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.

8e79e53c6e wlvideoformat: clean up video formats
It cleans up videoFormat by combining the wl_shm_formats and
drm_formats into a single table that represents the same format.
In addition, it adds NV61 format to the waylandsink.

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.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/897

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
dmabuf one, this buffer is copied to an internal wl_shm buffer before
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.

2ad337e440 waylandsink: support linux dmabuf protocol
Support the wayland zwp_linux_dmabuf_unstable_v1 protocol.
SHM formats and DMABuf formats are exposed differently in caps: the
DMABuf formats are flagged with GST_CAPS_FEATURE_MEMORY_DMABUF.
No buffer pool is proposed for DMABuf buffers, it is the upstream
element responsibility to provide with such buffers.

c9aaa4189b waylandsink: Add exception code for setting wl_surface
Waylandsink needs exception code in gst_wayland_sink_set_window_handle().
After making sink->window, User can call
gst_wayland_sink_set_window_handle(). It is the user's fault, but
Waylandsink needs to handle the exception, if not then sink->window is
changed and rendering fails.

c2f34b9814 waylandsink: don't advertise the local wl_display context
This wl_display proxy is temporary only until waylandsink goes NULL,
at which point the connection to the display is disposed. Unfortunately,
if this is advertised as a GstContext, playbin will cache it and re-feed
it to the sink when it goes PLAYING again, but the wl_display pointer
will at that point be invalid and cause a crash.

Another solution to the problem would be to also cache the GstWlDisplay
object inside the GstContext, which would automatically ref-count
the display connection, but I see no reason in doing that at the moment,
as there are no known users of this GstContext outside waylandsink.
It's probably better to avoid chasing hidden refcounts.

23bb5f5319 waylandsink: do not render twice the same buffer
Do not try to render a buffer that is already being rendered.
This happens typically during the initial rendering stage as the first
buffer is rendered twice: first by preroll(), then by render().
This commit avoids this assertion failure:

  'meta->used_by_compositor == FALSE' failed

5b1c5dbf99 waylandsink: stack the video subsurface into another subsurface that covers the whole render rectangle
The main reason behind this is that when the video caps change and the video
subsurface needs to resize and change position, the wl_subsurface.set_position
call needs a commit in its parent in order to take effect. Previously,
the parent was the application's surface, over which there is no control.
Now, the parent is inside the sink, so we can commit it and change size smoothly.

As a side effect, this also allows the sink to draw its black borders on
its own, without the need for the application to do that. And another side
effect is that this can now allow resizing the sink when it is in top-level
mode and have it respect the aspect ratio.

4377a5d71c waylandsink: remove the ugly gst_wl_display_stop() now that this mechanism is not needed anymore
Because we no longer have a custom buffer pool that holds a reference
to the display, there is no way for a cyclic reference to happen like
before, so we no longer need to explicitly call a function from the
display to release the wl_buffers.

However, the general mechanism of registering buffers to the display
and forcibly releasing them when the display is destroyed is still
needed to avoid potential memory leaks. The comment in wlbuffer.c
is updated to reflect the current situation.
