8264208: Console charset API

[calderast]

Backport of JDK-8264208.

Along with JDK-8238203 and JDK-8266774, prerequisite for a clean backport of JDK-8272352 to allow java to correctly parse Chinese characters in file paths and string arguments passed to java.exe.

Applies cleanly except for year changes in copyright headers.

This is an API change and not appropriate to back port to 11u.
