Checkpoint: replacement of TGSI_ATTRIB_x tokens with input/output semantics.

TGSI_ATTRIB_x tokens still present and used in a few places.
Expanded set of TGSI_SEMANTIC_x tokens for describing the meaning
of inputs/outputs.  These tokens are in a crude state ATM.
Lots of #if 0 / disabled code to be removed yet, etc...
Softpipe and i915 drivers should be in working condition but not heavily tested.
