JIRA TRAFODION-2834 Streamline supported xn access modes

traf DTM only supports 'read committed access' for selects

and 'set transaction ' stmts.

With this checkin, only those 2 options will be allowed.

All other access options will return an error.

Read uncommitted access will be treated as read committed.

[TRAFODION-2727] Memory leak in the compiler part of the code in Trafodion

Compiler objects were refactored to use the heap infrastructure to ensure

that it is accounted and allocated within the trafodion memory management.

The commonly used NAType and derived classes are mostly created via heap,

but the heap was not passed in the constructor. The embedded objects

used the system heap though the container object is allocated in the compiler

heap. This could result in memory leak when the container object is

destroyed.
