Thanks Nicolas! The qdata stuff looks very suspicious and should probably be
revisited in 1.6 but it should work that way... just doesn't look very clean :)

    v4l2allocator: Use qdata instead of parenting to DmabufMemory

    Parenting V4l2Memory to DmabufMemory was in conflict with recent
    optimization in DmabufMemory to avoid dup(), and didn't work with
    memory sharing. Instead, use a qdata and it's destroy notify.
