Given that we have a struct for argument params, we might as well use it

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.

Tablet shell was removed in 873b515aee in

We also gained kiosk shell in the mean time, so mention that instead.
Yes, it's a bit of a lie, because we also have ivi-shell and

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.

When using the libseat launcher, there is one more detail to take care:
stop libseat from managing the VT.
A normal user does not have permissions to manage a VT, so launching
would just fail. In this use case you also do not want to be managing
the VT, because your normal desktop is already owning the seat
associated with the VT.

Give a little more details about how running Weston via ssh or serial
terminal is best done, now that launcher-direct and weston-launch are
gone.
Hopefully the removal of launcher-direct also makes less people run
Weston as root, when seatd is the privileged process. Running 'weston'
as root might still work through libseat's builtin backend without
seatd.

Now that launcher-direct and weston-launch are gone, libseat takes their
place.
Enable libseat support by default to give users a hint in case they miss
either of those.
People who used to get launcher-logind when libseat support was disabled
will now be using logind through libseat. This should not cause any
regressions, and if it does, we want to hear about them, because the
separate logind-launcher is also planned to be deprecated in the future.
Disabling logind-launcher by default is left for when it actually gets
deprecated.
In case someone does not have libseat available but do have logind
running, they can just disable libseat support.

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.

This is a new function exporting macro that intends to make writing unit
tests in the Weston test suite easier.
A test needs to access a private function to be able to verify its
behavior. Previously we have used things like putting such functions in
a separate .c file and then building that file into the corresponding
test. That is a bit awkward and can lead to proliferation of arbitrary
.c files for no good reason. It may also require pre-processor magic,
and sometimes copying chunks of code causing a risk of deviating the
code being tested from the code actually used.
This patch proposes another approach: a private export from a DSO.
Except, private exports do not really exist, and this is just a normal
export with a specific C macro, and omitting the function from public
headers.
Once exported, a test program can link the DSO during build, be that a
shared library or even a plugin, use the private header declaring the
function, and simply call the function in the test.
The declaration of WESTON_EXPORT_FOR_TESTS is in shared/helpers.h so
that it is available to all components equally while still not being in
a public header. Other places that were considered:
- include/libweston/libweston.h is a public header, but external users
should not know about the macro.
- libweston/libweston-private.h is too private and not available to all
components, particularly color-lcms plugin.
- libweston/backend.h is not appropriate for color-lcms plugin either.

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.

Individual struct fields are inconvenient to index into, yet most
operations on a color just repeat the same for each of RGB channel.
Being able to index into RGB avoids repeating the same code for each
channel.
Alpha channel is left as separate, since it is almost never handled the
same as RGB.
The union keeps the old .r, .g and .b addressing working. The static
asserts ensure the aliasing is correct.
For demonstration, two simple functions in color_util.c are converted.
Unfortunately initializers need to be corrected everywhere. Field .a is
not explicitly initialized because it is unused in these cases.
This change should make code easier to read.
This change requires gnu99 or c11 standard. gnu99 is already the default
in top-level meson.build.

1. Use fixture_setup to set the generated by LCMS output profile based on
given chromaticities and white points. The following list of well known
chromaticities:
- sRGB
- adobe RGB
- bt2020
and white point is D65. Use INTENT_ABSOLUTE_COLORIMETRIC to avoid BPC.
Input profile is always sRGB and it is used internally by Weston as
stock profile.
2. Use these hardcoded matrixes as part of pipeline 1DLUT->3x3->1DLUT.
The diagnostic code to retrieve the transform matrix is availble into
test in the comments. The conversion matrixes generated for the
following cases:
- sRGB to sRGB (unity)
- sRGB to adobeRGB
- sRGB to BT2020
3. Compare GPU shaders(gl texture3D) vs manual pipeline calculation
Use different max tolerable error per transform.
There are comments how number of points in 3DLUT is related to tolerance.
Tolerance depends more on the 1D LUT used for the inv EOTF than
the tested 3D LUT size: 9x9x9, 17x17x17, 33x33x33, 127x127x127.
4. Enable build matrix-shaper test if color-management-lcms is enabled.

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.
