6ca3856894 movenc: Add a separate start_pts 
This fixes calculation of trackDuration if the MOVIentry array
is cleared. This is required by the fragmentation support in the
next patch.

c3af52fa8b dsputil: use vertical component for drawing bottom edge. 
Current code only writes 8 pixels of vertical edge for YUV422, which
causes MC artifacts when subsequent frames use data from that edge.

cdfe94c5ab aacenc: Write correct length for long identification strings. 
When the length is the escape value (15), the new length is calculated by
15 + get_bits(8) - 1.

b8dd555c63 aud: remove unneeded field, audio_stream_index from context 
There is only one stream, so it will always be index 0.
This also allows for removal of the private context.

220506d23f avcodec: add a new codec_id for CRYO APC IMA ADPCM. 
The stereo layout and extradata is significantly different from that in
Westwood IMA ADPCM, so a separate codec_id is warranted.

1381e9bc92 lavc: postpone the removal of AVCodecContext.request_channels. 
Although it has been deprecated for a long time, its intended
replacement (request_channel_layout) is not actually used anywhere, so
request_channels is currently the only way to access that functionality.

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.

44deb9f68d mfxdec: Separate mxf_essence_container_uls for audio and video. 
It is a really bad idea to assign a video codec id
when we have set codec_type to audio and vice versa.

Prevents detection of mp2 in mxf as mpeg2video.
