For muxing, it accepts
both 0 and AV_NOPTS_VALUE. For demuxing, it will present
AV_NOPTS_VALUE when start_time_realtime is unknown.

Currently ff_interleave_packet_per_dts() waits until it gets a frame for
each stream before outputting packets in interleaved order.
Sparse streams (i.e. streams with much fewer packets than the other
streams, like subtitles or audio with DTX) tend to add up latency and in
specific cases end up allocating a large amount of memory.
Emit the top packet from the packet_buffer if it has a time delta
larger than a specified threshold.

This reverts commit 792845e436, reversing
changes made to 1d6666a6b8.
Bumping libavutil requires all libraries that use libavutil to have their
major version bumped (yes breakage has been confirmed this is not a hypotheses)
One case of breakage is due to new types being added to AVOptions and
applications that linked to old libavutil and libswresample
then trying to use old libavutil (its soname changed so the old isnt updated)
and new swresample (its soame didnt change so it is updated)
the new swresample contains AVOption types that the old libavutil doesnt
know of thus the application attempting to access these avoptions
fails
AVOptions are used by all libs so the issue can potentially happen with
any other lib, libswresample was just the first that showed the problem
ive not checked if the other libs are affected currently by the same issue
or not
Also in addition to AVOptions, AVFrames are also defined in
libavutil, bumping it without all libs that use AVFrames could lead to
serious inconsistencies when 2 libs/app end up using 2 different libavutils
The alternative of bumping all is still possible after this revert, if it
turns out to be the preferred solution

Bump libavutil major version to account for the LLS API/ABI changes.
Conflicts:
libavutil/version.h
Bump done to stay compatible with libav, its not neccessary otherwise for ffmpeg
as we have the new ABI/API under LLS2 and the old (unused) under LLS
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Applications that have been linked against an older release of Libav and pick up
updated libraries experience segmentation faults because they pick up the new
libavfilter, which assumes AVFrames have been allocated by libavutil and thus
contain new reference-counting related fields. This will break for AVFrames that
have been allocated by old libavcodec.
All scheduled API changes are deferred to the next bump.
