This allows tests to give a meaningful name for their fixture setups
when they use more than one of them.
If a test uses DECLARE_FIXTURE_SETUP_WITH_ARG(), it must now pass a
third argument naming the field which is struct fixture_metadata. This
also means that the fixture setup data must now be a struct, it cannot
be a plain type anymore. A compiler error is generated if the field type
is not the expected one.
All tests using DECLARE_FIXTURE_SETUP_WITH_ARG() and converted to the
new form and given names for their fixture setups.
The fixture setup names not actually used yet, that will be another
patch.

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.

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.

This is a follow-up of commit "tests: start to use Weston's
default screenshooter in the test suite".
As we've started to use Weston's default screenshooter
implementation and protocol extension in the test suite,
we don't need what we've created specifically for the test

Drop test suite screenshooter implementation and protocol
extension.

Until now we had two different protocol extensions: one for the
test suite screenshooter and other for the screenshooter client.
As they are identical and this won't change, make the test suite
use the same protocol that the screenshooter client uses.
Besides the cleanup, this change will also allow us to use the
DRM writeback screenshooter in the test suite, as the test suite
implementation is hardcoded to use a renderer based screenshooter.

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.

Signed-off-by: Igor Matheus Andrade Torrente <igormtorrente@gmail.com>
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
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.

This test ensures that
"pixman-renderer: half-fix bilinear sampling on edges"
keeps on working.
Unlike in the original report
https://gitlab.freedesktop.org/wayland/weston/issues/373, here we use buffer
scale 2 instead of output scale 2 to trigger bilinear filter. The effect is the
same, the actual resulting image in the failing case is just a little
different. This is so that it will be easy to add more viewport screenshooting

- client_create_viewport() does not leak the viewporter object.

This goes through all output transforms with two different buffer transforms
and verifies the visual output against reference images.
This commit introduces a new test input image 'basic-test-card.png'. It is a
small image with deliberately odd and indivisible dimensions to provoke bad
assumptions about image sizes. It contains red, green and blue areas which are
actually text that makes it very obvious if you have e.g. color channels
swapped. It has a white thick circle to highlight aspect ratio issues, and an
orange cross to show a mixed color. The white border is for contrast and a 1px
wide detail. The whole design makes it clear if the image happens to be rotated
or flipped in any way.
The image has one pixel wide transparent border so that bilinear sampling
filter near the edges of the image would produce the same colors with both
Pixman- and GL-renderers which handle the out-of-image samples fundamentally
differently: Pixman assumes (0, 0, 0, 0) samples outside of the image, while
GL-renderer clamps sample coordinates to the edge essentially repeating the
edge pixels.
It would have been "easy" to create a full matrix of
every output scale & transform x every buffer scale & transform, but that
would have resulted in 2 renderers * 8 output transforms * 3 output scales *
8 buffer transforms * 3 buffer scales = 1152 test cases that would have all
ran strictly serially because our test harness has no parallelism inside one
test program. That would have been slow to run, and need a lot more reference
images too.
Instead, I chose to iterate separately through all output scales & transforms
(this patch) and all buffer scales & transforms (next patch). This limits the
number of test cases in this patch to 56, and allows the two test programs to
run in parallel.
I did not even pick all possible scale & transform combinations here, but just
what I think is a representative sub-set to hopefully exercise all the code
paths.

It turns out that if the client is not explicitly destroyed, it will remain
connected until the compositor shuts down because there is no more a client
process that would terminate.
Usually this is not a problem, but if a test file has multiple screenshooting
tests, the windows from earlier tests in the file will remain on screen. That
is not wanted, hence implement client destruction.
To properly destroy a client, we also need a list of outputs. They used to be
simply leaked. This does not fix wl_registry.global_remove for wl_outputs, that
is left for a time when a test will actually need that.
This patch makes only ivi-shell-app test use the new client_destroy() to show
that it actually works. The added log scopes prove it: destroy requests get
sent. Sprinkling client_destroy() around in all other tests is left for a time
when it is actually necessary.
ivi-shell-app is a nicely simple test doing little else, hence I picked it.

The string from get_test_name() can be used for writing screenshot files and
others. Starting the name with the fixture number makes an alphabetized listing

This adds the necessary fuzz to image matching to let GL-renderer pass.
The difference is due to rounding. weston-test-desktop-shell.c uses
weston_surface_set_color(dts->background_surface, 0.16, 0.32, 0.48, 1.);
to set the background color. Pixman-renderer will truncate those to uint8, but
GL-renderer seems to round instead, which causes the +1 in background color
channel values.
0.16 * 255 = 40.8
0.32 * 255 = 81.6

The ivi-layout-test comprises of two halves: the client and the plugin. This
migrates the test to the new test harness.
In the old harness, the plugin was built as the test in meson.build and it fork
& exec'd the client part. In the new harness client tests start from the client
program which sets up the compositor in-process, so now the client is built as
the test in meson.build and the plugin is just an additional file.
Therefore there is not need for the plugin for fork & exec anything anymore, so
all that code is removed.
