Update to latest tzdata / switch back to zones.tab
The file has fallen out of date since it was fundamentally
updated in commit 50e9b86. This change brings it up to date
with 2017b.
This change also switches back to using zone.tab as a source
of time zone IDs. In commit 50e9b86 the source was switched
to zone1970.tab. Although this switch wouldn't have
meaningfully affected time zone calculations it does alter
the exemplar locations for automatically detected time zones.
This information may surfaced to users in some places and
can lead to confusion because zone1970.tab uses zones that
span multiple countries, while zone.tab zones tend to be
more local. Reverting should lead to a subtly better
localization experience.
During this work a number of unexpected differences between
zone.tab and zone1970.tab were uncovered. These have been
questioned upstream via the IANA mailing list on 31st March
2017.
Notable other updates:
Addition of Asia/Famagusta for Cyprus.
Addition of Asia/Atyrau for Kazakhstan.
Addition of Europe/Saratov for Russia.
The following have been queried with IANA and differ between
zone.tab and zone1970.tab:
Removal of Indian/Reunion for French Southern Territories
Removal of Pacific/Honolulu for United States Minor Outlying Islands
Removal of Asia/Bangkok for Vietnam.
