Add AS lookup functionality. On each hop we query a whois server to
find the corresponding AS for that IP (-a switch).
We can also choose a different whois server with the -A switch. The
default is whois.radb.net.

Add a -D option to traceroute that prints the differences between
the probe packet we sent and the packet quoted by the ICMP response.
Can be useful for spotting hops that change the packet in-flight
or have problems generating correct ICMP responses.

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

Option for setting a fixed destination port. This is useful for tracing
to a host behind a firewall where only specific services are allowed.
For example, to trace the hops to an HTTP server behind a firewall,

$ traceroute -e -P tcp -p 80 www-firewalled.example.com

Fix minor discrepancy between documentation and implementation: the
destination port is incremented for each packet sent to the same hop.

Add a min TTL flag to go along with the max TTL flag. That is, this flag
allows you to start tracing at a hop number other than 1.

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.

Fix an anomaly in the option descriptions.

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.
