Components and pieces are side data specific fields and there's a variable
amount of them.
They also need to be identified in some form, so print a type too.

Some encoders, like flac, propagate updated extradata at the end of encoding
as packet side data. Use it to update the relevant codec_config.

Fixes errors when opening streams with no extradata (like those from raw OBU
sources). It also calls get_format() on new Sequence Headers when required.

Export each tile as its own stream, and the grid information as a Stream Group
of type TILE_GRID.
This also enables exporting other stream items like thumbnails, which may be
present in non tiled HEIF images too. For those, the primary stream will be
tagged with the default disposition.

The output of TX is extremely verbose and makes it harder to find other debug

Also, move it to MPEGTS_OPTIONS while at it to avoid duplication.

The avctx passed to avcodec_string() may have unset coded dimensions, as is the
case when called by av_dump_format() where the streams had all the needed
information at the container level, and as such no frames were decoded
internally.

The existing (and upcoming) available group types are meant to combine several
streams for presentation, with the result being treated as if it was a stream
itself.
For example, a file could export two stream groups of the same type with one of
them as the "default".

Ensure all hwaccels that allocate a buffer use NVDECContext->bitstream_internal
instead. Otherwise, if FFHWAccel->end_frame() isn't called before
FFHWAccel->uninit(), an attempt to free a stale pointer to memory not owned by
the hwaccel could take place.
