For enable BufferAge support, we just have to be not using the DRI2Buffer->flags field for any purpose (i.e. it is always expected to be 0, as it is now) and to be sure to swap the flags field whenever we exchange buffers. As nouveau does not exactly support TripleBuffer, we don't have to worry about setting the copying the flags field when injecting the third buffer.
