Decoders are supposed to export stream properties in AVCodecContext, the
AVFrame properties are set from those in ff_get_buffer().

This fixes mpeg2video stream copies to mpeg muxer like this:
  ffmpeg -i xdcamhd.mxf -c:v copy output.mpg

Makes it behave similarly to av_stream_add_side_data().

This will allow probing input coded side data, and also forwarding them to the output.

This matches the inclusion of the other hwcontext_<hwaccel>.h headers.
The skipping of the header depending on build flags is already present.

PRId64 and PRIu64 already expand to the complete specifier; adding
another 'd' at the end is wrong and just leads to warnings that say
that only an option like '-frames:v 2d' will be used, although said
option won't be accepted at all ('Expected int64 for frames:v but found
2d').

Only top-left chroma position supported for now.

It is not needed at all.

Utilizes a subpicture sample with one decodable subpicture for the
test.

Based on a failing test case in reported by Michael in
https://ffmpeg.org/pipermail/ffmpeg-devel/2019-February/240398.html
which at the time had no test case for it.

Additionally, this is the first test case for the presentation
graphics format.

Each time the sub2video structure is initialized, the sub2video
subpicture is initialized together with the first received heartbeat.
The heartbeat's PTS is utilized as the subpicture start time.

Additionally, add some documentation on the stages.

There are no failure cases left in this function.
