Stack corruption due to pointer type mismatch

Determine if this needs fixing. The comment was from 2017-09-10 and shows that it has not been resolved.

See: https://sourceforge.net/p/exip/bugs/19/

Passing SmallIndex pointer (&pfxEntryId) to Index pointer argument in createUriTableEntry() for the addPfxEntry() call causes stack corruption.
See the following discussion explaining the issue https://sourceforge.net/p/exip/discussion/1177916/thread/c32cced9/#7575

When fixing this, check in other places for the same problem.

Start by reading the linked SourceForge bug and discussion, then inspect createUriTableEntry() and the addPfxEntry() call involving pfxEntryId. Check whether the pointer types match and look for other calls with the same mismatch. Done means the corruption risk is fixed throughout the affected uses or the issue is confirmed unnecessary with supporting evidence.
