8cdd0a8091 Remove RA timer on an interface with !IFF_UP actively after starting to send
clean-up RA messages for shutting down.  The RA timers could prevent the rtadvd
daemon from shutting down because ra_output() just ignored !IFF_UP interfaces
and TRANSITIVE->UNCONFIGURED state transition never happened due to it.

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.

6f74a8c7a0 Properly convert bit value to a bit field. Before we were storing
values like 0x80 or 0x40 into a uint8_t foo:1 bitfield.  This would
result in the bit always being 0.  One of these caused a warning for
overflow (one that was 0x80), but the other didn't.  They were both
wrong.

This is why I hate code that mixes c struct bitfields and #defines.
The rest of the fields accessed by the program should be audited.

fc35a81b09 - supported a string notation for xxflags.
- 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.
