h264: do not pass H264Context to h264_slice_header_parse()
Conflicts:
libavcodec/h264dec.h
Did not merge the h264_slice_header_parse() part. We use a few other
members of H264Context for error checking in that function.

If negative pts are possible for some codecs in ogg then the code needs to be
changed to use signed values.

10- and 12-bit DNxHR use the same DC coefficient decoding process and
VLC table, just with a different shift value. From SMPTE 2019-1:2016,
8.2.4 DC Coefficient Decoding:
"For 8-bit video sampling, the maximum value of η=11 and for
10-/12-bit video sampling, the maximum value of η=13."
A sample file will be uploaded to show that with this patch, things
decode correctly:

In order to avoid possible clipping at the very
beginning. Especially apparent when "alternative"
boundary mode is used.
Adopted from original commit by committer.
The Doxygen command is generated from the list of installed headers,
which may change per configuration (e.g. `--enable-gpl` results in
libpostproc to be built and installed).
HDCD is only encoded in s16@44100Hz. Scan the chain of AVFilterLinks
for any resampling or format conversion/truncation that might cause
problems for the filter and issue warnings.

Issue #5727: gain adjustment should only be applied if matching
gain value from a valid packet in both channels. The existing functions process
each channel separately, so it was not possible.
* New versions of hdcd_process(), hdcd_scan(), hdcd_integrate() named
hdcd_*_stereo() that process both channels together.
* target_gain applied will be the last matching target_gain.
* The old single channel functions remain as an option. They can be
used by: -af hdcd=process_stereo=0.
