Rebase to tzdata-2017a:

on 2017-01-15 at 03:00.

split in Cyprus time zones starting 2016-10-30 at 04:00 and
creates a new zone - Asia/Famagusta.
- Antarctica/Casey changed from +08 to +11 on 2016-10-22.
- Rebase to 2016g
- Turkey permanently switches from +02 to +03 as of 2016-09-07,

Ulyanovsk Oblasts, Russia, both of which will switch from +03 to +04 on
2016-03-27 at 02:00 local time. They need distinct zones since their
post-1970 histories disagree. New zone Asia/Barnaul for Altai Krai and
Altai Republic, Russia, which will switch from +06 to +07 on the same date
and local time. The Astrakhan change is already official; the others have
passed the first reading in the State Duma and are extremely likely.
Also, Asia/Sakhalin moves from +10 to +11 on 2016-03-27 at 02:00.
- As a trial of a new system that needs less information to be made up,
the new zones use numeric time zone abbreviations like "+04"
