DRI2: Add ReuseBufferNotify hook
ReuseBufferNotify hook is called whenever old buffer is reused in DRI2
code.
Driver can use this hook to rewrite the buffer name if hardware requires
shared buffers. Shared buffer might be some hardware limited resources like
framebuffer that is preallocated in boot.
