tzcode-native: update to 2017a

  Changes to code

    zic no longer mishandles some transitions in January 2038 when it
    attempts to work around Qt bug 53071.  This fixes a bug affecting
    Pacific/Tongatapu that was introduced in zic 2016e. localtime.c
    now contains a workaround, useful when loading a file generated by
    a buggy zic.  (Problem and localtime.c fix reported by Bradley
    White.)

    zdump -i now outputs non-hour numeric time zone abbreviations
    without a colon, e.g., "+0530" rather than "+05:30".  This agrees
    with zic %z and with common practice, and simplifies auditing of
    zdump output.

    zdump is now buildable again with -DUSE_LTZ=0.
    (Problem reported by Joseph Myers.)

    zdump.c now always includes private.h, to avoid code duplication
    with private.h.  (Problem reported by Kees Dekker.)

    localtime.c no longer mishandles early or late timestamps
    when TZ is set to a POSIX-style string that specifies DST.
    (Problem reported by Kees Dekker.)

    date and strftime now cause %z to generate "-0000" instead of
    "+0000" when the UT offset is zero and the time zone abbreviation
    begins with "-".

  Changes to documentation and commentary

    The 'Theory' file now better documents choice of historical time
    zone abbreviations.  (Problems reported by Michael Deckers.)

    tz-link.htm now covers leap smearing, which is popular in clouds.
