Backport !1115 “gdatetime: Fix error handling in g_date_time_new_ordinal()” to glib-2-62
It was possible to pass in (for example) an invalid hour to
g_date_time_new_ordinal(), which would be passed on to
g_date_time_new(), which would (correctly) return
NULL — but then
g_date_time_new_ordinal() would try to dereference that.
Includes some test cases.
