Add support for optimized versions of the code underlying ReadPixels

(and DrawPixels).  The R200, R128, and Unichrome drivers get support
in this commit.  Other drivers would be easy enough to add for people
that have the cards.

The DRI (CVS) build will need to be updated to account for the new
source files.
