Sync zoneinfo database with tzdata2016i from ftp://ftp.iana.org/tz/releases

* Pacific/Tongatapu begins DST on 2016-11-06 at 02:00, ending on
    2017-01-15 at 03:00.  Assume future observances in Tonga will be
    from the first Sunday in November through the third Sunday in
    January, like Fiji.  (Thanks to Pulu ʻAnau.)  Switch to numeric
    time zone abbreviations for this zone.

* Northern Cyprus is now +03 year round, causing a split in Cyprus
    time zones starting 2016-10-30 at 04:00.  This creates a zone
    Asia/Famagusta.  (Thanks to Even Scharning and Matt Johnson.)

* Antarctica/Casey switched from +08 to +11 on 2016-10-22.
    (Thanks to Steffen Thorsen.)

* Several corrections were made for pre-1975 time stamps in Italy.
    These affect Europe/Malta, Europe/Rome, Europe/San_Marino, and
    Europe/Vatican.

  First, the 1893-11-01 00:00 transition in Italy used the new UT
    offset (+01), not the old (+00:49:56).  (Thanks to Michael
    Deckers.)

  Second, rules for daylight saving in Italy were changed to agree
    with Italy's National Institute of Metrological Research (INRiM)
    except for 1944, as follows (thanks to Pierpaolo Bernardi, Brian
    Inglis, and Michael Deckers):

    The 1916-06-03 transition was at 24:00, not 00:00.

    The 1916-10-01, 1919-10-05, and 1920-09-19 transitions were at
      00:00, not 01:00.

    The 1917-09-30 and 1918-10-06 transitions were at 24:00, not
      01:00.

    The 1944-09-17 transition was at 03:00, not 01:00.  This
      particular change is taken from Italian law as INRiM's table,
      (which says 02:00) appears to have a typo here.  Also, keep the
      1944-04-03 transition for Europe/Rome, as Rome was controlled by
      Germany then.

    The 1967-1970 and 1972-1974 fallback transitions were at 01:00,
      not 00:00.
