  Log:
  Make traceroute decode all the ICMP unreachable messages defined
  in http://www.iana.org/assignments/icmp-parameters. Thankfully
  IANA's list aggrees with <netinet/ip_icmp.h>.
  
  I've tried to do this in a way which is mostly consistent with
  tcptraceroute and Debian's version of traceroute. However, sometimes
  a letter is used twice by these versions, so I've gone with:

  Graham Wilson is planning to use the same codes in Debian's version.
