QTimeZone::displayName() may return empty if it has no suitably-localized name for the zone. So QCalendarBackend's dateTimeToString() can't rely on its tzAbbr() returning a string that starts with UTC (and it may now, with proper L10n, start with some other prefix) or indeed has length >= 3 (so sliced(3) could crash). Rework the handling of offset name (mainly for the pick back to 6.8, as I'll be back to get rid of the kludging in 6.9) to at least not crash on empty return. In the process, use decreasingly appropriate forms as fallbacks if we don't get what we want.
