Calendar.java (set): Never recompute fields here.

Browse source 
* java/util/Calendar.java (set): Never recompute fields here. They
	will already be set if someone set time explicitly, and it can cause
	problems to do so. Don't invalidate AM_PM setting if HOUR is set.
	* java/util/GregorianCalendar.java (computeTime): Don't ignore an
	HOUR setting if AM_PM is set. Don't try to ensure the HOUR value is
	sane.
	* java/text/SimpleDateFormat.java (defaultCentury): New field.
	(readObject): Call set2DigitYearStart if appropriate so that
	defaultCentury is calculated.
	(SimpleDateFormat): Don't bother clearing calendar here. Call
	computeCenturyStart().
	(set2DigitYearStart): Calculate and set defaultCentury.
	(format): Don't clone the calendar. Use "calendar" not "theCalendar"
	everywhere.
	(parse): Likewise. If the pattern is "y" or "yy" and it found exactly
	2 numeric digits, use the 80-20 heuristic to parse the value into a
	default century based on defaultCenturyStart.
	(computeCenturyStart): Rewritten. Call set2DigitYearStart().
