[9] RFR: 8180375: Rename <baseName>Provider to <packagename>.spi.<simpleName>Provider

[Naoto Sato]

Hello,

Please review the changes to the following issue:

https://bugs.openjdk.java.net/browse/JDK-8180375

The proposed fix is located at:

http://cr.openjdk.java.net/~naoto/8180375/webrev.00/

This is to change the package name of the resource bundle provider to a 
different one, by appending ".spi" to the original package name. This 
change effectively avoids possible split package issue if resource 
bundles are provided from other named modules.
