  Modified files:
    sys/sys              param.h 
    sys/netinet          ip_fw2.c ip_icmp.h 
  Log:
  Introduce a struct icmphdr which contains the type, code, and cksum
  fields of an ICMP packet.
  
  Use this to allow ipfw to pullup only these values since it does not use
  the rest of the packet and it was failed on ICMP packets because they
  were not long enough.
  
  struct icmp should probably be modified to use these at some point, but
  that will break a fair bit of code so it can wait for another day.
  
  On the off chance that adding this struct breaks something in ports,
  bump __FreeBSD_version.
