Previously, the number of RR types for a single owner name was limited only by the maximum number of the types (64k). As the data structure that holds the RR types for the database node is just a linked list, and there are places where we just walk through the whole list (again and again), adding a large number of RR types for a single owner named with would slow down processing of such name (database node). Add a configurable limit to cap the number of the RR types for a single owner. This is enforced at the database (rbtdb, qpzone, qpcache) level and configured with new max-types-per-name configuration option that can be configured globally, per-view and per-zone.
