a09a9cbb40 rtadvd(8): Fix use-after-close in cm_handler_client
cm_send() closes 'fd' on error.  In that case, bail out early without trying to
recv from or close 'fd' again.

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.
