time zone data: Update to 2016i

that is quoted with < >  (e.g. "<+03>-3")

Key changes in 2016d-2016i:
---------------------------

2016d:
     America/Caracas switches from -0430 to -04 on 2016-05-01.

     Asia/Magadan switches from +10 to +11 on 2016-04-24.

     New zone Asia/Tomsk, split off from Asia/Novosibirsk.

2016f:
     Asia/Novosibirsk switches from +06 to +07 on 2016-07-24.

     Asia/Novokuznetsk and Asia/Novosibirsk now use numeric time zone
     abbreviations instead of invented ones.

2016g:
     Turkey switched from EET/EEST (+02/+03) to permanent +03,
     effective 2016-09-07. Use "+03" rather than an invented
     abbreviation for the new time.

     Several zones in Antarctica and the former Soviet Union, along
     with zones intended for ships at sea that cannot use POSIX TZ
     strings, now use numeric time zone abbreviations instead of
     invented or obsolete alphanumeric abbreviations.

2016h:
     Asia/Gaza and Asia/Hebron end DST on 2016-10-29, not
     2016-10-21. Predict that future fall transitions will
     be on the last Saturday of October.

     Asia/Colombo now uses numeric time zone abbreviations like "+0530"
     instead of alphabetic ones like "IST" and "LKT".

2016i:
     Pacific/Tongatapu begins DST on 2016-11-06, ending on
     2017-01-15.  Assume future observances in Tonga will be
     from the first Sunday in November through the third Sunday in
     January, like Fiji. 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.

     Antarctica/Casey switched from +08 to +11 on 2016-10-22.
