Evan HuntandMatthijs Mekking 92b305be4b add a compile-time option to select default zone and cache DB
by default, QPDB is the database used by named and all tools and
unit tests. the old default of RBTDB can now be restored by using
"configure --with-zonedb=rbt --with-cachedb=rbt".

some tests have been fixed so they will work correctly with either
database.

CHANGES and release notes have been updated to reflect this change.
