QDateTime - Add api for Time Zone Abbreviation

Add a new method to return the time zone abbreviation for the current
time spec.  For LocalTime this is the abbreviation returned by mktime.

This new method will later be used in changes to the date formatter
and QTimeZone.

Note this change does not implement WinCE support.

return effective time zone abbreviation.
