Existing av_opt_set_dict doesn't accept flags.
It doesn't allow to pass options to nested structs.
New function alllows that.

Files produced by windows media center contain meaningless mpeg1 sequence
header. The mpeg2 decoder detects the presence mpeg1 sequence header start
codes and attempts to decode the stream as mpeg1. (This problem introduced
in 73a2d16b.)

Fixes ticket #3601.

It is undocumented and has no real use.

That field will be deprecated.

That field will be deprecated and the value that is written there is not
particularly useful.

Also, stop using AVCodecContext.codec_name as fallback, since it will be
deprecated.

Changes the result of the lavf-asf test (and its associated seektest),
since 'msmpeg4v3' gets written instead of just 'msmpeg4'.

That field is undocumented, of dubious use, and will be deprecated.

Stop using the undocumented to-be-deprecated AVCodecContext.codec_name
field.

The addition of reference-counted frames makes it pointless.
