When processing multi-path ip6 routers, place each router entry on its
own line. We made this change in traceroute(8) some time ago. This
is particularly useful when you are not resolving hostnames since ip6
addresses can be quite long, and lines wrap fairly easily in the
multi-path router case.

traceroute6(8) force -w flag (wait time) to be > 1 sec. Make it
possible to use 1 sec wait time.

Use setresuid for simple privilege dropping.

Sync up with KAME. The main change is to try to avoid exposing
exposing information about the endianness and alighment requirements
in the packets sent by traceroute6.

Quote from a Problem Report:

The output format specifier for the round-trip time in ping6 should be
changed to %.3f instead of %g since %g doesn't accurately represent the
precision of the number being output. In particular, %g truncates trailing
zeroes. 0.01 ms does not mean the same thing as 0.010 ms. Although they
are numerically identical, they do not have the same precision.

Correct typos, mostly s/ a / an / where appropriate. Some whitespace cleanup,
especially in troff files.

Back out previous commit. I was a bit overzealous: the fd_set size is
calculated dynamically here.

Check for FD_SET overrun.

This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.
