6baefd92e4 sync with recent KAME. 
- more length overflow check for ip6 related parsing
- protocol decode fixes
- add dhcp6 parser

XXX how should we maintain usr.sbin/tcpdump for years to come?
relationship with www.tcpdump.org codebase?

a7c7586cf6 First part of ARCnet support. 
Matching for anything won't work (as we need to teach the stuff about
variable length link level headers), but printing is fine.

00cef679df New ARP system, supports IPv4 over any hardware link. 
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

d65ddbd4e0 Grok NFSv3 packets. Needs a bit of work but is ok for now. Enable dumping 
of NFS packets over TCP. Upgrade to 3.0.4 while at it. 3.0.4 fixes previous
fix made to util.c too; 'official' fix applied instead (very minor difference).

Fixes to be sent to maintainers RSN.
