Drop support for Libav

Given that Libav is no longer preferred over FFmpeg on any Linux distros, do we care enough to keep supporting it?

This is a conversation that @markreidvfx and I have been having off-line. At this point there is no reason to act, but only to keep this in mind for the next time there is a serious burden put upon us by Libav-vs-FFmpeg.

Annoying things we've had to deal with recently (I'm editing this list as we go):

  • Libav has no avfilter_graph_dump; the functionality was not added.
  • Libav has no AV_ROUND_PASS_MINMAX in the AVRounding enum; I coded around it. (#175 (closed))

Edit 2018-05-22: We're doing this.

  • Discuss this history in the docs.
  • Remove avresample (which will simplify a bunch of setup.py).
  • AV_ROUND_PASS_MINMAX missing (#175 (closed)).
  • Look at every symbol looked for in setup.py.
  • Strip "FFmpeg/Libav" from all casual use in documentation.
