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? ;)

- EPZS ME algo used by default.
- HQ flag activated for ffmpeg.
- Cosmetics ...

mpeg12 decoding optimization

Originally committed as revision 364 to svn://svn.ffmpeg.org/ffmpeg/trunk

SAD functions rewritten (8x8 support & MMX2 optimizations)
HQ inter/intra decission
msmpeg4 encoding bugfix (MV where too long)

q-pel mc support
neither is totally bugfree yet though :(

Originally committed as revision 320 to svn://svn.ffmpeg.org/ffmpeg/trunk

sure it works ok. Also it's slow, so use it only when you _really_ need to
measure quality.
- Fix libavcodec Makefile to enable profiling.

mmx & mmx2 quantizer
c dct permutation bugfix
dont copy input on intra only encodings if it can be avoided
dont draw edges on intra only stuff
