[8]Review Request: 7162007: Clean up i18n related caches

[Naoto Sato]

Hello,

(To build-dev folks, I am sending this to you as the change includes one 
modification in make directory. It is just simply adding a new Java 
file, so I think it won't affect the new build-infra structure)

Please review the changes for this issue:

http://bugs.sun.com/view_bug.do?bug_id=7162007

Currently locale sensitive services cache their data in a very ad-hoc 
manner, scattered everywhere. This issue intends to consolidate them 
into a centralized location in sun.util.locale.provider package.

The proposed changeset is located at:
