traceroute6(8): make WARNS=3 clean

The last big commit: let usr.sbin/ use WARNS=6 by default.

- Add AS lookup functionality to traceroute6(8) as well.
- Support for IPv6 transport for AS lookup.
- Introduce $RA_SERVER to set whois server.
- Support for 4 byte ASN.
- ANSIfy function declaration in as.c.

Tested by: IHANet folks.

Remove the -DFAST_IPSEC from Makefiles again.

This was needed during the IPSEC->FAST_IPSEC->IPSEC transition
period to not break the build after picking up netipsec header
files. Now that the FAST_IPSEC kernel option is gone and the
default is IPSEC again those defines are superfluous.

Commit IPv6 support for FAST_IPSEC to the tree.
This commit includes all remaining changes for the time being including
user space updates.

These IPv6-only tools have no explicit dependency on the INET6 macro.

Switch Advanced Sockets API for IPv6 from RFC2292 to RFC3542
(aka RFC2292bis). Though I believe this commit doesn't break
backward compatibility againt existing binaries, it breaks
backward compatibility of API.
Now, the applications which use Advanced Sockets API such as
telnet, ping6, mld6query and traceroute6 use RFC3542 API.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

Enable use of poll()
