Push weston_coord into the notification functions instead of passing
two doubles.
The touch handlers are passed a pointer to a weston_coord, which is
unusual. This is done so we can pass a NULL pointer instead of a
fabricated invalid coordinate when the touch type is TOUCH_UP.

Wayland protocol can't do this, but the way our test protocol handles
touch through a single event can - ensure that we don't by accident.
This will matter more shortly when we add assert()s to prevent having
coordinates with WL_TOUCH_UP events internally later.

While the --backend parameter looks like it takes a file name, it really
is selected from a list of supported strings that are then funneled
through a translation to enum weston_compositor_backend [1].
Because all backend parameters are of the form "...-backend.so", and
writing "--backend=...-backend.so" is boring, allow the --backend option
to match the backend name without "-backend.so" suffix instead.
For example, this allows to use "--backend=headless" instead of
"--backend=headless-backend.so".
Update help text and documentation. Keep the old way working for
backwards compatibility.

When we build up a matrix from a series of operations, it's very useful
to know if the combined operations still result in something that matches
a wl_output_transform.
This adds a function to test if a matrix leads to a standard output
transform, and returns the transform if it does.
Tests are provided that check if complex series of operations return
expected results - the weston_matrix_needs_filtering function is tested
at the same time.

Setting up the arguments may consume some of the arguments, e.g. if we
provide a config file or extra modules, then the test harness is
expected to be responsible for freeing those arguments.
Checking the requirements and bailing first means that we never do that,
and thus skipped tests result in leaks. Flip the order so we set up the
args first and skip last, so we can consistently take ownership of all
the provided setup parameters.

ZUC's default mode is to fork for every test case. Unfortunately on
AArch64, fork in an ASan-traced program usually takes around 3.6 entire
seconds. This was leading to the config-parser test timing out.

support for it.

This commit is truly horrible.
We want to run ASan with leak checking enabled in CI so we can catch
memory leaks before they're introduced. This works well with Pixman, and
with NIR-only drivers like iris or Panfrost.
But when we run under llvmpipe - which we do under CI - we start failing
because:
- Mesa pulls in llvmpipe via dlopen
- llvmpipe pulls in LLVM itself via DT_NEEDED
- initialising LLVM's global type/etc systems performs thread-local
allocations
- llvmpipe can't free those allocations since the application might
also be using LLVM
- Weston stops using GL and destroys all GL objects, leading to Mesa
unloading llvmpipe like it should
- with everything disappearing from the process's vmap, ASan can no
longer keep track of still-reachable pointers
- tests fail because LLVM is 'leaking'
Usually, an alternative is to LD_PRELOAD a shim which overrides
dlclose() to be a no-op. This is not usable here, because when
$LD_PRELOAD is not empty and ASan is not first in it, ASan immediately
errors out. Prepending ASan doesn't work, because we run our tests
through Meson (which also invokes Ninja), leading to LSan exploding
over CPython and Ninja, which is not what we're interested in.
It would be possible to inject _both_ ASan and a dlclose-does-nothing
shim DSO into the LD_PRELOAD environment for every test, but that seems
even worse, especially as Meson strongly discourages globbing for random
files in the root.
So, here we are, doing what we can: finding where swrast_dri.so (aka
llvmpipe) lives, stashing that in an environment variable, and
deliberately leaking a dlopen handle which we never close to ensure that
neither llvmpipe nor LLVM leave our process's address space before we
exit.

This is adding basically a copy of alpha-blending-test.c. The difference
is that here we use ICC files to set up the output color profile, and
then test light-linear blending only. BLOCK_WIDTH is set to 1 to fit
inside the output size used by the fixture setup, which is smaller than
in the original, but does not change the results.
The test is aimed at testing how color-lcms module succeeds in
linearizing the output of different ICC output profiles. Incorrect
linearization should cause changes in blending results.
The tolerance is taken from the currently achieved error statistics
(1.40908) and rounded up a little to achieve a suitable margin.

Switch from per-channel max error tolerance to max two-norm (Euclidean
distance) error. Geometrically this means that previously the accepted
volume was a +/- tolerance cube around the reference point, and now it
is a sphere with tolerance radius.
The real benefit is simplifying the code.
The error tolerance are also changed to float. Integers cannot represent
values between 1 and 2, and the jump from 1 to 2 would have been too
much. AdobeRGB tolerance gets relaxed a bit, while BT2020 tolerance
becomes stricter. The new tolerance values are the reported achieved
two-norm max errors plus a bit of margin.
Surprisingly the sRGB case tolerances remain strictly at zero, and
that's no bug in the test.

The recently introduced rgb_diff_stat value dumping feature logs the
"position" where the value or error was measured. The reference value
was used as the position, but the problem with the reference value is
that it is an output value and not an input value. Therefore mapping
that back to which input values promoted the error is not easy.
Fix that problem by passing the position explicitly into
rgb_diff_stat_update(), just like it is already passed in to
scalar_stat_update().
Currently the only user simply passes the reference value as position,
because there the input value is also the reference value. This is not
true for future uses of rgb_diff_stat.
