  h264: eliminate low_delay

ff_print_debug_info2() is adjusted to allow a NULL pointer as low_delay.
It's only useful for MPEG codecs with the exception of H264.

And sets frames pkt_dts to AV_NOPTS_VALUE as we do not want lavc/utils
to overwrite the field with incorrect values as the decoder is
asynchronous.

Fixes error:
libavcodec/videotoolbox.c:511:18: error: implicit declaration of function
'CMVideoFormatDescriptionCreateFromH264ParameterSets' is invalid in C99

We haven't had a stable release since the packet_gap addition, so probably it
is worth reworking the option to something that makes more sense to the end
user. Also add burst_bits option to specify maximum length of bit bursts.

Merged-by: NClément Bœsch <u@pkh.me>

This makes h264_find_frame_end() not depend on H264Context anymore.

This helps removing the H264Context from the H264ParseContext.

* commit '98c97994':
  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.

Fixes Ticket 5411

* commit '728d90a0':
  h264: decouple h264_sei from the h264 decoder

Main changes:

- SEI decoding doesn't have access to the debug flag in the codec context so a
  few logging are dropped.

- naming of quincunx_sampling_flag and frame_packing_arrangement_type are kept
  as they are in FFmpeg instead of respectively quincunx_subsampling and
  arrangement_type used in Libav because the former match the specifications.

- don't reset the x264 build info once read in order to fix
  fate-h264-lossless (change by Hendrik)

- H264Context.has_recovery_point and deprecated
  AVCodecContext.dtg_active_format are set after ff_h264_sei_decode()
  based on the SEI state since ff_h264_sei_decode() doesn't have access
  to H264Context anymore.

- frame_packing_arrangement_type is not checked against <= 0 in
  decode_postinit() since it is always read as a positive value with
  get_bits(). This fixes a -Wtype-limits warning by GCC spotted by
  Michael.

Side Notes:

- tested that ffprobe on the file from ticket #3652 still returns 4
  keyframes
- tested that playback from ticket #3063 still works
