e1c4133836 libweston,shared/meson:build Add xkbcommon missing depends
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.

This fixes the following build issue:

6a06669b58 clients: Add support for tablet cursor motion to window frames in libtoytoolkit
When it comes to a window frame, a tablet tool and cursor act almost
identical; they click things, drag things, etc. The tool type and extra
axes don't serve any use in the context of a window frame, so tablet
pointers share the frame_pointer structures used for the mouse pointer.

e1b4ad7d0b matrix: Introduce weston_coord
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.

e13c99690b libweston: Optimise matrix multiplication
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.

92a9860e1d libweston: Add function to find the output transform of a matrix
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

This test is done in a lazy fashion by examining elements of the matrix

9229a45116 shared: rewrite fail_on_null() as abort_oom_if_null()
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.

cbbf0e59a5 ivi-shell: replace MEM_ALLOC() with mostly xcalloc()
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().

6cb2526b67 Move shell-utils to its own directory
shell-utils contains a number of helpers which are currently in use by
both desktop-shell and kiosk-shell. In order to extend this use to
fullscreen-shell as well (which can benefit from reusing the
weston_curtain infrastructure to be able to create solid-colour views
which may or may not be opaque, as well as one function within
fullscreen-shell which was copied wholesale to shell-utils), we need to
create a separate Meson dependency object, and avoid the existing
pattern of including the source from shared/ within the source list for
each shell.

This requires creating a new top-level directory for these shared helper
functions which are required by each shell, but are not part of
libweston in and of itself.

shell-utils depends on libweston-desktop; libweston-desktop depends on
libweston; libweston depends on shared.

Thus it is not possible to expose a dependency object from the shared/
directory which declares a dependency on the libweston-desktop
dependency, as Meson processes directories in order and resolves
variable references as they are parsed.

In order to break this deadlock, this commit creates a new top-level
directory called 'shell-utils' containing only this file, which can be
parsed by Meson after libweston-desktop (making the libweston-desktop
Meson dependency variable available to the build file to declare a
dependency on that), but before the shells (making the new Meson
depenendency object available to each shell which wishes to use it).

This commit contains no functional changes to any observable code.

dc0f73bcac shell: Encapsulate weston_curtain in its own struct
This will allow us to create a solid weston_buffer as well, since we
need to store that separately.

bd9b0676dd shell: Make input capture optional for curtains
desktop-shell's focus surfaces want to reuse this, but they don't want
to capture the input, instead allowing it to fall through.

e81b8d7cc9 shell: Add alpha to weston_curtain_create
Not all solid-colour views want to be opaque: sometimes we use them with
non-opaque alpha values in order to shade views underneath them.
