stream: handle mms streaming with ffmpeg

Use ffmpeg (stream_lavf) instead of internal mms support (asf_streaming.c)
for mms://, mmsh://, mmst:// URLs.

The old implementation is available under mp_mms:// etc.

There are some caveats with this:
- mms:// now always maps to mmsh://. It won't try mmst://. (I'm not sure
  if mms:// URLs really can use the mmst protocol, though.)
- MMS streams under the http:// prefix are not handled. (ffmpeg ticket
  #2001.) (Was already broken in mpv since c02f25.)
- It downloads all video streams now. MMS streams often have redundant
  video streams, which encode the main stream at different quality. The
  client is supposed to select one according to its bandwidth
  requirements. (Explicit MMS stream selection has been broken in mpv
  for a while, because MPOpts.vid maps to the stream number, not the
  demuxer's stream ID - but the old logic doesn't work anyway when
  using demuxer_lavf as opposed to demux_asf.)
