Unused uniforms are no longer included in the active uniforms list.

Some of the headers in src/mesa/main have pretty common names which
easily conflict with third-party code, e.g. config.h

GLSL sampler variables indicate which texture unit to use for TEX instructions.
Previously, this was baked into the fragment/vertex program and couldn't be
readily changed once set.
Now, SamplerUnits[] array indicates which texture unit is to be used for
each sampler variable. These values are set with glUniform1i().
This is extra state that must be passed to the fragment/vertex program
executor at runtime.

The later takes a type parameter so we can match uniforms or attributes/inputs.
Used by the GL_ACTIVE_ATTRIBUTE_MAX_LENGTH and GL_ACTIVE_UNIFORM_MAX_LENGTH
queries. Fixes problem reported by Brad King in VTK.
