- Improve interface list handling. The rtadvd(8) now supports dynamically-
added/removed interfaces in a more consistent manner and reloading the
configuration file.

- Implement burst unsolicited RA sending into the internal RA timer framework
when AdvSendAdvertisements and/or configuration entries are changed as
described in RFC 4861 6.2.4. This fixes issues that make termination of the
rtadvd(8) daemon take very long time.

An interface now has three internal states, UNCONFIGURED, TRANSITIVE, or
CONFIGURED, and the burst unsolicited sending happens in TRANSITIVE.
See rtadvd.h for the details.

- rtadvd(8) now accepts non-existent interfaces as well in the command line.

- Add control socket support and rtadvctl(8) utility to show the RA information
in rtadvd(8). Dumping by SIGUSR1 has been removed in favor of it.

Set WARNS=1 temporarily to unbreak universe.

Options for DNS Configuration) into rtadvd(8) and rtsold(8). DNS
information received by rtsold(8) will go to resolv.conf

- 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.

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

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

- deprecate routes#N, as it is hard to keep consistency with
rtprefixN. accept any number of "rtprefix", "rtrefix0",
..., "rtprefix99".
- deprecate "addrs#N", as it is difficult for users to keep
consistency with "addrN".
accept 100 prefix info in maximum - like "addr", "addr0"
... "addr99". WARNS=2 clean on netbsd.
old configuration file should work just fine.
behavior change:
previously, we rejected "addrN" if there's "addr", and we rejected
"addr" if there is "addrN". now we accept both without problem.
- when an advertised prefix configured from the kernel has been added
or invalidated, notice the change in a short delay.
- when invalidating a prefix, do not bark even if there is
inconsistency about prefix lifetimes.
- wrap more specific route info code into ROUTEINFO.

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.
