Update timezone data to 2016b

Update timezone data to 2016b

  Changes affecting future time stamps

    New zones Europe/Astrakhan and Europe/Ulyanovsk for Astrakhan and
    Ulyanovsk Oblasts, Russia, both of which will switch from +03 to +04 on
    2016-03-27 at 02:00 local time.  They need distinct zones since their
    post-1970 histories disagree.  New zone Asia/Barnaul for Altai Krai and
    Altai Republic, Russia, which will switch from +06 to +07 on the same date
    and local time.  Also, Asia/Sakhalin moves from +10 to +11 on 2016-03-27
    at 02:00.  (Thanks to Alexander Krivenyshev for the heads-up, and to
    Matt Johnson and Stepan Golosunov for followup.)

    As a trial of a new system that needs less information to be made up,
    the new zones use numeric time zone abbreviations like "+04"
    instead of invented abbreviations like "ASTT".

    Haiti will not observe DST in 2016.  (Thanks to Jean Antoine via
    Steffen Thorsen.)

    Palestine's spring-forward transition on 2016-03-26 is at 01:00, not 00:00.
    (Thanks to Hannah Kreitem.) Guess future transitions will be March's last
    Saturday at 01:00, not March's last Friday at 24:00.

  Changes affecting past time stamps

    Europe/Chisinau observed DST during 1990, and switched from +04 to
    +03 at 1990-05-06 02:00, instead of switching from +03 to +02.
    (Thanks to Stepan Golosunov.)

    1991 abbreviations in Europe/Samara should be SAMT/SAMST, not
    KUYT/KUYST.  (Thanks to Stepan Golosunov.)

The update produced (apparently benign) warnings from zic as suggested here:
