  Log:
  While walking over the list of interfaces obtained from getifaddrs(3),
  rarpd clobbered any AF_INET information already configured for a given
  interface name, so interfaces with more than one IP address made rarpd
  listen only for the last address out of all IP aliases.
  
  I changed this, so that AF_LINK information is always collected first
  (to ensure the interface name gets its link-layer address associated),
  but while looking for AF_INET addresses, the configuration is cloned
  if there has already been one IP address seen for that interface name.
  
  Thus, rarpd now effectively listens on all subnets.
