    pluto: Improve the revive connection code [with D. Hugh Redelmeier]
    
    The previous code used a global variable, and a timer event with 0
    delay. However, it turns out could still compete and lose from other
    timed events, causing unexpected behaviour if those other events also
    touched the global revive connection name.
    
    Instead, use a linked list and ensure no double entries are ever allowed on
    the list.
    
    Additionally, assume that if any IPsec SA comes up, the peer is no longer
    trying to keep their connection down, and reset the delay timer. If the
    peer deletes the connection, then while an IKE SA can come up, the IPsec
    SA should no longer come up. And we can keep trying but with increasing
    delays. Timing changed to adding 5s per attempt up to 5 minutes.
