Further fixes for the proposed Russian change on 2014-10-26.

* europe: Fix an 80-column issue in commentary.
(Asia/Novokuznetsk): Switch abbreviation from NOVT to KRAT on 2014-10-26
at 02:00.
(Asia/Krasnoyarsk, Asia/Khandyga, Asia/Sakhalin, Asia/Ust-Nera):
Subtract an hour on 2014-10-26 at 02:00.
(Asia/Magadan): Subtract two hours at that time.
* zone.tab (Europe/Samara, Asia/Novokuznetsk, Asia/Magadan, Asia/Kamchatka)
(Asia/Anadyr): Update descriptions relative to Moscow time.
* NEWS: Document this.
Prefer MSK/MSD for Volgograd when on Moscow time.

* europe: (Europe/Volgograd): Prefer MSK/MSD for Moscow time.
* NEWS: Document preference for MSK/MSD and EET/EEST.
Standardize commentary on the coverage of each Russian zone.

This borrows heavily from Oscar van Vlijmen's earlier work here.
Mention recent mergers of regions as well.
* europe (Europe/Volgograd): Reattribute old comment to Paul Eggert.
(Asia/Yakutsk): Confirm that Zabaykalsky Krai will need its own zone
from 2014-10-26.
(Asia/Vladivostok): Mention that Bulunsky District will need its own
zone to correctly record its history.
(Asia/Magadan): Mention that the parts of Sakha (Yakutia) Republic and
the North Kuril Islands covered by this zone will need their own zone
from 2014-10-26.
* NEWS: Document this.
Zone splits for the proposed Russian change on 2014-10-26

Also, a historical split.
* europe: Add commentary describing proposed future zones Asia/Chita and
Asia/Srednekolymsk, as well as proposed historical split Asia/Tiksi.
* NEWS: Document this.
Update zone.tab for Russia, and remove Asia/Tiksi comment.

My best guess is that the Asia/Tiksi entry is a false alarm,
and that the area hasn't diverged from Yakutsk since 1970.
* europe: Move zone.tab comments to zone.tab.
(Asia/Yakutsk): Move comment for Bulunsky district here,
Remove a comment about a draft Asia/Tiksi zone, containing the
Bulunsky district.  We don't have sufficient evidence that it
ever diverged from Yakutsk after 1970.
* zone.tab (RU): Reorder entries to make more geographical sense.
Add comments for draft zones Asia/Chita, Asia/Srednekolymsk.
(Europe/Samara, Asia/Novokuznetsk, Asia/Magadan, Asia/Kamchatka)

* NEWS: Document the above.
Pacify 'make check_character_set'.
* australasia (Pacific/Apia, WS): Move DST data from Zone to Rule lines.

This doesn't change the output, but is shorter and easier to follow.
Trim and adjust commentary a bit.
New link Indian/Alfred_Faure for the Crozet and Scattered Islands.

(Thanks to Tobias Conradi and Antoine Leca.)
* africa, zone.tab (Indian/Alfred_Faure): New link.
* antarctica: Adjust commentary accordingly.
* NEWS: Document this.

* europe: (Europe/Samara): Prefer MSK/MSD for Moscow time and EET/EEST for
Eastern European time.
(Asia/Srednekolymsk): Fix incorrect link in commentary.
* zone.tab (Asia/Chita): Mention that the Moscow offset changes 2014-10-26.

(Thanks to Arthur David Olson.)
Correct time in Russia before 1927 or so.

(Thanks to Vladimir Karpinsky for the Moscow corrections.)
Other corrections are taken from Milne 1899.

* zone.tab (Europe/Moscow): Use Kilometer 0 point.
* NEWS: Document this.
* europe: Fix date typos in recently-added commentary.
Replace some zones with links when that doesn't lose useful info.

This is like the 2013-09-02 change, but for the Pacific this time.
* antarctica (Antarctica/DumontDUrville):
* australasia (Pacific/Tahiti, Pacific/Saipan, Pacific/Majuro)
(Pacific/Chuuk, Pacific/Pohnpei, Pacific/Palau, Pacific/Funafuti)
(Pacific/Midway, Pacific/Wake, Pacific/Wallis):
Remove zone, replacing each with a link to a region that has had
the same UTC offset since 1970.  This removes data that were
largely invented, either by us or almost surely by Shanks or his
sources.
* asia, australasia, northamerica: Create links accordingly.
* NEWS: Document this.
Replace Africa zones with links when that doesn't lose useful info.

* africa (Africa/Luanda, Africa/Porto-Novo, Africa/Gaborone)

(Indian/Comoro, Africa/Kinshasa, Africa/Lubumbashi, Africa/Brazzaville)

(Africa/Freetown, Africa/Mogadishu, Africa/Mbabane, Africa/Dar_es_Salaam)
(Africa/Lome, Africa/Kampala, Africa/Lusaka, Africa/Harare):
* antarctica (Antarctica/Syowa):
Remove zone, replacing each with a link to a region that has had
the same UTC offset since 1970.
* NEWS: Document this.
No leap second on 2014-12-31.

