5ffb56f057 In rtadvd, interface lookup calls if_indextoname() many times in a loop,
(it takes a long time on systems with many interfaces)
without reason and without checking its return value.

8afa1c3d7a Use strlcpy() instead of strncpy() when copying ifname to ensure
that it is NUL terminated.  Additional NUL padding is not required
for short names.

3724189620 - 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.

db82af41db - 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.

3384154590 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.

7c991abcbc some clarification on if_getmtu()
- avoid to use freed (by freeifaddrs) data
  - 1st try getifaddrs, then try SIOCGIFMTU as the last resort
