[7u-dev ONLY] RFR: [8057530] (process) Runtime.exec throws garbled message in jp locale

[Ivan Gerasimov]

Hello everybody!

This is a request for review of a fix which is applicable to 7u only.
The issue has already been addressed in 8 and later releases.

The fix is a combined backport of
https://bugs.openjdk.java.net/browse/JDK-8016579 , which addresses the 
problem with the encoding in windows console
and partial backport of
https://bugs.openjdk.java.net/browse/JDK-8001334 , which reorganizes the 
code at the files of our interest.

BUGURL: https://bugs.openjdk.java.net/browse/JDK-8057530
WEBREV: http://cr.openjdk.java.net/~igerasim/8057530/0/webrev/

The fix has been verified on the localized versions of Windows (jp, rus).

Thanks in advance,
Ivan
