This changes the way that SurfaceFlinger's shadow buffer management works such that instead of tracking the size of the shadow queue in the BufferQueue, SF tracks the last frame number it has seen, and passes that into the acquireBuffer call. BufferQueueConsumer then ensures that it never returns a buffer newer than that frame number, even if that means that it must return PRESENT_LATER for an otherwise valid buffer.
