timezone: update to 2019a

The 2019a release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes:

  Briefly:
    Palestine "springs forward" on 2019-03-30 instead of 2019-03-23.
    Metlakatla "fell back" to rejoin Alaska Time on 2019-01-20 at 02:00.

  Changes to past and future timestamps

    Palestine will not start DST until 2019-03-30, instead of 2019-03-23 as
    previously predicted.  Adjust our prediction by guessing that spring
    transitions will be between 24 and 30 March, which matches recent practice
    since 2016.  (Thanks to Even Scharning and Tim Parenti.)

    Metlakatla ended its observance of Pacific standard time,
    rejoining Alaska Time, on 2019-01-20 at 02:00.  (Thanks to Ryan
    Stanley and Tim Parenti.)

  Changes to past timestamps

    Israel observed DST in 1980 (08-02/09-13) and 1984 (05-05/08-25).
    (Thanks to Alois Treindl and Isaac Starkman.)

  Changes to time zone abbreviations

    Etc/UCT is now a backward-compatibility link to Etc/UTC, instead
    of being a separate zone that generates the abbreviation "UCT",
    which nowadays is typically a typo.  (Problem reported by Isiah
    Meadows.)

  Changes to code

    zic now has an -r option to limit the time range of output data.
    For example, 'zic -r @1000000000' limits the output data to
    timestamps starting 1000000000 seconds after the Epoch.
    This helps shrink output size and can be useful for applications
    not needing the full timestamp history, such as TZDIST truncation;
    see Internet RFC 8536 section 5.1.  (Inspired by a feature request
    from Christopher Wong, helped along by bug reports from Wong and
    from Tim Parenti.)

  Changes to documentation

    Mention Internet RFC 8536 (February 2019), which documents TZif.

    tz-link.html now cites tzdata-meta
    <https://tzdata-meta.timtimeonline.com/>.
