Bug#16169063: SECURITY CONCERN BECAUSE OF INSUFFICIENT LOGGING

PROBLEM: If multiple statements are sent by a single
         request then only the last statement was
         getting logged. An attacker can bypass the
         audit log just by sending two comsecutive
         statements in one request.

SOLUTION: Each statements from a single request are
          logged.
