Native bindings to the EXT_gpu_program_parameters extension.

This extension provides a new set of procedures to load multiple consecutive program environment parameters more efficiently, via a single GL call instead of multiple calls. This will reduce the amount of CPU overhead involved in loading parameters.

With the existing ARB_vertex_program and ARB_fragment_program APIs, program parameters must be loaded one at a time, via separate calls. While the NV_vertex_program extension provides a set of similar functions that can be used to load program environment parameters (which are equivalent to "program parameters" in NV_vertex_program), no such function exists for program local parameters.
