    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.)
