    pluto: negotiate_hash_algo_from_notification() prevent buffer overrun; tidy
    
    - if the Other Side sent a payload listing too many hash algorithms,
      an internal buffer would overflow.  Now a diagnostic will be issued.
      Is the diagnotic emitted via the correct routine?
    
    - reduced the scope of local variables
    
    - eliminated pointless initialization
    
    - moved common code outside the switch cases
    
    - fixed typo in comment
