change

   setup_mirror_symmetry_ghost_zone()
   setup_periodic_symmetry_ghost_zone()
   setup_interpatch_ghost_zone()
   setup_patch_frontier()
to all return references to newly-created objects
... n.b. references are to most-derived types (eg interpatch_ghost_zone
not just ghost_zone) for the benefit of
   patch_system::setup_adjacent_patch_frontiers()
