mesa: mesa_bufferiv utility function for buffer objects
Patch adds new function 'mesa_bufferiv' and refactors existing GetActiveUniformBlockiv and GetActiveAtomicCounterBufferiv to use it. corresponding Piglit tests: arb_uniform_buffer_object* arb_shader_atomic_counters* (Many tests hit the corresponding queries.)
