0cd03c86b4 Fix use of -I and -P at the same time by refactoring so there's only
one set of code which knows how to resize the packet.
Report when we shrink MTU because of an EMSGSIZE return; fix
formatting to let this not look ugly.
Add a few likely MTU's to the table (1480 and 1280).

e33da94c5b configure IPsec policy on sending/receiving socket for bypassing IPsec.
If IPsec default policy is configured for destination
traceroute will never success (because encrypted icmp timexceeded
is unrecognizable).

6f775308a6 Only require half of the responses to indicate that the destination is
unreachable.  This makes traceroute exit when it encounters a Cisco, which
typically does not respond to every other probe (or so) when either there
is no route to the destionation or an access list is blocking the probes.

8164a79fad Check select() return value, and abort the program if an error is
returned.  Otherwise after sending a packet, select() may return
immediately (if there's an error of some sort) and traceroute
solders on, sending more packets with no delay in between. This is
effectively a small flood attack.
