If the next key/data pair of the database is a duplicate data record
for the current key/data pair, move the cursor to the next key/data
pair in the database, and store that pair in Current.
MoveNextDuplicate will return false if the next key/data pair of the
database is not a duplicate data record for the current key/data
pair. If either the key or the data is partial
DatabaseEntry, its
PartialLen bytes starting
PartialOffset bytes from the beginning
of the retrieved data record are returned as if they comprised the
entire record. If any or all of the specified bytes do not exist
in the record, MoveNextDuplicate is successful, and any existing
bytes are returned.
