This pulls in multiple i965 driver fixes which will help ensure better
testing coverage during development, and also gets past the conflicts
of the src/mesa/shader -> src/mesa/program move.
Conflicts:
src/mesa/Makefile
src/mesa/main/shaderapi.c
src/mesa/main/shaderobj.h
Check FEATURE_GL in _mesa_init_shader_dispatch and
_mesa_init_shader_uniform_dispatch. OpenGL ES can not and does not use
_mesa_init_<...>_dispatch. This is supposed to be temporary. Ideally,
a more flexible way for initializing dispatch tables should be
developed.
These 3 fields are per shader-program. Copy them into the geometry
program at link time for convenient access later.
Also, add some missing glGetProgramiv() queries.
