Add option to disable any reply not related to a listening socket

2) You *do* realize that this isn't anywhere near sufficient in order
to actually make your machine "invisible", right?  (Hint: What *other*
packets can be sent to a machine to provoke a response?)

Even worse: if you want to pretend that the entire machine is "not there",
you must make the router in front on you reply with an ICMP "destination
unreachable" message.

You can't do sometimes, like in DSL lines where the router in front of
you is an ISP owned DSLAM
