use the dns_qpmulti-based "qpzone" by default throughout BIND, instead of the existing dns_qp-based "qp", when creating zone databases. (cache databases still use "qp".) the "--with-zonedb" option has been updated in configure.ac to permit the use of both "qp" and "qpzone" databases. in zone.c there was a test that prevented any database type other than "qp" from hosting an RPZ. this was outdated, and has been removed.
