a719d3b931 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

f5004fb09b 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.

b223204418 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.
