2989. [func] Added support for writable DLZ zones. (Contributed

by Andrew Tridgell of the Samba project.) [RT #22629]

2988.	[experimental]	Added a "dlopen" DLZ driver, allowing the creation
			of external DLZ drivers that can be loaded as
			shared objects at runtime rather than linked with
			named.  Currently this is switched on via a
			compile-time option, "configure --with-dlz-dlopen".
			Note: the syntax for configuring DLZ zones
			is likely to be refined in future releases.
			(Contributed by Andrew Tridgell of the Samba
			project.) [RT #22629]

2987.	[func]		Improve ease of configuring TKEY/GSS updates by
			adding a "tkey-gssapi-keytab" option.  If set,
			updates will be allowed with any key matching
			a principal in the specified keytab file.
			"tkey-gssapi-credential" is no longer required
			and is expected to be deprecated.  (Contributed
			by Andrew Tridgell of the Samba project.)

[RT #22629]
2986. [func] Add new zone type "static-stub". It's like a stub
zone, but the nameserver names and/or their IP
addresses are statically configured. [RT #21474]
