This fixes all ASan reported leaks in this test.
This test program has several tests named *_multiple that just run
another test function 30 times. Previously without cleanup all the
created clients would be left lingering, but now they are torn down. Ths
might cause a change in test behaviour, although that was never the
intention:
> It is intentional to run it so many times, but it is not intentional
> to run a hundred clients at a time. The problem is that currently we
> have no destroy function for client. However, the clients do not run
> simultaneously but serially, so the effect should be the same as if
> we'd destroy them (after the client finishes its body, it just 'is'
> and does nothing until the process exits)
- the original review discussion in
https://lists.freedesktop.org/archives/wayland-devel/2015-March/020957.html
The intention for the repeat testing is that as the Weston instance
remains from test to another, each test needs to undo its changes to the
devices. Failing to correcntly undo would accumulate devices.

Not printing these will drop 7980 lines or roughly 350 kB from the test
logs. Now I don't have scroll through them all, and I don't have to
watch them if I run this test manually.
These prints were useful when developing the test, but we don't need
them printed in CI all the time. Printing the final count should be
enough.

Now that GL-renderer and color manager implement linear light blending
for sRGB EOTF, add a test case to verify the result is expected.
As noted in test comments, this new tests is quite powerful in ensuring
the whole linear light pipeline is working correctly with 1D LUTs in
GL-renderer. This test will even catch smashing source_lut.scale = 1.0f
and source_lut.offset = 0.0f which would result in wrong texture sample
positions for LUT data.
As the assumption is that by default content and outputs are in sRGB
color space, this test should not need fix-ups or become stale when more
color management features are implemented.
The sRGB EOTF can be found in:
http://www.color.org/sRGB.pdf (beware, typos)
https://www.w3.org/Graphics/Color/srgbhttps://www.khronos.org/registry/DataFormat/specs/1.3/dataformat.1.3.html#TRANSFER_SRGB
Note on AMD Polaris 11 error threshold: this is quite likely due to
using fp16 format shadow framebuffer and GCN fp32 to fp16 conversion
instruction rounding mode. When using fp32 shadow framebuffer, the error
glitch is not present and the threshold could be significantly lower.

Instead of checking just the monotonicity of the blending results, this
changes the alpha-blending test to compute the reference blend result
itself and then comparing to the compositor result. This way we can be
sure that the compositor implements the exact correct formula and not
something that just looks nice, as verifying the reference images are
actually correct is hard.
The reference image is renamed to follow the fact that this is not
primarily a monotonicity test anymore. The reference image is also
redundant, but I think it has documentary value.
The #if 0'd block of code was very useful in figuring out blending
errors in a future test case, so it is included here. I have a feeling
we are going to need it again.

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
would have crashed.

In "backend-drm: simplify compile time array copy", ARRAY_COPY was
introduced to be used by the DRM-backend.
In this patch we expand its usage to other code where hardcoded arrays
are being copied.

In commit "libweston: add struct weston_drm_format" we've added an API
to store and manage DRM formats and modifiers. As it has a couple of set
operations that are not so obvious, this adds unit tests to ensure
correctness. In the future we may expand this API and also improve
performance, so it is important to have this.

This will be useful in CI, where we do not want to see any skips. If
something starts to skip, that's a mistake somewhere, and want to catch
it.

Code is using the form
#if ENABLE_JUNIT_XML
which is fine until we start using -Wundef. I think the existing code
would fail or at least warn if you disabled test-junit-xml with -Wundef.
Make sure ENABLE_JUNIT_XML is always defined so that -Wundef can be
added to build flags.

If the compositor does not have the shadow buffer capability (implied by
the color ops capability bit), then trying to run the shadow buffer test
is useless, it would just fail. Let it skip instead.

This allows tests to skip when required capabilities are not present.
The output damage test for the shadow buffer case needs this.
required_capabilities is added to struct weston_testsuite_quirks which
is libweston public API just because there is no better place currently.
This is a little weird because the code to check it is in compositor,
not libweston.

This will hit the XYUV shader variant in GL-renderer that was not
covered in the test suite before.

This header is for sharing fallback definitions for drm_fourcc.h. A new
test in tests/yuv-buffer-test.c is going to be needing XYUV8888 format,
and more new formats will be expected with HDR supports.
Share these fallback definitions in one place instead of copying them
all over.
All users of drm_fourcc.h are converted to include weston-drm-fourcc.h
instead for consistency: have the same definitions available everywhere.

Extend the existing output-damage test to test
blit_shadow_to_output() specifically. This function had problems
originally, so make sure they can't reappear.
The added quirk is explained in the test.
An additional check of the quirk in gl_renderer_output_create() ensures
that the shadow framebuffer is really used. The test could false-pass if
the shadow is not used.

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.
