    sna/dri2: Move scanout processing from frame event to global

    The scanout is a global property, track it as so. The primary benefit to
    this is it strengthens our assertions that we never hand out an active
    scanout for use as a back buffer.

    sna/dri2: Defer reallocation of backbuffer until request

    If we defer the reallocation of the backbuffer until the client requests
    the set of current buffers (with GetBuffers), then we can often avoid
    allocating the fresh backbuffer as the flip often retires before the
    client is ready.

Can I ask if you can also compile with --enable-debug (if you haven't already)?
