Make traceroute(8) faster by sending probes and doing DNS async.
Traditional traceroute would send one probe and then wait for up to 5
seconds for a reply and then send the next probe. On a lossy link that
eventually ends in a black hole this would take about 15 minutes and
people would hit control-c in anger.
This rewrites the traceroute engine to use libevent and asr's async
DNS interface. Probes are now send every 30ms or as soon as we get an
answer back. With that we got the 15 minute worse case down to about
10 seconds.
A minor adjustment that is possible with this is to delay printing a
line until we get to a line with answers. This has two effects:
1) If there are intermediate hops that don't answer, output pauses for
a bit so we keep the visual cue of "something might be wrong here".
2) If there is a black hole at the end, we don't print out many "* * *"
lines and thus scrolling the interesting bits out of the terminal.
We collapse those lines and just print
64 * * *
at the end.
Unfortunately the -c option to send udp probes to a fixed port had to
go for now. But we should be able to add it back.

rearrange code: traceroute.c now only contains main() and usage(), worker.c contains all other functions, and i tracked down which global variables are used in which file and marked them accordingly with static (or not). No functional change, just the basis of further work. ok florian@, deraadt@

for some time now mandoc has not required MLINKS to function correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

These small setuid programs allocate a resvport, and then immediately revoke privs. Link them static, so that even less code is run before main does that job.
