59c9dc82f4 avformat/avformat: Move AVOutputFormat internals out of public header 
This commit does for AVOutputFormat what commit
20f9727018 did for AVCodec:
It adds a new type FFOutputFormat, moves all the internals
of AVOutputFormat to it and adds a now reduced AVOutputFormat
as first member.

This does not affect/improve extensibility of both public
or private fields for muxers (it is still a mess due to lavd).
