  Changes to code

    Fix bug when mktime gets confused by truncated TZif files with
    unspecified local time.  (Problem reported by Almaz Mingaleev.)

    Fix bug when 32-bit time_t code reads malformed 64-bit TZif data.
    (Problem reported by Christos Zoulas.)

    When reading a version 2 or later TZif file, the TZif reader now
    validates the version 1 header and data block only enough to skip
    over them, as recommended by RFC 8536 section 4.  Also, the TZif
    reader no longer mistakenly attempts to parse a version 1 TZIf
    file header as a TZ string.

    zdump -v now outputs "(localtime failed)" and "(gmtime failed)"
    when local time and UT cannot be determined for a timestamp.
