Improve strncpy_s src/dst overlap check
Let m = user estimate of the (max) src string length, low = smaller address of (src, dst), hi = larger address (src, dst). if (low + (m - 1) >= hi), we have a *potential* overlapping copy which is not allowed. Before we declare overlap - and return an error - retry the check with m = actual src string length. The resulting "test string" failure affected aarch64 (only) because of differences in test code stack variable placement / alignment.
