WL#5825 Using C++ Standard Library with MySQL code

The goal of this worklog is to allow the use of the C++ Standard Library
inside the code and to enable exceptions and RTTI for the MyQL code
base. The goal is *not* to start using the the standard C++ library
throughout the code base, just to ensure that it is possible.
