Anton Khirnov e0da916b8f fftools/ffmpeg: optimize inter-thread queue sizes
Use 8 packets/frames by default rather than 1, which seems to provide
better throughput.

Allow -thread_queue_size to set the muxer queue size manually again.

Anton Khirnov 5c5140ded2 fftools/ffmpeg_sched: track dts+duration as last_dts
This should be slightly (probably negligibly) more accurate for
scheduling, but mainly it improves the final reported time.

Anton Khirnov 9b8cc36ce0 fftools/ffmpeg: add thread-aware transcode scheduling infrastructure
See the comment block at the top of fftools/ffmpeg_sched.h for more
details on what this scheduler is for.

This commit adds the scheduling code itself, along with minimal
integration with the rest of the program:
* allocating and freeing the scheduler
* passing it throughout the call stack in order to register the
  individual components (demuxers/decoders/filtergraphs/encoders/muxers)
  with the scheduler

The scheduler is not actually used as of this commit, so it should not
result in any change in behavior. That will change in future commits.
