If the cursor is not yet initialized, MoveNextUniqueMultipleKey is
identical to
MoveFirstMultipleKey(Int32, LockingInfo).
Otherwise, move the cursor to the next non-duplicate key in the
database, and store that key and associated datum and as many
ensuing key/data pairs that can fit in a buffer the size of
BufferSize in
CurrentMultipleKey.
MoveNextUniqueMultipleKey will return false if no non-duplicate
key/data pairs exist after the cursor position in the database.
