The source-level replay_populated/replay_discarded methods and their helpers are no longer called. Remove the now-dead replay methods, the VirtIOMEMReplayData struct, the virtio_mem_for_each_plugged/unplugged_section() helpers (only used by the replay methods), and the virtio_mem_section_cb typedef.
