 doesnt use ugly macro wraper

855ea723b0 * two functions to handle allocation of static data more simple 
av_mallocz_static - called for every static data table
  av_free_static - called when ffmpeg is no longer needed and should free
                   all static resources
* simple usage shown in mpegaudiodec.c

4b1f4f236b - Versions defined for libav/libavcodec.

10bb7023a2 - Added force_pts to av_write_packet() to be able to force PTS, this helps 
(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.
