(cherry picked from commit b78c30d7ec)

This is able to modify some header metadata found in the VPS/SPS/VUI,
and can also add/remove AUDs.

(cherry picked from commit b31a9eae02)

This applies a specific fixup to some Blu-ray streams which contain
redundant PPSs modifying irrelevant parameters of the stream which
confuse other transformations which require correct extradata.

A new single global PPS is created, and all of the redundant PPSs
within the stream are removed.

(cherry picked from commit e6874bc3af)

This is able to modify some header metadata found in the SPS/VUI,
and can also add/remove AUDs and insert user data in SEI NAL units.

(cherry picked from commit 9e93001b61)
(cherry picked from commit c42b62d1f9)

Supports all streams that the coded bitstream infrastructure does
(currently H.264, H.265 and MPEG-2).

(cherry picked from commit f11d8a5e8b)

Also enable MPEG-2 support in the trace_headers filter.

Takes a raw input stream containing frames with correct timestamps but
possibly out of order and inserts additional show-existing-frame
packets to correct the ordering.

Partially based on code by Ronald S. Bultje <rsbultje@gmail.com>.

It is useful for testing/debugging and will also be used as the default
filter in the following commit adding pre-decode filtering to avoid
having a separate non-filtered codepath.

- Restored alphabetical order.
- Enhanced sections aac_adtstoasc, dca_core, h264_mp4toannexb.
- Added sections hevc_mp4toannexb and vp9_superframe.
- Renamed (if required) and filled previously empty sections
  mjpegadump, mov2textsub/text2movsub, mp3decomp, and
  remove_extra.
- Fixes ticket #3198.

This is intended as a replacement for the 'split' function exported by
some parsers.

The actual implementation uses ':' divider, not '/' as
documented.

This looks more like a seed than an amount, as the variable name
could lead to think.

The format is now:
-bsf:X filter1[=opt1=str1/opt2=str2],filter2
ie the parameters are appended after the filter name using '='. As ','
has been reserved already for the list of filters, '/' is just an
example of token separation for now, but that could become part of the
API to avoid each bsf using its own tokenization.

The proper solution would be using AVOption, but this is overkill for now.
