Update time zone data files to tzdata release 2017b. 

DST law changes in Chile, Haiti, and Mongolia.  Historical corrections for
Ecuador, Kazakhstan, Liberia, and Spain.

The IANA crew continue their campaign to replace invented time zone
abbrevations with numeric GMT offsets.  This update changes numerous zones
in South America, the Pacific and Indian oceans, and some Asian and Middle
Eastern zones.  I kept these abbreviations in the tznames/ data files,
however, so that we will still accept them for input.  (We may want to
start trimming those files someday, but I think we should wait for the
upstream dust to settle before deciding what to do.)

In passing, add MESZ (Mitteleuropaeische Sommerzeit) to the tznames lists;
since we accept MEZ (Mitteleuropaeische Zeit) it seems rather strange not
to take the other one.  And fix some incorrect, or at least obsolete,
comments that certain abbreviations are not traceable to the IANA data.

# European-style abbreviations are commonly used along the Mediterranean.
# For sub-Saharan Africa abbreviations were less standardized.
# Previous editions of this database used WAT, CAT, SAT, and EAT
# for +0:00 through +3:00, respectively,
# but Mark R V Murray reports that
# 'SAST' is the official abbreviation for +2:00 in the country of South Africa,
# 'CAT' is commonly used for +2:00 in countries north of South Africa, and
# 'WAT' is probably the best name for +1:00, as the common phrase for
# for UT +00 through +03, respectively,
# but in 1997 Mark R V Murray reported that
# 'SAST' is the official abbreviation for +02 in the country of South Africa,
# 'CAT' is commonly used for +02 in countries north of South Africa, and
# 'WAT' is probably the best name for +01, as the common phrase for
# the area that includes Nigeria is "West Africa".
# He has heard of "Western Sahara Time" for +0:00 but can find no reference.
#
# To make things confusing, 'WAT' seems to have been used for -1:00 long ago;
# I'd guess that this was because people needed _some_ name for -1:00,
# and at the time, far west Africa was the only major land area in -1:00.
# This usage is now obsolete, as the last use of -1:00 on the African
# mainland seems to have been 1976 in Western Sahara.
#
# To summarize, the following abbreviations seem to have some currency:
# -1:00 WAT West Africa Time (no longer used)
# 0:00 GMT Greenwich Mean Time
# 2:00 CAT Central Africa Time
# 2:00 SAST South Africa Standard Time
# and Murray suggests the following abbreviation:
# 1:00 WAT West Africa Time
# I realize that this leads to 'WAT' being used for both -1:00 and 1:00
# for times before 1976, but this is the best I can think of
# until we get more information.
# To summarize, the following abbreviations seemed to have some currency:
# +00 GMT Greenwich Mean Time
# +02 CAT Central Africa Time
# +02 SAST South Africa Standard Time
# and Murray suggested the following abbreviation:
# +01 WAT West Africa Time
# Murray's suggestion seems to have caught on in news reports and the like.
# I vaguely recall 'WAT' also being used for -01 in the past but
# cannot now come up with solid citations.
#
# I invented the following abbreviations; corrections are welcome!
# 2:00 WAST West Africa Summer Time
# 2:30 BEAT British East Africa Time (no longer used)
# 2:45 BEAUT British East Africa Unified Time (no longer used)
# 3:00 CAST Central Africa Summer Time (no longer used)

# The other three time zones are called "Brasília time "minus one" or

# This says President Sixto Durán Ballén signed decree No. 285, which
# established DST from 1992-11-28 to 1993-02-05; it does not give transition
# times. The people called it "hora de Sixto" ("Sixto hour"). The change did
# not go over well; a popular song "Qué hora es" by Jaime Guevara had lyrics
# that included "Amanecía en mitad de la noche, los guaguas iban a clase sin
# sol" ("It was dawning in the middle of the night, the buses went to class
# without sun"). Although Ballén's campaign slogan was "Ni un paso atrás"
# (Not one step back), the clocks went back in 1993 and the experiment was not
# repeated. For now, assume transitions were at 00:00 local time country-wide.

The files named Africa.txt, etc, are not intended to be used directly as
time zone abbreviation files. They contain reference definitions of time zone
abbreviations that can be copied into a custom abbreviation file as needed.
Note that these files (*.txt) are already a subset of the IANA timezone
database files: we tried to list only those time zone abbreviations that
(according to the IANA timezone database) appear to be still in use.
These files contain most of the time zone abbreviations that were shown
in the IANA timezone database circa 2010.
However, it turns out that many of these abbreviations had simply been
invented by the IANA timezone group, and do not have currency in real-world
use. The IANA group have changed their policy about that, and now prefer to
use numeric UTC offsets whenever there's not an abbreviation with known
real-world popularity. A lot of these abbreviations therefore no longer
appear in the IANA data, and so are marked "obsolete" in these data files.
