(Stephane Marchesin, me) add hyperz support to radeon and r200 drivers. Only fast z clear and z buffer compression are supported for now, hierarchical-z is not. Still problems with multiple apps and z/stencil readback, which is why hyperz is disabled per default. Also add the new point sprite packet drm 1.13 accepts to the sanity code.
