Add a new video pts tracking mode, enabled by option -correct-pts.

This mode has the following differences:
- Video timing is correct for streams with B frames, at least with some
  demuxers.
- Video filters can modify frame timestamps and insert new frames, and
  removing frames is handled better than before.
- Some things are known to break, it's not usable as the default yet.

Things should work as before when the -correct-pts option is not used.
