1d16669aca wayland: use a local event queue to avoid lock contention.
This improves performance when rendering several surfaces from within
the same process. e.g. a tee of vaapidecode'd buffers to vaapisink.

96d12f9eb1 wayland: fix thread-safe issues.
The Wayland API is not fully thread-safe and client applications shall
perform locking themselves on key functions. Besides, make sure to
release the lock if the _render() function fails.

1fb25b0853 wayland: really wait until the pending redraw completed.
Introduce gst_vaapi_window_wayland_sync() helper function to wait for
the completion of the redraw request. Use it in _render() function to
actually block until the previous draw request is completed.

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.

087bf30c23 wayland: fix display sharing.
When the Wayland display is shared, we still have to create our own local
shell and compositor objects, since they are not propagated from the cache.
Likewise, we also need to determine the display size or vaapisink would
fail to account for the display aspect ratio, and will try to create a 0x0
window.

ee181d1b85 vc1: cope with latest codecparser changes.
Fix build with newer VC-1 codecparser where dqsbedge was renamed to
dqbedge, and now represents either DQSBEDGE or DQDBEDGE depending on
the actual value of DQPROFILE.

df411e435f vc1: fix size of encapsulated BDU.
Fix size of encapsulated BDUs since GstVC1BDU.size actually represents
the size of the BDU data, starting from offset, i.e. after any start
code is parsed.

This fixes a buffer overflow during the unescaping process.

a68c218c8e vc1: fix decoding of WMV3 videos in AVI format.
The AVI demuxer (avidemux) does not set a proper "format" attribute
to the generated caps. So, try to recover the video codec format from
the "wmvversion" property instead.

b134a97d42 vc1: don't create GstBuffers for all decoder units.
Don't create temporary GstBuffers for all decoder units, even if they
are lightweight "sub-buffers", since it is not really necessary to keep

Implement GstVaapiDecoder.start_frame() and end_frame() semantics so
that to create new VA context earlier and submit VA pictures to the
HW for decoding as soon as possible. i.e. don't wait for the next
frame to start decoding the previous one.

a811a5de3d decoder: optimize and clean decode_step() up.
Avoid usage of goto. Simplify decode_step() process to first accumulate all
pending buffers into the GstAdapter, and then parse and decode units from
that input adapter. Stop the process once a frame is fully decoded or an
error occurred.

cc347cb41e decoder: make decode_step() return once the frame is decoded.
Make sure we always have a free surface left to use for decoding the
current frame. This means that decode_step() has to return once a frame
gets decoded. If the current adapter contains more buffers with valid
frames, they will get parsed and decoded on subsequent iterations.
