e4ed64b731 wayland: free the frame in frame_release_callback()
This basically reverts 62c3888b76 (wayland:
decouple wl_buffer from frame).

Otherwise the frame may be overwritten while it is still used by the
compositer:

The frame done callback (frame_done_callback()) is called, when the
compositor is done processing the frame and hands it to the hardware.
The buffer release callback (frame_release_callback()) is called when the
buffer memory is no longer used.

This can be quite some time later: E.g. if weston (with the DRM backend)
puts the buffer on a hardware plane, then then buffer release callback is
called when the kernel is done with the buffer. This is usually when the
next frame is shown, so most likely after the frame done callback for the
next frame!

Since 70eff01d36 "wayland: sync() when
destroy()" the mentioned possible leak should no longer be a problem, so
reverting this change should cause no leaking buffers.

5fd4c8dffe wayland: rename is_cancelled to sync_failed
Since commit 065a18a3, the semantics of the variable is_cancelled did not make
sense. This commit renames this variable to sync_failed.

a83057cdb1 wayland: Don't return GST_FLOW_ERROR on flushing
Setting the sink to flushing causes gst_vaapi_window_wayland_sync() to
return FALSE which makes gst_vaapi_window_wayland_render() return
FALSE which ends up posting an ERROR message in
gst_vaapisink_show_frame_unlocked(). Solution is to just return TRUE
in the EBUSY case.

70eff01d36 wayland: sync() when destroy()
Before pushing a the new frame, the render() method calls sync() to flush the
pending frames. Nonetheless, the last pushed frame never gets rendered, leading
to a memory leak too.

This patch calls sync() in the destroy() to flush the pending frames before
destroying the window.

Also a is_cancelled flag is added. This flag tells to not flush the event
queue again since the method failed previously or were cancelled by the user.

11b9260b6c vaapisink: implement unlock/unlock_stop for wayland
Otherwise wl_display_dispatch_queue() might prevent the pipeline from
shutting down. This can happen e.g. if the wayland compositor exits while
the pipeline is running.

Changes:
* renamed unlock()/unlock_stop() to unblock()/unblock_cancel() in gstvaapiwindow
* splitted the patch removing wl_display_dispatch_queue()

522ec79d2e wayland: wl_display_dispatch_queue() can block forever.
wl_display_dispatch_queue() might prevent the pipeline from shutting
down. This can happen e.g. if the wayland compositor exits while the
pipeline is running.

This patch replaces it with these steps:

- With wl_display_prepare_read() all threads announce their intention
  to read.
- wl_display_read_events() is thread save. On threads reads, the other
  wait for it to finish.
- With wl_display_dispatch_queue_pending() each thread dispatches its
  own events.

wl_display_dispatch_queue_pending() was defined since wayland 1.0.2

882387de30 wayland: rename frame for last_frame
Since frame in the private data means the last frame sent, it would
semantically better use last_frame.

Also, this patch makes use of g_atomic_pointer_{compare_and_exchange, set}()
functions.

c80951ada1 wayland: use a counter as sync flag
Wayland window has a pointer to the last pushed frame and use it to set the
flag for stopping the queue dispatch loop. This may lead to memory leaks,
since we are not keeping track of all the queued frames structures.

This patch removes the last pushed frame pointer and change the binary flag
for an atomic counter, keeping track of number of queued frames and use it for
the queue dispatch loop.

62c3888b76 wayland: decouple wl_buffer from frame
This patch takes out the wayland's buffer from the the frame structure. The
buffer is queued to wayland and destroyed in the "release" callback. The
frame is freed in the surface's "done" callback.

In this way a buffer may be leaked but not the whole frame structure.

- surface 'done' callback is used to throttle the rendering operation and to
  unallocate the frame, but not the buffer.
- buffer 'release' callback is used to destroy wl_buffer.

af8ea3701e wayland: refactor _sync() method and rename callback
This patch only intends to improve readability: in the method
gst_vaapi_window_wayland_sync() the if/do instructions are squashed into a
single while loop.

Also renames the frame_redraw_callback() callback into frame_done_callback(),
which is a bit more aligned to Wayland API.

7548c72a7d wayland: free frame in buffer release callback
The Wayland compositor may still use the buffer when the frame done
callback is called.

This patch destroys the frame (which contains the buffer) until the
release callback is called. The draw termination callback only controls
the display queue dispatching.

96ce1bc761 videopool: add optional flags for surface pool allocation.
Reword surface pool allocation helpers so that to allow for a simple
form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a
somewhat more elaborated/flexible form with optional allocation flags
and precise GstVideoInfo specification.

This is an API/ABI change, and SONAME version needs to be bumped.

ff0a237458 window: add generic helper to create windows.
Add a new generic helper function gst_vaapi_window_new() to create
a window without having the caller to check for the display type
himself. i.e. internally, there is now a GstVaapiDisplayClass hook
to create windows, and the actual backend implementation fills it in.
Add new generic helper functions gst_vaapi_texture_new_wrapped()

This is a simplification in view to supporting EGL.

1362352825 wayland: render the raw surface if VPP failed.
As a last resort, if video processing capabilities (VPP) are not available,
or they did not produce anything conclusive enough, then try to fallback to
the original rendering code path whereby the whole VA surface is rendered
as is, no matter of video cropping or deinterlacing requests.

Note: under those conditions, the visual outcome won't be correct but at
least, something gets displayed instead of bailing out.

BT.601, etc.

23c6053b94 wayland: fix frame_redraw callback.
The redraw callback needs to be attached to the surface prior to the
commit. Otherwise, the callback notifies the next surface repaint,
which is not the desired behaviour. i.e. we want to be notified for
the surface we have just filled.

Another isse was the redraw_pending was reset before the actual completion
of the frame redraw callback function, thus causing concurrency issues.
e.g. the callback could have been called again, but with a NULL buffer.
