To make the best use of existing code, I generalised the wrapper
that currently does yuv420p10 to p010 to support any mixture of
input and output sizes between 10 and 16 bits. This had the side
effect of yielding a working code path for all yuv420p1x formats
to p01x.

The allocated size of sc->ctts_data is
(st->nb_index_entries + entries) * sizeof(*sc->ctts_data).
The size to memset at offset sc->ctts_data + sc->ctts_count should be
(st->nb_index_entries + entries - sc->ctts_count) *
sizeof(*sc->ctts_data))
The current code missed |entries| I believe, which was introduced in
https://patchwork.ffmpeg.org/patch/5541/.
However, after offline discussion, it seems the original code is much
more clear to read (before https://patchwork.ffmpeg.org/patch/5541/).
Hence this CL revert the memset logic to it's previous state by
remembering the |old_ctts_allocated_size|, and only memset the newly
allocated entries.

Obviously this is still not perfect, but better then it was. Using the first
index table and mxf->current_edit_unit is still hardcoded in many places, so
this change has hopefully the less chance of breaking anything that works
now.

Use body_offset of the partitions to search for the partition with the given
offset in the essence. This makes the function find the correct partition for
non frame-wrapped essences as well, where only the essence data is part of the
the edit unit byte count, not the KLV-s.

In order to do that we have to parse the EssenceContainerData and assign the
proper body_sid and index_sid to the tracks from the corresponding source
packages.
This fixes packets returned in the wrong stream for some OP1-b files.

This patch makes it possible to dinamically close the current segment
and step to the next one by introducing command handling capabilities
into the filter. This new feature is very usefull when working with
real-time sources or live streams as source. Combinig usage with zmqsend
tool you can interactively end the current segment and step to next one.

External headers are no longer welcome in the ffmpeg codebase because they
increase the maintenance burden. However, in the NVidia case the vanilla
headers need some modifications to be usable in ffmpeg therefore we still
provide them, but in a separate repository.
The external headers can be found at
https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git
Fate-source is updated because of the deleted files, and dynlink_loader.h
license headers were updated with the standard FFmpeg headers.
