Update time zone data files to tzdata release 2016g.

DST law changes in Turkey.  Historical corrections for America/Los_Angeles,
Europe/Kirov, Europe/Moscow, Europe/Samara, and Europe/Ulyanovsk.
Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link.

The IANA crew continue their campaign to replace invented time zone
abbrevations with numeric GMT offsets.  This update changes numerous zones
in Antarctica and the former Soviet Union, for instance Antarctica/Casey
now reports "+08" not "AWST" in the pg_timezone_names view.  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 today is not that day.)

An exception is that since IANA no longer claims that "AMT" is in use
in Armenia for GMT+4, I replaced it in the Default file with GMT-4,
corresponding to Amazon Time which is in use in South America.  It may be
that that meaning is also invented and IANA will drop it in a future
update; but for now, it seems silly to give pride of place to a meaning
not traceable to IANA over one that is.

+# From Paul Eggert (2016-08-20):
+# In early February 1948, in response to California's electricity shortage,
+# PG&E changed power frequency from 60 to 59.5 Hz during daylight hours,
+# causing electric clocks to lose six minutes per day.  (This did not change
+# legal time, and is not part of the data here.)  See:
+# Ross SA. An energy crisis from the past: Northern California in 1948.
+# Working Paper No. 8, Institute of Governmental Studies, UC Berkeley,
+# 1973-11.  http://escholarship.org/uc/item/8x22k30c
+#
+# In another measure to save electricity, DST was instituted from 1948-03-14
+# at 02:01 to 1949-01-16 at 02:00, with the governor having the option to move
+# the fallback transition earlier.  See pages 3-4 of:
+# http://clerk.assembly.ca.gov/sites/clerk.assembly.ca.gov/files/archive/Statutes/1948/48Vol1_Chapters.pdf
+#
+# In response:
+#
+#   Governor Warren received a torrent of objecting mail, and it is not too much
+#   to speculate that the objections to Daylight Saving Time were one important
+#   factor in the defeat of the Dewey-Warren Presidential ticket in California.
+#     -- Ross, p 25
+#
+# On December 8 the governor exercised the option, setting the date to January 1
+# (LA Times 1948-12-09).  The transition time was 02:00 (LA Times 1949-01-01).
+#
+# Despite the controversy, in 1949 California voters approved Proposition 12,
+# which established DST from April's last Sunday at 01:00 until September's
+# last Sunday at 02:00. This was amended by 1962's Proposition 6, which changed
+# the fall-back date to October's last Sunday. See:
