[8] Review request for 7117008: warning cleanup in sun.awt

[Artem Ananiev]

Hi, AWT team,

here is a fix for 7117008, which is about javac warning cleanup in the 
sun.awt package:

http://cr.openjdk.java.net/~art/jdk8/7117008/

As a part of this fix, I'm deleting several classes, which haven't been 
changed since 1995. They are not referenced anywhere in the JDK 
workspace, and they are not public API, so I consider them safe to 
remove. Please, let me know if you feel these files should stay in the 
workspace.

Thanks,

Artem
