Completely re-vamped `tzsetup':
- It no longer attempts to fiddle wall-vs-UTC-in-RTC. The results were just confusing most of the time. - The program no longer contains a pre-compiled list of timezones (compiled by groveling through the tzdata source files for comments starting with `ZONE-DESCR'). Now it uses the new `zone.tab' file supplied with current versions of the timezone data files, to determine the list at run time. (It also requires the ISO 3166 table I committed some months ago.) AS A RESULT, this program will NOT work until the new timezone data files are committed (should happen sometime soon).
