Simplify three Ukraine zones to one, since the post-1970

misc/zoneinfo: Enable BACKWARDS by default

* Install the backwards-compatibility links by default
* Bump PORTREVISION

misc/zoneinfo: Update to 2022a

* Palestine will spring forward on 2022-03-27, not -03-26.
 * zdump -v now outputs better failure indications.
 * Bug fixes for code that reads corrupted TZif data.

misc/zoneinfo: Update to version 2021e

Changes to future timestamps
* Palestine will fall back 10-29 (not 10-30) at 01:00.
* Fiji will suspend observance of DST for the 2021/2022 season. (from 2021d)

misc/zoneinfo: Updated to 2021b

Briefly:
  Jordan now starts DST on February's last Thursday.
  Samoa no longer observes DST.
  Merge more location-based Zones whose timestamps agree since 1970.
  Move some backward-compatibility links to 'backward'.
  Rename Pacific/Enderbury to Pacific/Kanton.
  Correct many pre-1993 transitions in Malawi, Portugal, etc.

Remove # $FreeBSD$ from Makefiles.

Update to 2021a

Changes to future timestamps
    * South Sudan changes from +03 to +02 on 2021-02-01 at 00:00.

Update to 2020f

Change to the build procedure:

`make rearguard_tarballs` no longer generates a bad rearguard.zi, fixing a
2020e bug.

There are no changes to the data since 2020e.

Update to 2020e

Changes to future timestamps:

Volgograd switches to Moscow time on 2020-12-27 at 02:00.

Changes to past timestamps:

Correct many pre-1986 transitions, fixing entries originally
derived from Shanks.  The fixes include:
  - Australia: several 1917 through 1971 transitions
  - Bahamas: several 1941 through 1945 transitions
  - Bermuda: several 1917 through 1956 transitions
  - Belize: several 1942 through 1968 transitions
  - Ghana: several 1915 through 1956 transitions
  - Israel and Palestine: several 1940 through 1985 transitions
  - Kenya and adjacent: several 1908 through 1960 transitions
  - Nigeria and adjacent: correcting LMT in Lagos, and several 1905
    through 1919 transitions
  - Seychelles: the introduction of standard time in 1907, not 1906
  - Vanuatu: DST in 1973-1974, and a corrected 1984 transition

Because of the Australia change, Australia/Currie (King Island) is
no longer needed, as it is identical to Australia/Hobart for all
timestamps since 1970 and was therefore created by mistake.
Australia/Currie has been moved to the 'backward' file and its
corrected data moved to the 'backzone' file.

Changes to past time zone abbreviations and DST flags:

To better match legislation in Turks and Caicos, the 2015 shift to
year-round observance of -04 is now modeled as AST throughout before
returning to Eastern Time with US DST in 2018, rather than as
maintaining EDT until 2015-11-01.

Update to 2020d

Palestine ends DST earlier than predicted, on 2020-10-24.

Update to 2020b

Revised predictions for Morocco's changes starting in 2023.
Canada's Yukon changes to -07 on 2020-11-01, not 2020-03-08.
Macquarie Island has stayed in sync with Tasmania since 2011.
Casey, Antarctica is at +08 in winter and +11 in summer.
zic no longer supports -y, nor the TYPE field of Rules.

Update to 2020a

PR:		245892
Submitted by:	andrew@tao11.riddles.org.uk

Update to 2019c

Fiji observes DST from 2019-11-10 to 2020-01-12.
Norfolk Island starts observing Australian-style DST.

misc/zoneinfo: install zone1970.tab and other fixes

Install zone1970.tab in addition to zone.tab (like D20646 for base).

The old logic to remove countries from zone.tab doesn't port to
zone1970.tab since some lines might have to be patched more than
once. Replace it with some awk.

Remove LEAPFILE reference that wasn't being set anyway.

Fix plist entry for Etc/UCT, which is (since 2019a) part of
"backward" and not present otherwise.

Make BACKWARD not be the default, since (a) it's not the base system's
default and (b) that stuff is all deprecated.

Update comment about check-plist to include a reminder to check both with
and without BACKWARD (this would have caught the existing plist error).

Remove no-longer-needed include of bsd.port.pre.mk.

Fix location and name of iso3166 file in comments in zone1970.tab, also
to match base system.

Add back a test-pkgplist target, because it turns out check-plist is not
strict enough to handle the case of moving entries into or out of the
"backward" set; check-plist doesn't error if a file is present in STAGEDIR
but is commented out in the plist, but we want that to be noticed.

Changes to future time stamps

    Turkey switched from EET/EEST (+02/+03) to permanent +03,
    effective 2016-09-07.  (Thanks to Burak AYDIN.)  Use "+03" rather
    than an invented abbreviation for the new time.

    New leap second 2016-12-31 23:59:60 UTC as per IERS Bulletin C 52.
    (Thanks to Tim Parenti.)

  Changes to past time stamps

    For America/Los_Angeles, spring-forward transition times have been
    corrected from 02:00 to 02:01 in 1948, and from 02:00 to 01:00 in
    1950-1966.

    For zones using Soviet time on 1919-07-01, transitions to UT-based
    time were at 00:00 UT, not at 02:00 local time.  The affected
    zones are Europe/Kirov, Europe/Moscow, Europe/Samara, and
    Europe/Ulyanovsk.  (Thanks to Alexander Belopolsky.)

  Changes to past and future time zone abbreviations

    The Factory zone now uses the time zone abbreviation -00 instead
    of a long English-language string, as -00 is now the normal way to
    represent an undefined time zone.

    Several zones in Antarctica and the former Soviet Union, along
    with zones intended for ships at sea that cannot use POSIX TZ
    strings, now use numeric time zone abbreviations instead of
    invented or obsolete alphanumeric abbreviations.  The affected
    zones are Antarctica/Casey, Antarctica/Davis,
    Antarctica/DumontDUrville, Antarctica/Mawson, Antarctica/Rothera,
    Antarctica/Syowa, Antarctica/Troll, Antarctica/Vostok,
    Asia/Anadyr, Asia/Ashgabat, Asia/Baku, Asia/Bishkek, Asia/Chita,
