Tweak the package to better match the current file structure in the
upstream time zone database. Add missing aliases. Make some clarifications
* Combine -northmerica and -southamerica into -america, as all
current official America/xxx definitions were already in -northamerica
and only the unofficial/deprecated Brazil/xxx, Chile and Argentina were
in -southamerica. (Confusingly America/Sao_Paulo was in northamerica,
while Brazil was in southamerica.)
* Add PROVIDES for the old package names
* Add missing top-level dir country/nation alias links.
* Define Eire in -europe instead of -core.
* Rename -india to -indian, as it contains the Indian ocean islands
instead of the actual Asia/Kolkata zone for the mainland India.
* Add PROVIDES for the old package name
* Add 'Ocean' to all ocean zone titles.
* Make all zoneinfo-packages depend on zoneinfo-core, so that zone.tab,
the UTC based definitions and the still existing short zone codes are
always available.
* Clarify menuconfig menu as "Time Zone info"
