create dns_qpmulti-based zone database
create a dns_qpmulti-based zone database implementation, and use it as the default for all databases with zone semantics.
the RBTDB still exists and can be switched on using the database
option in a zone
statement, or made the default by using configure --with-zonedb=rbt
.
This is part of GL #4348 (closed).
