This integrates support for GStreamer API >= 1.0 only in the libgstvaapi
core decoding library. The changes are kept rather minimal here so that
the library retains as little dependency as possible on core GStreamer
functionality.

Drop the following functions that are now obsolete:
- gst_vaapi_context_get_surface()
- gst_vaapi_context_put_surface()
- gst_vaapi_context_find_surface_by_id()
- gst_vaapi_surface_proxy_new()
- gst_vaapi_surface_proxy_get_context()
- gst_vaapi_surface_proxy_set_context()
- gst_vaapi_surface_proxy_set_surface()
This is an API change.
Now that the surface pool is reference counted in the surface proxy wrapper,
we can safely ignore surface size checks in gst_vaapi_decoder_ensure_context().
Besides, this check is already performed in gst_vaapi_context_reset_full().
Introduce gst_vaapi_surface_proxy_new_from_pool() to allocate a new surface
proxy from the context surface pool. This change also makes sure to retain
the parent surface pool in the proxy.
Besides, it was also totally useless to attach/detach parent context to
VA surface each time we acquire/release it. Since the whole context owns
all associated VA surfaces, we can mark this as such only once and for all.
Move GstVaapiVideoMeta from core libgstvaapi decoding library to the
actual plugin elements. That's only useful there. Also inline reference
counting code from GstVaapiMiniObject.
Make sure libgstvaapi core decoding library doesn't include un-needed
dependencies. So, move out GstVaapiVideoConverterGLX to plugins instead.
Besides, even if the vaapisink element is not used, we are bound to have
a correctly populated GstSurfaceBuffer from vaapidecode.
Also clean-up the file along the way.
In decode_codec_data(), force initialization of format to zero so that
we can catch up cases where codec-data has neither "format" nor "wmvversion"
fields, thus making it possible to gracefully fail in this case.
Add a new GstVaapiDecoder::decode_codec_data() hook to actually decode
codec-data in the decoder sub-class. Provide a common shared helper
function to do the actual work and delegating further to the sub-class.
Drop GstVaapiDecoderUnit buffer field (GstBuffer) since it's totally
useless nowadays as creating sub-buffers doesn't bring any value. It
actually means more memory allocations. We can't do without that in
JPEG and MPEG-4:2 decoders.
Use gst_element_class_set_static_metadata() from GStreamer 1.0, which
basically is the same as gst_element_class_set_details_simple() in
GStreamer 0.10 context.
Use newer gst_video_overlay_rectangle_get_pixels_unscaled_raw() helper
function with GStreamer 0.10 compatible semantics, or that tries to
approach the current meaning. Basically, this is also just about moving
the helper to gstcompat.h.
Generated source files were missing a dependency on the complete set of
generated header files. e.g. gstvideodecoder.c requires gstvideoutils.h
to build and almost every codec parser source depends on parserutils.h.

Force luma_log2_weight_denom and chroma_log2_weight_denom to zero if
there is no pred_weight_table() that was parsed.
This is a workaround for the VA intel-driver on Ivy Bridge.
g_async_queue_timeout_pop() appeared in glib 2.31.18. Implement it as
g_async_queue_timed_pop() with a GTimeVal as the final time to wait for
new data to arrive in the queue.
There shall be only one place to call decode_current_picture(), and this
is in the end_frame() hook. The EOS unit is processed after end_frame()
so this means we cannot have a valid picture to decode/output at this
point.
Improve robustness when some expected packets where not received yet
or that were not correctly decoded. For example, don't try to decode
a picture if there was no valid sequence or picture headers.
Fix gst_vaapi_decoder_get_surface() to only return frames with a valid
surface proxy, i.e. with a valid VA surface. This means that any frame
marked as decode-only is simply skipped.
If the decoder was not able to decode a frame because insufficient
information was available, e.g. missing sequence or picture header,
then allow the frame to be gracefully dropped without generating
any error.
It is also possible that a frame is not meant to be displayed but
only used as a reference, so dropping that frame is also a valid
operation since GstVideoDecoder base class has extra references to
that GstVideoCodecFrame that needs to be released.
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.
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.
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.
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.
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.
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.
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.

Don't create temporary GstBuffers for all decoder units, even if they
are lightweight "sub-buffers", since it is not really necessary to keep
the buffer data around.
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.
