    xa: add XA state tracker based EXA
    
    Currently just for solid fills and blits (no composite wired up yet),
    but this is enough to accelerate presentation blit (and avoid stalling
    for GPU to complete and memcpy), which is pretty important for
    performance of post-sub-buffer (gnome-shell and window managers),
    windowed GL apps (including gpu based video rendering), etc.
