* 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)
 *  - Inverse DCT header  -
