changes include:
- do not chase header if ip/ip6 datagram is framgented, and it is not the
first fragment
- u_short -> u_int16_t
- buffer boundary checks, including sprintf -> snprintf
- cleanup truncated packet cases
- pull tcpdump.org enhancements/corrections for RIP, IPv6 options, ICMPv6,
OSPFv3, IPv4 options, BGP

and reachover makefile.
- more length overflow check for ip6 related parsing
- protocol decode fixes
- add dhcp6 parser
