	strerror, strsignal, and their variants should return unique strings for each known (and, depending on the function, unknown) error/signal. Add tests to verify this for strerror, strerror_r (GNU and XSI compliant variants), and strerror_l (for the C locale), strerrordesc_np, strsignal, sigabbrev_np, and sigdescr_np.
