more correct EPZS implementation
much faster halfpel ME
simplifications / reducing duplicate code
4MV in LQ mode

- Added real_pict_num to AVCodecContext, it represent the number of the
  previous encoded frame, usefull when coding with B frames.
- Warning fix in motion_est.c

fixed MC rounding for b frames
fixed hq mode with b-frames

Originally committed as revision 406 to svn://svn.ffmpeg.org/ffmpeg/trunk

mpeg4 b-frame enoding support
removed old, out-commented ratecontrol
reuse motion compensation code between encoding & decoding
prefix newly added global functions with ff_ to reduce namespace polution
b-frame ME (unfinished, but working)
added some comments to mpegvideo.h
do MC on encoding only once if possible
bugs? ;)
