Added VDPAU to list of supported formats for HEVC10 and 12 bit formats
also added 42010 bit to surface_parameters and new VDP chroma formats to
VDPAUPixFmtMaps
Add HEVC 420 10/12 Bit and 444 10/12 Bit support for VDPAU
YUV444P10 is defined as the 444 surface with 10bit valid data in LSBs
but H/w returns Data in MSBs Hence if we map output as YUV444p16 it
is filtering out the LSB to convert to p10 format.

Add vdpau_parse_rext_profile and use profile constraint flags to
determine the exact vdp_profile for HEVC_REXT.
If profile mismatch is allowed, select Main profile by default.

Currently the next thread's context is updated from the previous one's
if the codec descriptor is not marked as intra-only. That is not
entirely correct, since that property does not necessarily imply
anything about how a specific decoder implementation behaves.
Instead, use the presence of the update_thread_context() callback to
decide whether an update should be performed. Fixes races in CFHD,
should cause no behaviour change in any other decoders.
add probeaudiostream for get audio stream's codec_name,codec_time_base,
sample_fmt,channels and channel_layout.

Important part of this algorithm is the double threshold step: pixels
above "high" threshold being kept, pixels below "low" threshold dropped,
pixels in between (weak edges) are kept if they are neighboring "high"
pixels.
The weak edge check uses a neighboring context and should not be applied
on the plane's border. The condition was incorrect and has been fixed in
the commit.

Currently, both bsfs used the same CodedBitstreamContext for reading and
writing; as a consequence, the state of the writer's context at the
beginning of writing a fragment is exactly the state of the reader after
having read the fragment; in particular, the writer might not have
encountered one of its active parameter sets yet.
This is not nice and may lead to invalid output even when the input
is completely spec-compliant: Think of an access unit containing
a primary coded picture referencing a PPS with id id (that is known from
an earlier access unit/from extradata), then a new version of the PPS
with id id and then a redundant coded picture that is also referencing
the PPS with id id. This is spec-compliant, as the standard allows to
overwrite a PPS with a different PPS in between coded pictures and not
only at the beginning of an access unit. In this scenario, the reader
would read the primary coded picture with the old PPS and the redundant
coded picture with the new PPS (as it should); yet the writer would
write both with the new PPS as extradata which might lead to errors or
to invalid data being output without any error (e.g. if the two PPS
differed in redundant_pic_cnt_present_flag).
The above scenario does not directly translate to HEVC as long as one
restricts oneself to input with nuh_layer_id == 0 only (as cbs_h265
does: it currently strips away any NAL unit with nuh_layer_id > 0 when
decomposing); if one doesn't the same issue as above can happen.
If one also allowed input packets to contain more than one access unit,
issues like the above can happen even without redundant coded
pictures/multiple layers.
Therefore this commit uses separate contexts for reader and writer.

Commit 601c238854 added support for AV_PKT_DATA_NEW_EXTRADATA, but
only for avcC extradata.
This commit adds support for sps/pps extradata as well. This makes
support consistent for passing new extradata consistent with the
types of extradata that can be passed when initializing the decoder.
