lavf: improve handling of sparse streams when muxing
...
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.

Bump major of libavfilter for reference counted buffer API changes.
...
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.
