[9] RFR 8038436: Re-examine the mechanism to determine available localedata and cldrdata

[Naoto Sato]

Hello,

Please review the changes for the following issue:

https://bugs.openjdk.java.net/browse/JDK-8038436

The proposed changes are located at:

http://cr.openjdk.java.net/~naoto/8038436/webrev.3/

The idea is to introduce an SPI so that supported locales are 
dynamically searched at runtime, not depending on the existence of 
physical jar files.

I'd appreciate it if build folks could review the makefile related 
changes, i18n forks to review locale framework files, and Mandy from 
modularization point of view.

Naoto
