms_color_profile:
- output_eotf - If the profile does support being an output profile and it
is used as an output then this field represents a light linearizing
transfer function and it can not be null. The field is null only if
the profile is not usable as an output profile. The field is set when
cmlcms_color_profile is created.
- vcgt - VCGT tag cached from output profile, it could be null if not exist
- output_inv_eotf_vcgt - if the profile does support being an output profile and it
is used as an output then this field represents a concatenation of inverse
EOTF + VCGT, if the tag exists and it can not be null.
3. Added field cmsHTRANSFORM to cmlcms_color_transform.

The following GL extensions provide support for shaders CM:
-GL_OES_texture_float_linear makes GL_RGB32F linear filterable.
-GL ES 3.0 provides Texture3D support in GL API.
-GL_OES_texture_3D provides sampler3D support in ESSL 1.00.
If abovesaid is supported then renderer sets flag WESTON_CAP_COLOR_OPS
which means that all fields in struct weston_color_transform are
supported, for example, 1DLUT and 3DLUT.
Use GL_OES_texture_3D to implement 3DLUT function which
uses trilinear interpolation for pixel processing or bypass as is.

We can end in `subsurface_committed()` in different scenarios
without the surface having an attached buffer. While setting
the mapped state to `true` in that case doesn't matter for
that (sub)surface itself, it triggers its own child subsurfaces
to get mapped when they shouldn't.

Zoom is a neat trick, but in its current form it's very hard to test
and maintain.
It also causes output damage to scale outside of the output's boundaries,
which leads to an extra clipping step that's only necessary when zoom
is enabled.

For subsurfaces in sync mode, arguably the same is the case until the
cached state gets applied eventually. Thus, in order to keep complexity
to a sane level, just accumulate buffer damage and convert it only
when the cached state gets applied.
This mirrors how other compositors like Mutter implement cached damage
and what the spec arguably should demand.

These formats are useful because they are often easier to produce
on CPU than half-float formats, and abgr16161616 has both >= 10bpc
color channels and adequate alpha, unlike abgr2101010.
The 16-bpc textures created from buffers with these formats require
the GL_EXT_texture_norm16 extension.
As WL_SHM_FORMAT_ABGR16161616 was introduced in libwayland 1.20,
update Weston's build requirements and CI.
The formats also needed to be registered in the pixel format table,
and defined in a fallback path if recent libdrm is not available.

We just copy the SHM buffer straight into a separately-allocated GBM BO,
so no need to take a reference on the buffer itself or keep it from
being released.
All drm_output_try_view_on_plane really does at this point is to call
the prepare_*_view function for the requisite plane type, and take a ref
on the weston_buffer from the client. Given that we don't need to keep
the client buffer alive, we can short-circuit
drm_output_try_view_on_plane, and instead just call
drm_output_prepare_cursor_view directly when we have a cursor plane.
This also makes it easier to just remove drm_output_try_view_on_plane in
following patches when we merge the overlay/scanout plane path into one.
Doing so gives us two clearly-separated paths: one for copying a SHM
client buffer into a cursor, and another for directly scanning out
client content.

For views which cover the entire output, we always attempt to place them
on the primary plane, to avoid a situation where we place a fullscreen
view into an overlay plane and then have to disable the primary plane,
which doesn't always work.
Move this check earlier, so we don't consider overlay planes to be
candidates for fullscreen views. This check should be changed in future
to only filter for opaque views, but that's for another time.
