Hiroki Sato 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.
