b3461c29c1 lavf: prevent infinite loops while flushing in avformat_find_stream_info 
If no data was seen for a stream decoder are returning 0 when fed with
empty packets for flushing. We can stop flushing when the decoder does
not return delayed delayed frames anymore. Changes try_decode_frame()
return value to got_picture or negative error.

9f9c45f4b6 movenc: Don't require frame_size to be set for modes other than mov 
The field frame_size isn't written to the output anywhere except
than in mov.

fc85729458 mxfdec: Do not parse slices or DeltaEntryArrays.

f028d4d1c3 mxfdec: hybrid demuxing/seeking solution 
This uses the old demuxing code for OP1a and separate demuxing code for OPAtom.
Timestamp output is added to the old demuxing code.

The seeking code is made to seek to the start of the desired EditUnit only,
from which the normal demuxing code takes over (if OP1a). This means we
do not use delta entries or slices, only StreamOffsets. OPAtom seeking
basically works like before.

This also makes D-10 seeking behave the same way as OP1a and OPAtom. In other
words, we allow seeking before the start or past the end for D-10 too.

Based on several patches by Tomas Härdin <tomas.hardin@codemill.se> and
Reimar Döffinger <Reimar.Doeffinger@gmx.de>.

Changed av_calloc to av_mallocz, added overflow checks.
