<AWT Dev> [9] Review request for 8163583: [macosx] Press "To Back" button on the Dialog, the Dialog moves behind the Frame

[dmitry markov]

Hello,

Could you review a fix for jdk9, please?

     bug: https://bugs.openjdk.java.net/browse/JDK-8163583
     webrev: http://cr.openjdk.java.net/~dmarkov/8163583/webrev.00/

Problem description:
If toBack() method is invoked on dialog/frame which has not-null owner, 
the dialog/frame will be ordered below its owner/parent.

Fix:
The following methods in AWTWindow.m should be modified:
  - nativePushNSWindowToBack() add logic to perform a proper ordering 
for parent/child windows.
  - sendEvent() add logic to move parent windows to front and make sure 
that child windows are displayed above their nearest parents when the 
window is clicked by a mouse.

Thanks,
Dmitry