* leap-seconds.list: Per IERS Bulletin C48 (2014-07-07), no leap second on
2014-12-31.  Update file from NIST.
Revert some zone-to-link changes and add some more; plus related fixes.

Revert zone-to-link changes that changed current time zone
abbreviations.  Add a few more changes, for more consistency.
Make several other fixes discovered while researching this.
* africa (Africa/Accra, Antarctica/Syowa):
* asia (Pacific/Palau):
* australasia (Pacific/Funafuti, Pacific/Majuro, Pacific/Wake)
(Pacific/Wallis, Antarctica/DumontDUrville, Pacific/Chuuk)
(Pacific/Pohnpei):
* northamerica (Pacific/Tahiti):
Remove links, as they are now zones again.
* africa (Africa/Accra, Africa/Maputo):
* antarctica (Antarctica/DumontDUrville, Antarctica/Syowa):
* australasia (Pacific/Tahiti, Pacific/Majuro, Pacific/Chuuk)
(Pacific/Pohnpei, Pacific/Palau, Pacific/Funafuti, Pacific/Wake)
(Pacific/Wallis):
Restore zone.
* africa (Africa/Accra): Assume DST starting in 1920, as per Scott
Keltie & Epstein 1920.
* asia (Asia/Bahrain, Asia/Phnom_Penh, Asia/Kuwait, Asia/Vientiane)
(Asia/Muscat, Asia/Ho_Chi_Minh, Asia/Aden):
* northamerica (America/Antigua, America/Cayman):
Change from zone to link, as these are also closely related.
* africa (Africa/Blantyre, Africa/Bujumbura, Africa/Gaborone)
(Africa/Harare, Africa/Kigali, Africa/Lubumbashi, Africa/Lusaka):
Now links to Africa/Maputo, not Africa/Johannesburg.
* asia (Asia/Riyadh): Change standard-time transition from 1950
to 1947-03-14.  Add commentary citing Hunt 1961 and CAB 1946.
* australasia (Pacific/Chatham): Assume NZST - 45 min. before 1946.
Add commentary about this.
(Pacific/Pago_Pago): UT-11 from 1911 to 1950.
(WS, Pacific/Apia): Use NZ-style abbreviations.
Switch to "WSST" for Western Samoa standard time before 1950.
Add commentary about Samoa before 1950.
* backward (Africa/Asmera, Africa/Timbuktu, Asia/Saigon):
Redo to avoid link-to-link.
* europe (Hungary, Europe/Bucharest): Several pre-1946
corrections: in 1918 the transition out of DST was on 09-16, not
09-29; in 1919 it was on 11-24, not 09-15; in 1945 it was on
11-01, not 11-03; in 1941 the transition to DST was 04-08 not
04-06 at 02:00; and there was no DST in 1920.

* southamerica: Add link for America/Antigua.
* NEWS: Document the above.  Add some thanks.
* tz-link.htm, NEWS: Mention the latlong package.

(Thanks to a heads-up from Dirkjan Ochtman.)
Be a bit more consistent about Metlakatla and Resolute abbr and comments.

* northamerica (America/Metlakatla): Use the more-common "PST"
rather than our invented "MeST" for the abbreviation.  Our source
called it "Pacific Time", as did a contemporaneous news report,
and I couldn't find contemporaneous use of "MeST" or of
"Metlakatla Time".  Cite the news report in the commentary,
and quote some Juneau graffiti.
* zone.tab (America/Resolute): Call it Central Time, not Central
Standard Time, since it observes DST now.
(America/Metlakatla): Call it Pacific Standard Time, not
Metlakatla Time.  Mention that it's in Alaska.
* NEWS: Document the above.
* zone.tab: Reorder to put Pacific times together.
New file time.tab, superseding zone.tab

It allows multiple country codes per zone.  Switch code and data to
use the new format, along with the recently-added Crozet Islands entry.
The old zone.tab file is still installed but is deprecated.
The new file uses UTF-8; add commentary saying that iso3166.tab is
planned to change to UTF-8.
* Theory, tzselect.8 (FILES): zone.tab -> time.tab.

* iso3166.tab: Mention planned switch to UTF-8.
Update ISO 3166-1 Newsletter from VI-15 to VI-16.
* time.tab: New file.
* tzselect.ksh (zonetabtype): New variable.
Add undocumented -t option, meant for developer testing.
(TZ_ZONE_TABLE): Use zonetabtype.

(quoted_continents, distance_table, countries, regions)
(TZ, TZ_for_date): Quote shell strings more carefully.
* zone.tab: Refer to time.tab for detailed comments about format.
(Indian/Alfred_Faure): Remove.
* Makefile (TIMETABLES): New macro.

* NEWS: Document the above.
