      Update IANA timezone database to 2018i · d6530149
      Jungshik Shin authored 
      2018h and 2018i were announced in a quick succession in the last week
of 2018.

Timezones in a part of Kazakhstan (Asia/Qyzylorda changed its offset and
new timezone Asia/Qostanay was added), a part of Alaska, São Tomé and
Príncipe changed at the end of 2018 or at the beginning of 2019. They
require this update now.

Either in JS console in Chrome or v8 should work like these:
d8> new Date(Date.UTC(2018,11,20,12)).toLocaleString("en", {timeZone: "Asia/Qyzylorda"})
"12/20/2018, 6:00:00 PM"
d8> new Date(Date.UTC(2018,11,21,12)).toLocaleString("en", {timeZone: "Asia/Qyzylorda"})
"12/21/2018, 5:00:00 PM"
d8> new Date(Date.UTC(2018,11,20,12)).toLocaleString("en", {timeZone: "Asia/Qostanay"})
"12/20/2018, 6:00:00 PM"
d8> new Date(Date.UTC(2018,11,21,12)).toLocaleString("en", {timeZone: "Asia/Qostanay"})
"12/21/2018, 6:00:00 PM"
d8> new Date(Date.UTC(2018,11,31,12)).toLocaleString("en", {timeZone: "Africa/Sao_Tome"})
"12/31/2018, 1:00:00 PM"
d8> new Date(Date.UTC(2019,0,1,12)).toLocaleString("en", {timeZone: "Africa/Sao_Tome"})
"1/1/2019, 12:00:00 PM"

Future expected changes in Iran and Moroco are also included in this update.

      Update IANA timezone db to 2018g · 407b3930
      Jungshik Shin authored 
      According to the announcement at
  https://mm.icann.org/pipermail/tz-announce/2018-October/000052.html ,

Morocco switches from +00/+01 to permanent +01 effective 2018-10-27,
so its clocks will not fall back on 2018-10-28 as previously
scheduled.

The tz-related files are updated by running update_tz.sh and ICU
data files are rebuilt.

In 2017, on the last Sunday of October, there was fall backward.
d8> new Date(Date.UTC(2017, 9, 28,12)).toLocaleString("en", {timeZone: "Africa/Casablanca"})
"10/28/2017, 1:00:00 PM"

In 2018, there is no transition on the last Sunday of October.

      Add more locale variants · 797b7c73
      Jungshik Shin authored 
      Make the locale variant support more uniform across locale
categories. What's supported in the main locale categories (data/locales)
are added to data/{unit,curr} as well. The list of locales in data/zone
is not yet updated.

Moreover, sr and sw variants are added to data/{locales,unit,curr}.

The cast removal list is simplified using 'glob' pattern instead of
listing individual files for curr and unit categories.

The data size is still under control on most platforms. They're actually
smaller than the first ICU 63.1 update thanks to additional trimming in
zone/unit categories except on desktop (59kB increase).

      Adjust calendar locale data trimming on Andorid · ecae5c0e
      Jungshik Shin authored 
      On Android, add Islamic calendar to Arabic and Farsi locales
and Indian calendar to Hindi locale. Also add both variants
of Ethiopic calendars to am/root.

There was a 'typo' in the locale trimming script for Android
('arabic' instead of 'islamic' was specified.). As a result,
Date formatting in ar-SA (where the default calendar is
Islamic) failed for the lack of locale data.

Add back calendar entries to data/locales/root.txt. They're
necessary to support locale-specific calendars on Android
(e.g. islamic on ar/fa, japanese on ja, hebrew on he, etc).

Adjust the drop list for the data file for cast. More
locale variants have been added since it's made. Drop
locale bundles for newly added variants.

Drop zone/unit data for 8 locales Android Chrome does not
yet support. This saves over 100 kB.

For all platforms, drop a few more items not yet used in
Chromium/v8.

With this change, the net data size decreased on all platforms,
paving the way to add more locale variants in a subsequent CL.

      Fix ICU data file for Android · a191af9d
      Jungshik Shin authored 
      In some locales, currency data turns empty after currency list filtering
on Android. This leads v8's currency formatter to fall back to 3-letter
currency code instead of currency symbol (e.g. 'GBP' in en-GB).

Fix the ICU data trimming script to remove an empty Currency block after
filtering and rebuild ICU data files.
