[FFmpeg-cvslog] AVOptions: deprecate av_opt_set_defaults2

[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Sun Sep  4 11:42:41 2011 +0200| [79eff9132581af69fbbd2674337b75fad29aa306] | committer: Anton Khirnov

AVOptions: deprecate av_opt_set_defaults2

It's a hack which was created to allow for multiple options with
different defaults to refer to same field (e.g. 'b' vs 'ab'). There is
no need for it anymore.
