Howard Hinnant a610f087c1 Add support for the zic-compiled OS-supplied time zone DB: ...

*  Avoids the need to download the IANA database.

*  Heavily based on contributions by Aaron Bishop.

*  Turn on with -DUSE_OS_TZDB, off by default.

*  Not supported on Windows.

*  Disables HAS_REMOTE_API.

*  get_tzdb().version only supported on Apple.  This string has
   the value "unknown" elsewhere.

*  Leap second support is missing on Apple, and may not be on your
   platform either (please report).  Leap second support is enabled,
   disabled with -DMISSING_LEAP_SECONDS.

   Without leap second support, utc_time, tai_time, and gps_time (and
   those clocks) are not available.

*  On Apple, time zone transitions are only supported in the range:

   1901-12-13 20:45:52 to 2038-01-19 03:14:07

*  On Linux, time zone transitions are only as far in the future as
   the OS-provided transitions go.  There is no support for POSIX-
   style transitions.
