Cell driver state-setter functions, basic tile get/put, glClear.
The state setting code was mostly just copied from the softpipe driver. The SPUs can now get/put framebuffer tiles from/to main memory and clear them to a given color. Lots of debug code in effect. Tiled framebuffer is displayed in X window via the xmwinsys layer. To enable Cell driver, export GALLIUM_CELL=1
