update ffmpeg. trying to keep local changes (see diff_to_ffmpeg_cvs.txt), let me
know if i overlooked something. as usual, preliminary QA: tested non debug builds and several codecs including divx3/4/5, mpeg4, xvid, msmpeg4v3, svq1, wmv7, dv (video/audio), wma i also enabled wmv8 by default since it worked fine with the streams i have. i'm not sure about current state of that so we might enable it only for non-x86 users in case of trouble.
