Bug 541600 – GtkCalendar segfault for certain values of detail-with-chars

* gtk/gtkcalendar.c (gtk_calendar_class_init()): Limit the "year"
  property to G_MAXINT >> 9, instead of G_MAXINT >> 8: year_to_days()
  multiplies the year property with 365 and returns the result as
  glong. Therefore ceil(log(365, 2)) = 9 bits must be available,
  not just 8 bits.
