Paul Eggert 5ddc47fe41 New file time.tab, superseding zone.tab ...

It allows multiple country codes per zone.  Switch code and data to
use the new format, along with the recently-added Crozet Islands entry.
The old zone.tab file is still installed but is deprecated.
The new file uses UTF-8; add commentary saying that iso3166.tab is
planned to change to UTF-8.
