Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
This creates the FP16 shadow framebuffer automatically if the color
transformation from blending space to output space is not identity and
the backend does not claim to implement it on the renderer's behalf.
That makes the weston_output_set_renderer_shadow_buffer() API and
use-renderer-shadow weston.ini option obsolete.
To still cater for the one test that needs to enable the shadow
framebuffer in spite of not needing it for color correct blending, the
quirk it uses now also forces the shadow.

expect_protocol_error() ensures that the connection has failed in the
expected way. To satisfy ASan leak detection, we still need to tear down
everything, including call client_destroy().
client_destroy() needs to check that tear-down does not cause protocol
errors, so it does one last roundtrip that checks that is succeeds. But
if the connection is already down in an expected way, this roundtrip
cannot succeed and must be skipped.
Also moves the roundtrip under 'if (wl_display)', assuming the 'if' is
there for a reason - but obviously that reason was never used as it

Proper color management will need blending done with linear light pixel
values, that is, EOTF applied before blending, and then inverse-EOTF
applied for scanout after blending. The simplest way to set that up is
to use an intemediate framebuffer a.k.a shadow buffer containing the
composited image in linear light values, then blit from that to the
actual framebuffer.
This patch implements the shadow buffer, but the linear light
blending is left for another patch. This allows GL-renderer to turn
WESTON_CAP_COLOR_OPS on.
Half-float is chosen as the buffer format because linear light values
require more bits to encode with sufficient precision than the usual
non-linear pixel values.

This adds a test to ensure that the wl_shm formats YUV420, NV12 and YUYV
are decoded and converted to RGB correctly in GL-renderer.
The test deliberately uses a 256 x 256 test image so that effects from
width vs. pitch vs. stride cannot be observed, and row padding is zero.
Also padding between planes is zero. Attempting to use a test image with
less "round" dimensions lead to stride mismatch in GL-renderer, likely
due to GL_UNPACK_ALIGNMENT being left at value 4. It is unclear if YUV
wl_shm buffers' row stride needs to be aligned to 4 bytes or not, so I
did not pursue fixing it. GL-renderer seems to be confusing width, pitch
and stride even further, and not e.g. allow padding with ARGB buffers.
See also: https://gitlab.freedesktop.org/wayland/weston/-/issues/354
Furthermore, the test arranges so that each 2x2 pixel block has the same
color. This avoids having to consider chroma siting when sub-sampling.
This way all the test cases can use the same reference image.

There are some specific cases in which we need Weston to
behave differently when running in the test suite. This
adds a new API to allow the tests to select these behaviors.
For instance, in the DRM backend we plan to add a writeback
connector screenshooter. In case it fails for some
reason, it should fallback to the renderer screenshooter
that all other backends use. But if we add a test to
ensure the correctness of the writeback screenshooter,
we don't want it to fallback to the renderer one, we
want it to fail. With this new API we can choose to
disable the fallback behavior specifically for this test.

Currently doesn't exist a standard way to write a weston.ini inside a test.
Here, two new functions `weston_ini_setup` and `cfgln` are introduced to
help the test writer to write a weston.ini file and load it to the test.
And `internal-screenshot-test` is converted to use the new method of write
a weston.ini. This conversion serves as example and initial API test.
The tester needs to call `weston_test_harness_execute_as_client` or
`weston_test_harness_execute_as_plugin` in the same way as before.
The `weston_ini_setup` will fill the setup->config_file with the
correct path to the weston.ini file.
The main design goal is to avoid pre-made or build-made weston.ini(s)
and keep the test as self-contained as possible.

With this patch we add support to run DRM-backend tests locally

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).
