Merge remote branch 'origin/master' into glsl2

This pulls in multiple i965 driver fixes which will help ensure better
testing coverage during development, and also gets past the conflicts
of the src/mesa/shader -> src/mesa/program move.

Conflicts:
	src/mesa/Makefile
	src/mesa/main/shaderapi.c
	src/mesa/main/shaderobj.h
