cc13bc8c4f avcodec/h2645: Fix NAL unit padding
The parser changes have lost the support for the needed padding, this adds it back
Fixes out of array reads

5c2fb561d9 h264: add H264_ prefix to the NAL unit types
This will prevent conflicts e.g. in code that deals with both h264 and
hevc.

f638b67e57 h264: move the parameter set definitions to a new header file
The PS parsing code is independent from the decoder, so it makes more
sense for it to have its own separate header.

251cbb4400 h264: create a new header for common h264 definitions
Move the NAL unit types into it. This will allow to stop including the
whole decoder-specific h264dec.h in some code that is unrelated to the
decoder and only needs some enum values.

9df889a5f1 h264: rename h264.[ch] to h264dec.[ch]
This is more consistent with the naming of other decoders.

  h264: decouple extradata parsing from the decoder

Main changes:

- move get_avc_nalsize() inside h264_parser.c and make it use
  H264ParseContext instead of H264Context. This helps fixing
  fate-flv-demux.

- Also use is_avc/nal_length_size from the H264ParseContext in various
  places instead of the H264Context one as that's the fields now filled
  by ff_h264_decode_extradata()

- h264_parse: dont fail decode_extradata_ps() due to nal split failure.
  Change by Michael to fix decoding of h264/ref_10.avi.

b16e9b9ac9 h264: move initialising the explicit pred weight table for MBAFF
Currently it's done in the code that initialises the ref list for
MBAFF, which is not a logical place for it. Move it to the function that
parses the pred table from the bitstream, which is analogous to what is
done for the implicit weight table as well.
