get_addresses()
 . use apr_parse_addr_port() so we handle IPv6 addresses on
   NameVirtualHost and <VirtualHost > directives
 . don't hardcode AF_INET when a hostname or IP address was
   coded

dump_a_vhost()
 . check the address family before looking for certain IPv4
   addresses

ap_fini_vhost_config()
 . pass apr_status_t to ap_log_error() after apr_getnameinfo()
   fails
