Revert recent pre-1970 changes.
Other tz file readers had problems with the new pre1970 file, so
remove it and related changes. To recover the pre-1970 data,
instead change pre-1970 Zone entries in other files back to what
they were. Perhaps we'll try to find a better way someday.
* .gitignore: Remove back-pre1970.
* Makefile (BACKWARD): Remove. All uses changed back to 'backward'.
(AWK_SCRIPTS): Remove back-pre1970.awk.
(back-pre1970): Remove.
(clean_misc): Don't rm back-pre1970.

Replace some zones with links when that doesn't lose non-LMT info.
* northamerica (America/Anguilla, America/Dominica, America/Grenada)
(America/Guadeloupe, America/Montserrat, America/St_Kitts)
(America/St_Lucia, America/St_Vincent, America/Tortola)
(America/St_Thomas):
Link to America/Port_of_Spain instead of having a separate zone
that differs only in LMT. Each LMT entry is just a placeholder for
unavailable info, and by itself does not justify a separate zone.
Using just one zone simplifies maintenance, makes the runtime
a bit smaller, and can help simplify user selection of zones.
* southamerica (America/Aruba): Likewise, for America/Curacao.
* backward (America/Virgin):
* northamerica (America/St_Barthelemy, America/Marigot):
Adjust to the other changes, by not linking to a link.

Move links to 'backward' if they exist only because of country codes.
* backward: Move links here from other files, if the only reason
they existed was to fill out zone.tab. Zones are now allowed to
cross national borders, so a zone now need not exist merely
because there's a national border. Sort the list consistently.
None of this changes any time stamp in the database.
