Patch: Another SimpleDateFormat.parse fix

[Tom Tromey]

I'm checking this in on the trunk.

Jeff and Bryce have convinced me that the calendar fixes are important
enough for the branch.  If I find the time I will migrate them over.
If someone else wants to do it, fine...

This patch fixes another bug in SimpleDateFormat.parse().  This bug
occurs when parsing a time to which daylight savings applies but where
the time zone is not specified.  I added a Mauve test for this.

I already checked this in to Classpath.

	* java/text/SimpleDateFormat.java (parse): Clear DST_OFFSET and
	ZONE_OFFSET just before computing the time.
