s4-dns: a dlz module for bind9

this module can be loaded into bind9 if bind9 has been built with the
--with-dlz-dlopen option. It provides access bind9 access to the
DNS records in SAMDB.

You can then start bind9 with this in named.conf:

dlz "Samba zone" {
	database "dlopen /usr/lib/samba/modules/bind9/dlz_bind9.so";
};

See http://git.samba.org/tridge/bind9.git for a bind9 tree with the
dlz_dlopen driver. See also the discussion on the bind-workers mailing
list
