[TRAFODION-2190] Problems with CQS and TMUDFs
Control query shape with a Table-mapping UDF caused a core dump.
More generally, there was no syntax for forcing a shape with a
TMUDF. Fixed the core dump and also added a "tmudf" keyword to
CQS. tmudf can be used as a leaf and as a unary operator in CQS
(binary operators may be supported in the future).
