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.

[bug] More TKEY/GSS fixes: - nsupdate can now get the default realm from the user's Kerberos principal - corrected gsstest compilation flags - improved documentation - fixed some NULL dereferences [RT #22795] 3003. [experimental] Added update-policy match type "external", enabling named to defer the decision of whether to allow a dynamic update to an external daemon. (Contributed by Andrew Tridgell.) [RT #22758] 2991. [contrib] contrib/zone-edit.sh: A simple zone editing tool for dynamic zones. [RT #22365] 2992. [contrib] contrib/check-secure-delegation.pl: A simple tool for looking at a secure delegation. [RT #22059] 3005. [port] Solaris: Work around the lack of gsskrb5_register_acceptor_identity() by setting the KRB5_KTNAME environment variable to the contents of tkey-gssapi-keytab. Also fixed test errors on MacOSX. [RT #22853] 2948. [port] MacOS: provide a mechanism to configure the test interfaces at reboot. See bin/tests/system/README for details.
