Effective from Linux 6.3 onward, this creates the memfd without execute
permissions and prevents that setting from ever being changed. A
run-time fallback is made to not using MFD_NOEXEC_SEAL when
weston compiled on Linux >= 6.3 is run on Linux < 6.3.

Currently in translate_curve_element() we always translate the curve
into a LUT. But in the future we'll be able to translate the curves to
parametric ones.
So move the current code to a new function
translate_curve_element_LUT(), so that in translate_curve_element() we
are able to call one of the two functions (_LUT() or _parametric()).
No behavior changes, just preparation for the upcoming patches.

Not a behavior change, but this allow us to decide what function pointer
to use within this function (instead of forcing callers to decide that).
In the following commits this will be helpful. We'll add more curves
besides 3x1D LUT's and, depending on the curve, the function pointer
signature may differ.
Also, we now pass the xform directly to the function, and it can select
the curves depending if it is being called for a pre or a post curve.

When we are destroying the color manager, the components referencing
color profiles should have already been destroyed. We have an assert
in cmnoop_destroy() to make sure that the stock profile has refcount
equal to 1.
But we currently have an issue in Weston. While shutting down with
client surfaces alive, we may leak them. So we try to destroy
the color manager with surfaces still alive, and they may be
referencing color profiles.
We already have a workaround for this in our LittleCMS color plugin,
but we've missed that in color-noop. This fixes that, so now we don't
hit the assert anymore.
As we are already dealing with asserts in color-noop, I took the
liberty to replace the last usage of assert with our own wrapper
in this file.

In this MR we add support to the majority of the interfaces from the
color-management protocol.
That means that we are able to advertise output's images descriptions to
clients, preferred surface images descriptions, and so on. We also
support clients that wants to create ICC-based images descriptions and
set such descriptions for surfaces.
We still don't support the interface to allow clients to create
image descriptions from parameters, but that should be addressed
in the near future.

Add yet another flavor of assertion macros.
Unlike libc assert.h assert(), these cannot be easily disabled by the
build. They also print both the implied expression and the compared
values.
Unlike ZUC macros, there is much less framework code and it can handle
also floating-point types.
The function custom_assert_fail_ can be redefined, meaning that
different compilation units can do different things on failure.
Also the 'compositor' parameter was added to the new macros because we
plan to use these asserts in our log infrastructure, and we want to
print the "failure" messages in the right log scopes. Having the
compositor already in the macros will avoid double work.
Another future possibility is to write specific asserts for the test
suite. So we would be able to write a test suite failure function that
just print what "failed" without aborting.
There is also limited support for custom types.
These are actually pretty similar to libinput's litest macros.

This is because e619a65b09, 'libweston: move gl-borders code into
helper lib' and 6293ab1f90, 'libweston, shared: Move out
weston_shell_get_binding_modifier' moved things out of libweston, and
libweston implicitly depends on xkbcommon.
Rather than just depending on dep_xkbcommon use the deps_for_libweston_users
which includes some other dependencies as well. Had to move it out
of libweston/meson.build and include it in the main meson.build as
libweston/meson.build would have a circular dependency on
libweston/meson.build file.

All through weston we have code that passes int x, y or
float x, y or wl_fixed_t x, y pairs. These pairs are frequently
converted to/from wl_fixed_t and other types.
We also have struct vec2d and struct weston_geometry which also
contain coordinate pairs.
Let's create a family of coordinate vector structures for coordinate
pairs and use it anywhere we sensibly can.
This has a few benefits - it helps remove intermediate conversion
between fixed/float/int types. It lets us roll the homogenous
coordinate normalization bits into helper functions instead of
needing them open coded throughout the source.
Possibly most importantly, it also allows us to do some compile time
validation of what coordinate space we're working in.

The previous version used div() to separate the column and row of the
current element, but that function is implemented as a libc call, which
prevented the compiler from vectorising the loop and made matrix
multiplication appear quite high in profiles.
With div() removed, we are down from 64 calls to vfmadd132ss acting on
one float at a time, to just 8 calls to vfmadd132ps when compiled with
AVX2 support (or 16 mulps, 16 addps with SSE2 support only), and the
function isn’t a hot spot any more.

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.

If a transformation matrix causes a scale, a rotation not a multiple of 90
degrees or a non-integral translation then textures rendered with
it would benefit from bilinear filtering.

Recently I learnt that fprintf() is not async-signal-safe. Maybe it also
attempts to allocate memory sometimes. Hence, using it when we
presumably are out of memory is wishful thinking.
Therefore replace that with async-signal-safe code. If you have to check
pointers from traditional signal handlers, now you could do that too!
While doing this, we also lose the string formatting for line number. I
would argue that printing file and line number is not that useful, if
the system really is out of memory. If not out of memory, a core dump
would give us much more detailed information about what went wrong.
clients/window.c had some calls to fail_on_null() and these are simply
replaced. They were used for checking that creating new wl_proxy by
issuing a protocol request worked, and IIRC that only fails on
out-of-memory, so the same rationale applies here.

Drop the even more home-grown alloc wrapper and use the xalloc.h
wrappers directly.
xcalloc() is added and used, because calloc() will detect integer
overflows in the size multiplication, while doing a simple
multiplication in the caller is subject to overflows which may result in
allocating not what was expected, subjecting to out-of-bounds access.
All MEM_ALLOC() calls that had a meaningful multiplication in them were
converted to xcalloc(), the rest to xzalloc().
