Andreas Rheinhardt 37f0dbbc39 avformat: Enforce codec_id where appropriate
E.g. chromaprint expects to be fed 16bit signed PCM
in native endianness, yet there was no check for this.
Similarly for other muxers. Use the new
FF_OFMT_FLAG_ONLY_DEFAULT_CODECS to enfore this where
appropriate, e.g. for pcm/raw muxers.

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.

Andreas Rheinhardt 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).

Marton Balint 4bf90e095b avformat: remove avio_flush() calls from the end of write_header functions
To make it consistent with other muxers.

The user can still control the generic flushing behaviour after write_header
(same way as after packets) using the -flush_packets option, the default
typically means to flush unless a non-streamed file output is used.

Therefore this change should have no adverse effect on streaming, even if it is
assumed that the first packet has a clean buffer, so small seekbacks within the
output buffer work even when the IO context is not seekable.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.
