These shell utils functions are potentially useful to other shells as
well, so make them widely available.
Renamed all functions to weston_shell_utils namespace.

Reorder the sections into what people care about: what is it, how do I
build it, how do I run it, where are the docs for when I want to do
more?
The libweston section has been substantially rewritten to trim the
details down to what is accurate and relevant, and the introduction has
accordingly been updated to reflect the reality of Weston as a project
today.

When the pointer is confined and we are handling motion, we need
up-to-date view transforms in order to respect the confinement. So
update view transforms in such case.
This fixes an issue in which we'd try to transform views with dirty
transforms in weston_pointer_clamp_event_to_region(), hitting an assert.
This is a leftover of d611ab24 "libweston: Update view transforms more
often".

When the output is moved, move its per-framebuffer accumulated damage
with it. The alternative would be to track accumulated damage in the
local output coordinate system, but that would require translating back
into global coordinates for repaint_output.

Use the gl-renderer border code shared with headless-backend. We can
drop all this open-coded stuff.
In the output disable path, make sure to call this only when gl-renderer
is used. It will also reset the border state in gl-renderer, which is
harmless here, and it's necessary in the resize path.

Move this code from headless-backend to a helper library, so it can be
shared with wayland-backend.
gl-renderer.h was missing #pragma once, which made the build fail.
Unfortunately gl-borders needs gl-renderer.h which will attempt to
include EGL headers if gl-renderer is enabled in the build, so we must
get the EGL build flags too, just for the headers.

GL-renderer keeps the pointer for the border image data for later use.
When we destroy our cairo_surface, that data gets freed. Therefore,
reset the pointer stored by GL-renderer too, to ensure use-after-free
cannot happen.
This is not really necessary in this particular case, because the
renderer output is destroyed immediately after, so there is no chance of
UAF.
However, this is needed for code sharing purposes. Wayland-backend will
do exactly this when an output is resized. To share this code with
wayland-backend, we also need to reset the pointers. It's harmless and
more correct in the output disable path.

Make sure dep_egl is always a valid dependency object, even if not
found. Ensure it is not found when not wanted, to avoid linking when
found but not wanted.
Using a not-found dependency in Meson is defined to be a safe no-op, so
use that to simplify the backend dependencies.
libweston/meson.build already errors out if renderer-gl is enabled and
EGL is not found, so the same checks can be removed from the backends.

Now that struct weston_head contains a pointer to the backend owning

Compositor code can use opaque pointer comparison to determine whether
a head belongs to a given backend. Store a backend pointer in struct
weston_head to enable the compositor to select the correct backend
specific output configuration code.
This also allows to use the backend pointer instead of the opaque
backend_id pointer to check whether a head belongs to a backend, so
replace the checks in all to_xyz_head() functions and drop backend_id.

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.
