<i18n dev> RFR: 8032446: Support Unicode 7.0.0 in JDK 9

[Yuka Kamiya]

Hello,

Please review the fix for 8032446 to support Unicode 7 in JDK 9.

https://bugs.openjdk.java.net/browse/JDK-8032446
http://cr.openjdk.java.net/~peytoia/8032446/webrev.00/

- Internal review for both open & closed parts has been completed.
- Changes in sun.text.* packages are mostly porting from ICU4J. (Thank
you very much, ICU4J project.)
- Because Unicode 8 was released last month, this fix will be
overwritten (partially) in near future.

Thanks,
