When using SCTP for sending probe packets, use INIT chunks for payloads
larger than or equal to 32 bytes. For smaller probe packets, keep using
SHUTDOWN-ACK chunks, possibly bundled with a PAD chunk.
Packets with INIT chunks more likely pass through firewalls. Therefore,
use them when possible.

We can also choose a different whois server with the -A switch. The

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:
LBL tcptr Debian (chosen)
ICMP_UNREACH_NET !N !N !N !N
ICMP_UNREACH_HOST !H !H !H !H
ICMP_UNREACH_PROTOCOL !P !P !P !P

Add the capability for traceroute(8) to send packets of any IP protocol
instead of just UDP; an alternate protocol is specified by '-P proto'.
This is useful for finding routers that are blocking packets based on
IP protocol. New handlers can be added fairly easily to do protocol-
specific things.

Paul objected to my previous change. This adds the same functionality
(implemented better, admittedly) with a new option, '-S'. If the
maintainers of traceroute (Van?) add a -S option, we will then be in
conflict.
Also added a too-brief description of the option in the man page. Someone
with a better command of English than I at the moment should probably look
over it and rephrase it.
