With this patch we add support to run DRM-backend tests locally
in the test suite. For now this won't work in the CI, as there
are no cards available. But the plan is to achieve this by using
VKMS (virtual KMS) in the future.
To run DRM-backend tests locally, first of all the user has to
set the environment variable WESTON_TEST_SUITE_DRM_DEVICE to
'card0', 'card1' or any other device where he wants to run
the tests. Also, for now it only works if it is run as root,
but in the future this problem will be solved.
The tests will run on a non-default seat. The reason for that
is that we want to avoid opening input devices unnecessarily.
Also, since DRM-backend usage requires gaining DRM master status
on a DRM KMS device, nothing else must be using the device at
the same time. To achieve this we use a lock to run the
DRM-backend tests sequentially.

The test suite is dealing only with headless-backend tests.
In order to make it able to run DRM-backend tests, we have
to properly select the renderer that it will use.
This patch add the command line option --use-pixman if the test
defines the DRM-backend renderer as RENDERER_PIXMAN, and it will
add nothing to the command line if it defines RENDERER_GL (the
DRM-backend default renderer is already GL). Also, if the user
defines the DRM-backend renderer as RENDERER_NOOP, the test will
fail (as it should, since DRM-backend does not implement it).

In the test suite we have some default options which
are command line arguments used by most of the tests.
Two of these are width==320 and height==240. But
when we have DRM or fbdev backends, width and height
are not possible command line arguments. This makes
impossible to run tests that uses one of these types
of backends, as the compositor won't open if the
command line string is wrong.
Fix this by not passing command line arguments width
and height if the backend is DRM or fbdev.

With these, a test can initialize the headless-backend with non-default scale
and transform which allows testing output scales and transforms.

This shall be used by CI due to https://gitlab.freedesktop.org/mesa/mesa/issues/2219
It defaults to true, meaning that people by default will be running the
GL-renderer tests. It works fine on hardware drivers, just not llvmpipe.

Instead of relying on Meson setting up environment so that Weston and tests
find all their files, build those values into the tests. This way one can
execute a test program successfully wihtout Meson, simply by running it.
The old environment variables are still honoured if set. This might change in
the future.
Baking the source or build directory paths into the tests should not regress
reproducible builds, because the binaries where test-config.h values are used
will not be installed.

This replaces the old test harness with a new one.
The old harness relied on fork()'ing each test which makes tests independent,
but makes debugging them harder. The new harness runs client code in a thread
instead of a new process. A side-effect of not fork()'ing anymore is that any
failure will stop running a test series short. Fortunately we do not have any
tests that are expected to crash or fail.
The old harness executed 'weston' from Meson, with lots of setup as both
command line options and environment variables. The new harness executes
wet_main() instead: the test program itself calls the compositor main function
to execute the compositor in-process. Command line arguments are configured in
the test program itself, not in meson.build. Environment variables aside, you
are able to run a test by simply executing the test program, even if it is a
plugin test.
The new harness adds a new type of iteration: fixtures. For now, fixtures are
used to set up the compositor for tests that need a compositor. If necessary, a
fixture setup may include a data array of arbitrary type for executing the test
series for each element in the array. This will be most useful for running
screenshooting tests with both Pixman- and GL-renderers.
The new harness outputs TAP formatted results into stdout. Meson is not
switched to consume TAP yet though, because it would require a Meson version
requirement bump and would not have any benefits at this time. OTOH outputting
TAP is trivial and sets up a clear precedent of random test chatter belonging
to stderr.
This commit migrates only few tests to actually make use of the new features:
roles is a basic client test, subsurface-shot is a client test that
demonstrates the fixture array, and plugin-registry is a plugin test. The rest
of the tests will be migrated later.
Once all tests are migrated, we can remove the test-specific setup from
meson.build, leaving only the actual build instructions in there.
The not migrated tests and stand-alone tests suffer only a minor change: they
no longer fork() for each TEST(), otherwise they keep running as before.
