tnurnberg@mysql.com d1311e1ac7 Bug#18997: DATE_ADD and DATE_SUB perform year2K autoconversion magic on 4-digit year value ...

if input year for date_add() / date_sub() with INTERVAL is low enough for
calc_daynr() to possibly return incorrect results (calc_daynr() has no information
on whether the year is low because it was a two-digit year ('77) or because it
was a really low four-digit year (0077) and will indiscriminately try to turn the
value into a four-digit year by adding 1900 or 2000 respectively), the functions
will now throw NULL.
