    redirect: use revival and routing code to initiate redirects
    
    This way the revival and redirect code can't get into a fight,
    fixing #1396 and #1319.
    
    - when a redirect arrives, save the redirect details in connection
      .redirect and then trigger an ike family delete (return
      STF_OK_INITIATOR_DELETE_IKE for IKE_SA_INIT and IKE_AUTH, schedule
      DISCARD event for established).
    
    - the routing code sees the +UP connection going down and schedules an
      immediate revival (while also updating kernel state and policy as
      required)
    
    - the revival code sees that it is for a redirect, and acts
      accordingly
    
    When the redirect limit is exceeded, the step saving the redirect
    details is skipped and instead revival is forced to 300s per RFC
    (#1401).  Consequently a normal, if much delayed, revival is
    scheduled.  A failing redirect is the same, but with a more sensible
    delay.
