[alexander stepanov]

Hello,

Could you please review the webrev:
http://cr.openjdk.java.net/~avstepan/8044429/

This is the 1st portion of functional AWT modality tests prepared for 
migration to OpenJDK repository in accordance with
https://bugs.openjdk.java.net/browse/JDK-8044429

Some helper classes were moved too.

The tests were checked on Ubuntu 14.04, Solaris 11, and Windows 7.

At the moment the tests are failing on Mac OS X due to
https://bugs.openjdk.java.net/browse/JDK-7125054
https://bugs.openjdk.java.net/browse/JDK-8047179

Thanks,
Alexander
