Since massageAdjustedDateTime() has to split LocalTime from TimeZone
and call {local,zone}MSecsToEpochMSecs() in any case, its call to
refreshZonedDateTime(), via checkValidDateTime(), was duplicating that
work uselessly. So handle UTC and offset-from-UTC separately with a
call to refreshSimple and handle local/zone time by inlining what
remains of refreshZonedDateTime() aside from the duplication.
At the same time, recent reworking of qt_mktime() make
localMSecsToEpochMSecs() handle its DST-hint the same way
zoneMSecsToEpochMSecs() has long done so, to take care of the intended
handling of DST gaps and repeats.
