97c3b2ddff libs: use glib >= 2.32 semantics for mutexes.
Use glib >= 2.32 semantics for GMutex and GRecMutex wrt. initialization
and termination. Basically, the new mutex objects can be used as static
mutex objects from the deprecated APIs, e.g. GStaticMutex and GStaticRecMutex.

1d669a3e12 libs: only export gst_vaapi_*() symbols.
This fixes symbol clashes between the gst-vaapi built-in codecparsers/
library and the system-provided one, mainly used by videoparses/. Now,
only symbols with the gst_vaapi_* prefix will be exported, if they are
not marked as "hidden" to libgstvaapi.

c38c0853eb image: fix GstVaapiImage map and unmap.
Fix gst_vaapi_image_map() to return TRUE and the GstVaapiImageRaw
structure correctly filled in if the image was already mapped.
Likewise, make gst_vaapi_image_unmap() return TRUE if the image
was already unmapped.

5fac9d4b55 videobuffer: fix memory leak for surface and image.
Fix reference leak of surface and image in GstVaapiVideoBuffer wrapper,
thus resulting on actual memory leak of GstVaapiImage when using them
for downloads/uploads from VA surfaces and more specifically surfaces
when the pipeline is shutdown. i.e. vaTerminate() was never called
because the resources were not unreferenced, and thus not deallocated
in the end.

cb0da4ed7a h264: fix picture size in macroblocks.
The picture size signalled by sps->{width,height} is the actual size with
cropping applied, not the original size derived from pic_width_in_mbs_minus1
and pic_height_in_map_units_minus1. VA driver expects that original size,
uncropped.

There is another issue pending: frame cropping information needs to be
taken care of.

9ab3ce2932 codecparsers: always build parserutils first.

parsers (gstvc1parser.c for instance).

9367c8ea58 mpeg2: fix PAR calculation from commit bd11bae.
Invoke gst_mpeg_video_finalise_mpeg2_sequence_header() to get the
correct PAR values. While doing so, require a newer version of the
bitstream parser library.

Note: it may be necessary to also parse the Sequence_Display_Extension()
header.

1e506ad6ee h264: fix incorrect integration of previous commit (4d31e1e).

4d31e1e58a h264: start decoding slices after first SPS/PPS activation.
Only start decoding slices when at least one SPS and PPS got activated.
This fixes cases when a source represents a substream of another stream
and no SPS and PPS was inserted before the first slice of the generated
substream.

f196605fc8 h264: fix interlaced stream decoding with MMCO.
Fix decoding of interlaced streams when adaptive_ref_pic_marking_mode_flag

particular, when field_pic_flag is set to 0, the new reference flags shall

2c13b17cdb h264: add initial support for interlaced streams.
Decoded frames are only output when they are complete, i.e. when both
fields are decoded. This also means that the "interlaced" caps is not
propagated to vaapipostproc or vaapisink elements. Another limitation
is that interlaced bitstreams with MMCO are unlikely to work.

d180a3a9f6 h264: simplify reference picture marking process.
... to build the short_ref[] and long_ref[] lists from the DPB, instead
of maintaining them separately. This avoids refs/unrefs while making it
possible to generate the list based on the actual picture structure.

This also ensures that the list of generated ReferenceFrames[] actually
matches what reference frames are available in the DPB. i.e. short_ref[]
and long_ref[] entries are implied from the DPB, so there is no risk of
having "dangling" references.

e30a518267 h264: fix activation order of picture and sequence parameters.
Delay ensure_context() until we actually need a VA context for allocating
new VA surfaces, and then GstVaapiPictures, but also when a real activation
of a new picture parameter set occurs, thus also implying an activation
of the related sequence parameter set.

The most important thing was to drop the global pps and sps pointers since
they may not have matched the currently activated picture parameter or
sequence parameter sets at the specified decode point.

Anoter positive side-effect is that this cleans up all occurrences of
decode_current_picture() to only keep those useful in decode_picture(),
before a new picture is allocated, or in decode_sequence_end() when
an end-of-stream or end-of-sequence condition occurred.
