AC3 set avcodec_context->channels to the desired number channels, if the
setting is 0 AC3 decoder will set it to the channels found in the
stream.
- Changed ffmpeg to cope with the new "way" of AC3 decoding.
- ASF muxer now uses Tickers for PTS calculations.

the PIX_FMT_ so they get PIX_FMT_ANY instead of PIX_FMT_YUV420P which
obviuosly annoys ffmpeg.

(and fix) stream copying. By now force_pts it's just honoured by the MPEG
muxer. ASF could honour this also, but it should be fixed to use Tickers
first.
- MPEG audio decoder exports it's frame size in bytes.
- Hope this fix the floating point exception found in ffserver.

untested (no g200 mga or whatever i would need ...)
experimental sse2 version (even less tested as no p4 either ...)
sse2 version would need 16-byte aligned src & dst else sig11
sse2 version is disabled by default
