ffmpeg: get rid of new* options.

Browse Source 
They are confusing, irregular and redundant -- -map already contains all
the information.  Stream maps can now be parsed in opt_output_file().

Add a more user-friendly default behavior in case no maps are present.

Breaks -programid for now, but it never worked properly anyway. A better
solution will be written soon.
