Andreas Rheinhardt 03b04eef72 avformat: Enforce one-stream limit where appropriate
Several muxers (e.g. pcm muxers) did not check the number
of streams even though the individual streams were not
recoverable from the muxed files. This commit changes
this by using the FF_OFMT_MAX_ONE_OF_EACH flag
where appropriate.
