ffmpeg: use timestamp from before and after the decoder to detect backward moving dts for discontinuity detection
This should make discontinuity detection more robust and detect
more cases. Timestamps after the decoder can be delayed due to threads,
timestamps before can be missing
no testcase available/known

ffmpeg: ensure that -fix_sub_duration doesnt create subtitles with zero duration
When fix_sub_duration is used, and the duration fixing code is generating 0
duration, that is definitely zero, and not undefined or infinite (which may be
the case for decoded AVSubtitles depending on the codec), so it is safe to drop
it.
It fixes teletext subtitle sources, when the subtitles are transmitted twice
after each other for some reason.

ffmpeg: free empty subtitles as well in transcode_subtitles
Even if it does not matter at the moment, because subtitles with num_rect == 0
have no memory allocated, this is how we expect the users to use the API, a
returned AVSubtitle should be freed with avsubtitle_free.

ffmpeg: Do not fill gap before the first decodable frame on single stream input files unless the user explicitly requests it.
Fixes different behavior to JM and probably several if not all
reference decoders.
We cannot just do this unconditionally as it would ruin AV sync in
some use cases.

ffmpeg: treat avi as VFR in framerate conversion code
It can be debated if avi is vfr or cfr, it can be either depending
on the definition of vfr and cfr.
This commit ensures that avi is treated correctly independent of
the AVFMT_VARIABLE_FPS value.
