DMA stuff

After having a looong read through the MFC documentation, i finally came up with something what looks like double buffered huffman stream.

The good thing, all that dma stuff doesn't compromised decompression speed.
So far 1024x768 image takes <15 msec to decompress.
This is 3 times faster than scalar prototype on my Athlon.

Not very bad for poor little SPE ;)
