Update time zone data files to tzdata release 2014h.

Most zones in the Russian Federation are subtracting one or two hours
as of 2014-10-26.  Update the meanings of the abbreviations IRKT, KRAT,
MAGT, MSK, NOVT, OMST, SAKT, VLAT, YAKT, YEKT to match.

The IANA timezone database has adopted abbreviations of the form AxST/AxDT
for all Australian time zones, reflecting what they believe to be current
majority practice Down Under.  These names do not conflict with usage
elsewhere (other than ACST for Acre Summer Time, which has been in disuse
since 1994).  Accordingly, adopt these names into our "Default" timezone
abbreviation set.  The "Australia" abbreviation set now contains only
CST,EAST,EST,SAST,SAT,WST, all of which are thought to be mostly historical
usage.  Note that SAST has also been changed to be South Africa Standard
Time in the "Default" abbreviation set.

Add zone abbreviations SRET (Asia/Srednekolymsk) and XJT (Asia/Urumqi),
and use WSST/WSDT for western Samoa.

Also a DST law change in the Turks & Caicos Islands (America/Grand_Turk),
and numerous corrections for historical time zone data.

-# This file contains a table where each row stands for an area that is
