Remove exit_picture() and exit_picture_poc() since PicOrderCnt(CurrPic)
is now updated accordingly to the standard. Besides, MMCO = 5 specific
operations are moved up to exec_ref_pic_marking_adaptive_mmco_5().
Fix adaptive memory control decoded reference picture marking process
implementation for operations 2 to 6, thus also fixing support for
long-term reference pictures.
This change only splits each individual MMCO handler into several functions
dedicated for each operation. This is needed to perform further work later
on.
Allow build with strict DPB ordering mode whereby evicted entries
are replaced by the next entries, in order instead of optimizing
it away with the last entry in the DPB.
This is only useful for debugging purpose, against a reference SW
decoder for example.
GstH264SliceHdr.n_emulation_prevention_bytes is bound to exist now that
a newer version of codecparsers/ are used if the system provided one is
now recent enough to have those required extensions.
Use newer sources from the codecparsers/ submodule for
- GstH264SliceHdr.n_emulation_prevention_bytes: EPBs;
- GstH264VUIParams.{par_n,par_d}: pixel-aspect-ratio.
Propagate pixel-aspect-ratio determined by the GStreamer codecparser
from the sequence headers.

Split decode_buffer() into the core infrastructure that determines
the NAL units contained in the adapter and the actual function that
decodes the NAL unit.
Split decode_buffer() into the core infrastructure that determines
the packets contained in the adapter and the actual function that
decodes the packet data.
Fix memory leakage of empty packets, i.e. packets that only contain
the start code prefix. In particular, free empty user-data packets.
Besides, the codec parser will already fail gracefully if the packet
to parse does not have the minimum required size. So, we can also
completely drop the block of code that used to handle packets of size 4
(including the start code).
Fix return value when the second scan for start code fails. This means
there is not enough data to determine the full extents of the current
packet and the function shall return GST_VAAPI_DECODER_STATUS_ERROR_NO_DATA
in this case, instead of GST_VAAPI_DECODER_STATUS_SUCCESS.
Improve the semantics for gst_vaapi_decoder_put_buffer() when an empty
buffer is passed on. An empty buffer is a buffer with a NULL data pointer
or with a size equals to zero. In this case, that buffer is simply
skipped and the function returns TRUE. A NULL buffer argument still
marks the end-of-stream.
Rather than always making the surface fullscreen instead implement the
set_fullscreen vfunc on GstVaapiWindow and then set the shell surface
fullscreen on not depending on that.

Mesa recently updated the <GL/glext.h> header version to Khronos version 85.
This caused the PFNGLMULTITEXCOORD2FPROC definition to be moved out of the
GL_VERSION_1_3_DEPRECATED block. However, since <GL/gl.h> also defines
GL_VERSION_1_3 to 1, the definitions in <GL/glext.h> are then not enabled,
thus leaving PFNGLMULTITEXCOORD2FPROC undefined as well.
Provide a PFNGLMULTITEXCOORD2FPROC replacement as an interim solution for
newer versions of the <GL/glext.h> header.
Maintaining the sub-buffer is rather suboptimal especially since we
were also maintaining a GstAdapter. Now, we only use the GstAdapter
thus requiring minor extra parsing when receiving avcC buffers.
This allows the compositor to optimize redraws and cull away changes
obscured by the video surface.

Reset, i.e. destroy then create, the decoder in _setcaps() handler only
if the underlying codec type actually changed. This makes it possible
to be more tolerant with certain MPEG-2 streams that get parsed to
form caps that are compatible with the previous state but minor changes
to "codec-data".
Make it possible to specify the maximum number of references to use within
a single VA context. This helps reducing GPU memory allocations to the useful
number of references to be used.
Forward declaring enums is not allowed by the C standard and aborts
compilation if the header file is included in a C++ project.

Some VA drivers (e.g. EMGD) can have completely random values for initial
display attributes. So, try to improve the discovery process to check the
initial display attribute values actually fall within valid bounds. If not,
try to reset those to some sensible values like the default value reported
through vaQueryDisplayAttributes().
