Add a best effort test to check shared library consistency

Our main development platforms are of the Unix family, which doesn't

as Windows is with the contents of the .def file or VMS is with the

To eliminate surprises, we therefore need to make sure to check that
the contents of the .map file is matched with the shared library, at
least to check that the shared library isn't missing any symbols that

This test isn't absolutely perfect, as it will only check the symbols
that would be present on Linux / Solaris and will therefore miss those
that would only appear on Windows or VMS.  On the other hand, those
