[tz] [PATCH 2/4] Move obsolescent Americas entries to 'backward'.

Mon Aug 26 17:16:24 UTC 2013
This continues in the series of moving entries to 'backward' if
they exist only because of obsolete tz rules about country codes.
In this case, Zone entries are changed to Links; this doesn't
affect any post-1970 time stamps, and the pre-1970 time stamps
are out of scope and are often of dubious reliability.
* backward, northamerica, southamerica (America/Anguilla)
(America/Antigua, America/Aruba, America/Blanc-Sablon)
(America/Cayman, America/Curacao, America/Dominica)
(America/Grenada, America/Guadeloupe, America/Montserrat)
(America/Port_of_Spain, America/St_Kitts, America/St_Lucia)
(America/St_Thomas, America/St_Vincent, America/Tortola):
Now 'backward' links to America/Puerto_Rico.
(America/Atikokan): Now a 'backward' link to America/Panama.
(America/Creston): Now a 'backward' link to America/Phoenix.
(America/Nassau): Now a 'backward' link to America/Toronto.
* backward (America/Coral_Harbour, America/Kralendijk)
(America/Lower_Princes, America/Marigot, America/St_Barthelemy)
(America/Virgin): Adjust to avoid link-to-a-link.
