[RFC] iso-3177 changes

[Chris Leonard]

The iso-3177.def file is out-of-date.

There have been changes in 3177 that need to be reflected and some of
them will impact existing locales.

1) Relatively simple case A

Sudan is now Sudan and South Sudan

Fix: copy ar_SD locale, customize country information to create South
Sudan locale, adjust new country number for Sudan in ar_SD and
./locale/iso-3177.def

2) Slightly more complex case B

Netherlands Antilles is not in 3177 anymore, there are separate
entries for Aruba, Bonaire and Curacao now.

Fix: copy pap_AN locale (several times), customize country information
to create three locales, adjust country info in new locales and update
./locale/iso-3177.def

The question is what to do with pap_AN locale file?

"AN" no longer exists in 3177.

Do we deprecate that locale file or leave it as a legacy file for a
release or two?

I'll do the patching (it's relatively simple) and submit it list for
comment, but I need to know whether I delete pap_AN now, or wait on
it.

Do I do all iso-3177 changes as a single patch or break it up?
