Import tzdata2018f from ftp://ftp.iana.org/tz/releases/tzdata2018f.tar.gz

  Volgograd moves from +03 to +04 on 2018-10-28.
  Fiji ends DST 2019-01-13, not 2019-01-20.
  Most of Chile changes DST dates, effective 2019-04-06.

  Plus corrections to North Korea's 2018-05-05 and China's April 1988
  updates (getting the actual time/date of the transition correct)
  Corrections for Macau pre 1992, Japan in late 1940's - early 1950's,
  and China (Shanghai) 1940's.  The Phillipines get their timezone
  name abbreviations back.
