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
Fixes: 03ea21d271abc8acf428d42ace51d8b4/asan_heap-oob_3358eef_5692_16f0cc01ab5225e9ce591659e5c20e35.mkv

58640fe89e h264: handle frame recovery in h264_field_start() 
This is a more appropriate place for this. H264Context.recovery_frame is
shared between frame threads, so modifying it where it is right now is
invalid.

e26c64148b h264: discard slices of redundant pictures right after parsing the slice header 
Going through the whole decoder initialization process for a slice we
are not going to decode is unnecessary and potentially dangerous.

606fb6c032 h264: call the hwaccel frame_start() from h264_field_start()

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.
