Revision Log
* Ported the ffmpeg fDCT functions (mmx and xmm). * Modified the skal's versions a bit to allow rolling loops. * Activated Skal's fDCTs (unrolled versions) for mmx _and_ xmm (old code was ignoring xmm versions) * Removed the SSE2 versions (they'll be back later) * .data -> .rodata * Applied announced asm CodingStyle to the dct dir (I'll have to add a section with the said CodingStyle)
