[TRAFODION-1850] First N operator no longer returns extra rows.
This also fixes [TRAFODION-908].
This is the entire or a partial fix to the problem where
a select [first n] * from udf(...) can return more than n rows.
The problem was that neither FirstN nor the UDF operator fully
implemented the GET_N protocol. While that may be ok for the UDF,
the FirstN needed a fix.
