rtsold does not need to link to libkvm

Convert usr.sbin to LIBADD
Reduce overlinking

Lower WARNS level to 3 to eliminate alignment warnings related to
casting inherent in CMSG_DATA().

Remove redundant assignments to WARNS.

For these directories, WARNS is already implied to be 6.

- Implement RDNSS and DNSSL options (RFC 6106, IPv6 Router Advertisement
Options for DNS Configuration) into rtadvd(8) and rtsold(8). DNS
information received by rtsold(8) will go to resolv.conf(5) by
resolvconf(8) script. This is based on work by J.R. Oldroyd (kern/156259)
but revised extensively[1].

- rtadvd(8) now supports "noifprefix" to disable gathering on-link prefixes
from interfaces when no "addr" is specified[2]. An entry in rtadvd.conf
with "noifprefix" + no "addr" generates an RA message with no prefix
information option.

- rtadvd(8) now supports RTM_IFANNOUNCE message to fix crashes when an
interface is added or removed.

- Correct bogus ND_OPT_ROUTE_INFO value to one in RFC 4191.

rtsol(8)/rtsold(8): make WARNS=3 clean

It is actually WARNS=6 clean for non-strict alignment archs.

Approved by: ed (co-mentor)

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

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

Tested with: cmp(1)

support poll(2).

style.Makefile(5)

Add -DHAVE_ARC4RANDOM to CFLAGS

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.

Sync with recent KAME.
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.
