Please review fix for JDK9.
webrev: http://cr.openjdk.java.net/~ssadetsky/8003399/webrev.00/
bug: https://bugs.openjdk.java.net/browse/JDK-8003399

JDK uses legacy WINAPI special folders calls while MS introduced a new 
interfaces IKnownFolder and IShellLibrary to manage special folder 
locations and the new Libraries functionality in Windows 7 is not 
backward compatible with old special folders CSIDL.

Since it is too expensive to migrate AWT shell to the new interfaces and 
still they are not supported in java.io the solution is to map virtual 
folder PIDL to the Known Folder GUID and replace libraries links with 
the default library save location. Thus the File save dialog will be 
able to work with any Libraries registered in the system (Windows 
Libraries concept assumes that Libraries can be added arbitrary).
The resulting code should be compatible with older Windows versions 
because the new COM interfaces are called only if they are available and 
a Libraries link has been actually requested.

A test scenario is added to check that all available Libraries links are 
converted into filesystem paths.
