Title: ENG-3633

Improve constraint violation error logging in the easiest possible way.
ConstraintFailureException already has all the info we
care about; override message() to generate a useful string.
Also:
- Address namespace pet peeve
- Add CONSTRAINT_TYPE_PARTITIONING to constraintutil::getNameForType()
- Make construction of ConstraintFailureException() use
consistent calling convention for new/previous tuple argument order.
