datetime: clean-ups and new API adjustments
Remove constructors we don't want: gst_date_time_new_ymd_h() because we don't want to support hour-only for now; gst_date_time_new_ymd_hm() because we don't want to add constructors with time info where the caller doesn't have to think about what timezone the time is in. Lots of compulsive clean-up. Docs fixes. Replace has_minute() and has_hour() with has_time().
