mesa: add new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputs

Browse Source 
Previously, the FOGC attribute contained the fragment fog coord, front/back-
face flag and the gl_PointCoord.xy values.  Now each of those things are
separate fragment program attributes.  This simplifies quite a few things in
Mesa and gallium.

Need to test i965 driver and fix up point coord handling in the gallium/draw
module...
