Replace some function calls with their non-deprecated equivalents so that we can remove _CRT_NONSTDC_NO_DEPRECATE from CMakeLists.txt and config.nmake. Leave _CRT_SECURE_NO_DEPRECATE in place. Removing it failed with 145 warnings and 72 errors. Note that we could probably improve startup performance by using wmem in diam_dict.*.
