<i18n dev> [9] RFR: 8148346: Reduce number of packages in jdk.localedata module

[Naoto Sato]

Hello,

Please review the fix to the following issue:

https://bugs.openjdk.java.net/browse/JDK-8148346

The proposed change is located at:

http://cr.openjdk.java.net/~naoto/8148346/webrev.00/

Vast majority of the changes are changing package names. They used to be 
lang/ctry structure, which bloats the number of locale data package 
names to hundreds. Now it comes down to 8 packages with this fix.
