Sync zoneinfo database with tzdata2014h from ftp://ftp.iana.org/tz/releases

We're coming from tzdata2014e.

Changes affecting future time stamps:

* Russia will subtract an hour from most of its time zones on 2014-10-26
    at 02:00 local time.  (Thanks to Alexander Krivenyshev.)

* Turks & Caicos is switching from US eastern time to UTC-4 year-round,
    modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00.

* Tons of changes to past time stamps and cleanup. It's really too much
    to repeat here. Please see the NEWS file for further information.
