    ddns: handle re-orienting and re-routing locally
    
    Drop update_host_pair() call, to add to "???"'s comments:
    
    - it was trying to avoid DNS lookups, yet the first thing it did was a
      DNS lookup
    
    - it updated SPDs by scribbling on them, yet the caller was already
      updating SPDs and not scribbling on them
    
    - it unrouted, but never rerouted; for the first connection it
      unrouted after the caller had updated SPDs
    
    - it never initiated so only the first updated connection restarted
    
    ref #1410

    ddns: move half the DDNS code to ddns.[hc]
    
    That is the half hiding in initiate.[hc].  The other half still
    hides in host_pair.[hc].
