Julian days < 347998 denote invalid Jewish calendar dates, so cal_from_jd($jd, CAL_JEWISH) and jdmonthname($jd, CAL_MONTH_JEWISH) should actually fail. For BC we don't yet let them though, but we fix the OOB read that happens in this case, and we also adjust cal_from_jd()'s return value to have empty strings for "abbrevdayname" and "dayname" instead of "Sun"/ "Sunday" and NULL for "dow" instead of 0, which doesn't make any sense.
