[cp-patches] [calendar] fix Calendar.setTimeZone()

[Gary Benson]

Hi again,

This commit makes Calendar.setTimeZone() simply invalidate the
fields rather than recalculating the entire thing.  There seems
to be a general thing of setters invalidate, getters calculate
going on in Sun's implementation.  At the moment in Classpath
we have a bit of a mixture, which makes things... interesting :)

Cheers,
Gary
