Tested on i965, classic swrast and gallium (radeon, nouveau, llvmpipe) without
regressions.

Patches that need review: 2, 8, 12-15, 17
  - Patches 2 and 12 were originally written by Jason, so I guess we want
    somebody else to review these besides him.
  - Patches 14-15 were also originally written by Jason, but they have gone
    through plenty of changes so maybe it is okay if only Jason reviews them.
