PCSX movie quality fix

Improved MDEC Code This patch resolves a video quality bug in PCSX (and derivatives) and since it is a complete rewrite of the mdec.c file it also allow PCSX to be completely licensed under the GPL.

The rewrite is based on an implementation of the AAN (Y. Arai, T. Agui, and M. Nakajima) IDCT algorithm plus some optimizations based on extra information on the coefficient matrices provided by the RLE decoder.

Matrox Millennium II Xv extension

DVD video on P3 This patch will enhance the 7.1 Matrox Millennium II driver to support the X video (Xv) extension (extremely useful for playing DVDs and other video formats). The extension is implemented as a CPU to Frame Buffer YUV scaling ILOAD. A true overlay was not used because of a Millennium II hardware limitation that would reduce the maximum usable frame buffer to only 4Mb.
