    meta: Only clear the requested color buffers.

    This path is used to implement both glClear and glClearBuffer; the
    latter is only supposed to clear particular buffers.  Core Mesa provides
    us that information in the buffers bitmask; we must only clear buffers
    mentioned there.

    To accomplish this, we save/restore the color draw buffers state, and
    use glDrawBuffers to restrict drawing to the relevant buffers.

    Fixes Piglit's spec/!OpenGL 3.0/clearbuffer-mixed-formats and
    spec/ARB_framebuffer_object/fbo-drawbuffers-none glClearBuffer tests
    for drivers using meta clears (such as Broadwell).
