7a7a6331a9 Fix a bug in the TCP tracerouting which resulted in not accepting any
incoming packets. So all packets seemed to be lost.

4b9414ab92 For some reason, contrib/traceroute/traceroute.c ensures MAXHOSTNAMELEN
is defined, but then proceeds to use a hardcoded maximum hostname length
of 64 anyway.  Fix this by checking against MAXHOSTNAMELEN instead.

8ea0d8cff1 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.

2f87bd055e Add a -D option to traceroute that prints the differences between
the probe packet we sent and the packet quoted by the ICMP response.

e4ad3d8dd8 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:
