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.
