Check and ensure that a compositor can only load one backend
successfully. If a backend fails to load, it is theoretically possible
to try another backend. Once loading succeeds, only destroying the
compositor would allow "unloading" a backend.
If backend init fail, ensure the backend pointer remains NULL to avoid
calling into a half-loaded backend on e.g. compositor destruction.

'release' is a more appropriate name because the function does not free
the underlying memory. The main reason for this is that we need the name
weston_output_destroy() for new API that actually will free also the
underlying memory.
Since the function is only used in backends and external backends are
not a thing, this does not cause libweston major version bump, even
though it does change the ABI. There is no way external users could have
successfully used this function.

This fixes a regression where monitor make and model would always be
advertised as "unknown" to Wayland clients. The EDID strings were parsed
at create_output_for_connector() time, but the fallback "unknown" values
were set in weston_drm_output_api::set_mode vfunc later. This made the
correct monitor info be shown in the log, but not sent to clients.
The purpose of the "unknown" assignments is to give fallback values in
case EDID is not providing them.
Fix all that by moving all setting of the make, model and serial into
create_output_for_connector(). These values cannot change afterwards
anyway. While at it, document find_and_parse_output_edid().
The ugly casts in create_output_for_connector() are required to silence
compositor warnings from ignoring const attribute. This is temporary,
and a future refactoring will get rid of the casts.

Add 'name' argument to weston_output_init(). This is much more obvious
than the assert inside weston_output_init() to ensure the caller has set
a field in weston_output first.
Now weston_output_init() will strdup() the name itself, which means we
can drop a whole bunch of strdup()s in the backends. This matches
weston_output_destroy() which was already calling free() on the name.
All backends are slightly reordered to call weston_output_init() before
accessing any fields of weston_output, except the Wayland backend which
would make it a little awkward to do it in this patch. Mind, that
weston_output_init() still does not reset the struct to zero - it is
presumed the caller has done it, since weston_output is embedded in the
backend output structs.

Initialize the list in weston_output_init() instead of doing it
separately in each backend.
One would expect weston_output_init() to initialize all weston_output
members, at least those that are not NULL.
We rely on the set_size() functions to be called only once, as is
assert()'d. If set_size() becomes callable multiple times, this patch
will force them to be fixed to properly manage the mode list instead of
losing all members.
compositor-wayland.c is strange in
wayland_output_create_for_parent_output(): it first called
wayland_output_set_size() that initialized the mode list with a single
mode manufactured from width and height and set that mode as current.
Then it continued to reset the mode list and adding the list of modes
from the parent output, leaving the current mode left to point to a mode
struct that is no longer in the mode list and with a broken 'link'
element. This patch changes things such that the manufactured mode is
left in the list, and the parent mode list is added. This is probably
not quite right either.

Use EGL fence sync objects to emit timepoints for the beginning and the
end of rendering on the GPU. The timepoints are emitted asynchronously
using the sync file fds associated with the fence sync objects. The sync
file fds are acquired using the facilities provided by the
EGL_ANDROID_native_fence_sync extension.
The asynchronous timepoint submissions are stored in a list in
gl_output_state until they are executed, and any pending submissions
that remain at output destruction time are cleaned up.
If timelining is inactive or the required EGL extensions are not
present, then GPU timepoint processing and emission are skipped.
Note that the GPU timestamps returned by sync files are in the
CLOCK_MONOTONIC clock domain, and are thus compatible with the

However, Weston uses 'primary_plane' internally to refer to the case
where client content is _not_ directly displayed on a plane, but
