This fixes a leak found running drm-smoke-test with ASan. Do not forget
to call prog_args_fini() when:
- skipping DRM-backend tests because we don't have
WESTON_TEST_SUITE_DRM_DEVICE set.
- we fail to acquire the lock needed to run DRM-backend tests.

This simulates an output removal which should trigger a crash when
the compositor is shutdown abruptly by having a view with a listener installed
on its output_destroy signal.
This patch assumes that weston_compositor_remove_output() has already
been amended to use the more safer version for triggering signal
emission.
As both shells use this construct it should catch any potential signal
corruption.

drm-smoke-test can't run at the same time as anything else which touches
DRM devices. This includes any test which would use the GL renderer or
GL/GBM on the client side, since they will open DRM devices to probe
them at init time.

This is prompted by the spurious CI failure
https://gitlab.freedesktop.org/wayland/weston/-/jobs/13891809
saying:
31/36 output-damage TIMEOUT 122.52s 8 subtests passed
32/36 output-transforms TIMEOUT 122.52s 16 subtests passed
33/36 subsurface TIMEOUT 122.52s
34/36 xwayland TIMEOUT 122.51s
35/36 ivi-shell-app TIMEOUT 122.51s
ERROR: Job failed: execution took longer than 5m0s seconds
That is hitting both kinds of timeouts at the same time: the per-test
timeouts, and the CI job total timeout.
That run seems to have had a particularly ill fortune, as a simple retry
finished the same job in 2 minutes, and the longest running test took
only 24 seconds.
Nevertheless, by Daniel Stone's suggestion let's bump both timeouts:
- the per-test timeout to 120 seconds, which with the multiplier in CI
goes up to 8 minutes
- the job timeout for all build related jobs to 15 minutes
The timeout for tests_standalone is not bumped as we are not adding
significant amounts of new tests there.

Since commit "drm-formats: save result of intersection in the first
array", every block of code where weston_drm_format_array_create() and
destroy() are being called could use init() and fini() instead.
Remove these two functions from the API to make it leaner. This patch
also modifies the code that depends on these functions to use init() and
fini().

In the current API, we have some set operations: join, intersect and
subtract. Both join and subtract receives two DRM format arrays and save
the result in the first one.
For the intersection we have a slightly different approach, what makes
the API weird. We don't save the result in the arguments, instead we
return a new array with the result.
Modify weston_drm_format_array_intersect() in order to make it similar
to the other two set operations.

Our core test structure is 36 bytes wide. Declaring it with a 32-bit
alignment should thus stripe it to 64 bytes. For some reason, clang+lld
lays them out with a 96-byte stride within the section (does it want an
entire 32-bit word when building with ASan?), getting the code wildly
confused when it tries to step through the structures.
So we could fix all our tests to avoid the fragile section dance, or we
could just waste another 4 bytes per test definition by bumping the
alignment up to 64 bytes, which seems to do enough to magically accord
with what clang+lld+ASan expect.

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)

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

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

While at it, let's do this properly for once:
- put the creation in a new function
- hook up to the weston_surface destroy signal so this actually gets
freed (fixes the leak)
- check that we don't overwrite another surface role
- check that committed_private actually is ours
- set the surface label func so it gets properly listed in debugs and
traces
- use the proper surface role setup call, so no-one stomps on anyones
toes if a test makes a mistake by using a wrong wl_surface
