dns_name6_domain - construct host name for reverse lookup

       dns_name6_domain   is   a  low-level  component  of  dns_name6.   It  converts  an  IP  address  such  as
       4321:0:1:2:3:4:567:89ab          into          a          domain          name          such           as
       b.a.9.8.7.6.5.0.4.0.0.0.3.0.0.0.2.0.0.0.1.0.0.0.0.0.0.0.1.2.3.4.IP6.ARPA  and  places  the packet-encoded
       domain name into q.

       q is zero terminated.

       q must have space for DNS_NAME6_DOMAIN bytes.
