    connections: connection_down() -> connection_unroute()
    
    The terminate*() functions down a connection (i.e., clear UP bit)
    while the connection_down() functions unroute the connection
    (calling connection_down() with an up connection passerts()).
    
    Also merge group route/unroute calls so that connection_unroute()
    can handle connection groups (which happens during shutdown).
