uint32 array index -> segv), so let's just use a nice plain
unobfuscated version, which also happens to be faster for me.

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? ;)

43f1708f8b - Added PSNR feature to libavcodec and ffmpeg. By now just Y PSNR until I'm 
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.
