Added WeakLink...Generator classes (should have done that ages ago). These check the c-function pointer for being NULL before calling it and raise UnimplementedError if it is. This allows system libs to be weak-linked, thereby allowing us to generate functions that are only available on some OS versions without getting a NULL dereference if the function isn't available.
