Several fp and vp tweaks:
- Renumber VERT_RESULT_* values so that they match the
numbers of the corresponding FRAG_ATTRIB_ values.
- Add ctx->VertexProgram._Current and FragmentProgram._Current
values which point to either the current client-supplied
program if enabled, or otherwise to the current mesa-internal
program. Thus this program is always the correct one for
the current state, providing that the mesa flags to turn on
automatic generation are enabled.
- Add callbacks to ctx->Driver.BindProgram() in texenvprogram.c
and t_vp_build.c so that the driver knows when the generated
program changes. This is cleaner than trying to code all the
possible _NEW_* flags into the driver, and more precise as well.
- Add a UsesKill flag to identify fragment programs with that
instruction, as these can require special treatment.
- Move the FRAG_OUTPUT values to mtypes.h, near to similar defn's.
