86bec9a161 - Fix on AVI and WAV headers based on Nikolai Zhubr patch. 
- Now the properties of the AVIs are correctly shown, but the MP2 audio
isn't playable, it seems the problems is that Fraunhoffer MP3 decoder
included on Windows cannot decode MP2 streams.

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.

d6a4c0b111 * some modifications to allow gcc to compile same code for -fPIC 
- introduced MOVQ_WONE, MOVQ_WTWO
* unrolled put_pixels_clamped_mmx

* added some testing code to disable all these routines (for time measurement)
