Description

This function is used for moddn operations and builds a new DN out of a new RDN and the DN of the new parent.

The new DN is worked out by adding the new RDN in newrdn to a parent DN. The parent will be the value in newsuperiordn, if different from NULL, and will otherwise be taken from dn_olddn by removing the old RDN. (The parent of the entry will still be the same as the new DN).
