RFR [8023130] (process) ProcessBuilder#inheritIO does not work on Windows

Hello everybody!

The method ProcessBuilder#inheritIO() is reported to not have any effect 
on Windows platform.
The same story is with redirectOutput/Input/Error(Redirect.INHERIT) methods.
As the result, standard in/out/err aren't inherited.

It turn out that the culprit is the CREATE_NO_WINDOW flag passed to 
MS doc says about this flag: "The process is a console application that 
is being run without a console window."

CREATE_NO_WINDOW flag was added with the fix for 
http://bugs.sun.com/view_bug.do?bug_id=4244515 to suppress a console 
window on a newly created process, when it is created from a program 
launched with javaw.exe.
Thus, I left this flag only for cases when the program doesn't have a 
console associated with it.

Would you please help review a fix for this problem?
