f97b718b4c waylandsink: Use memfd_create() when available
This (so-far) Linux- and FreeBSD-only API lets users create file
descriptors purely in memory, without any backing file on the filesystem
and the race condition which could ensue when unlink()ing it.

It also allows seals to be placed on the file, ensuring to every other
process that we won’t be allowed to shrink the contents, potentially
causing a SIGBUS when they try reading it.

This patch is best viewed with the -w option of git log -p.

It is an almost exact copy of Wayland commit

deefedd002 waylandsink: Update stale GstBuffer references in wayland buffer cache
"waylandsink: use GstMemory instead of GstBuffer for cache lookup"
changes the cache key to GstMemory, but the cached data still needs
a pointer to the GstBuffer to control the buffer lifecycle.
If the GstMemory used as the cache key moves from one GstBuffer to
another, the pointer in the cached data will be out-of-date.

Update the current GstBuffer pointer for each frame so that it always
represents the currently in use (from attach to release) GstBuffer
for each wl_buffer.

e6944da134 waylandsink: use GstMemory instead of GstBuffer for cache lookup
The GstMemory objects contained in a GstBuffer could be replaced
by an upstream element, which would break the association beteen
the GstBuffer and the wayland wl_buffer, make the cache lookup
results incorrect.
This patch changes the cache lookup to use the first GstMemory
in a buffer instead.  For multi-plane buffers, this assumes that
all of the GstMemory(s) will always be moved together as a set,
and that the same (first) GstMemory isn't used with different
combinations of other GstMemory(s).

ff5f264045 waylandsink: Keep per display wayland buffer caches
Instead of attaching a single wayland wl_buffer to each GStBuffer as qdata,
keep a separate cache for each display.
A unique wl_buffer and associated metadata is created for each display.
This allows for sharing of GstBuffer objects between multiple
displays, such as when using tee elements.

f14206f2b3 waylandsink: Workaround gnome-shell bug
Use a timeout to limit that amount of time we wait after the compositor
for the initial configure event. Compositor are support to emit a
configure event before any wl_buffer can be attached. The problem is
that Weston strongly enforce this, while gnome-shell simply does not
emit such an event.

67bb17e4fa waylandsink: Implement XDG-shell stable support
[wl_shell] is officially [deprecated], so provide support for the
XDG-shell protocol should be provided by all desktop-like compositors.
(In case they don't, we can of course fall back to wl_shell).

Note that the [XML spec] is provided by the `wayland-protocols`
git repository, which is provided by the Wayland project.

2ae381e2a3 waylandsink: Avoid race condition on multi-threaded client
When waylandsink is used on some other thread than the main wayland
client thread, the waylandsink implementation is vulnerable to a

condition related to registry and surface events which handled in
seperated event queue.

The race that may happen is that after a proxy is created, but
before the queue is set, events meant to be emitted via the yet to

set queue may already have been queued on the wrong queue.

Wayland 1.11 introduced new API that allows creating a proxy
wrappper which can help to avoid this race condition.

e2dffab9be waylandsink: consider buffer size when copying to wl shm pool
When the sink receives a buffer that is neither a wl_shm one nor a

being sent to the display.
In that case, the actual size of the received buffer (which may differ
from the one negotiated in the caps) must be used.

57645056ad waylandsink: set video surface opaque
Unless the video format has an alpha component (ARGB, ...), set the
video_surface opaque.
In the usual case where the black area_surface has the same size as the
video_surface (eg: run gst-play-1.0 video.mp4), this makes the black
surface totally occluded which makes weston compositor's life easier
since it can ignore that surface.
Also unconditionally set the black area_surface opaque.
