<AWT Dev> 8029886: Change SecurityManager check{TopLevelWindow, SystemClipboardAccessAwtEventQueueAccess} to check AllPermission

[Artem Ananiev]

Hi, Alan,

the changes look fine to me.

A short quick question: what is the reason to introduce a new 
AWTPermissions class as a holder for various AWTPermission constants? We 
can have the same fields directly in AWTPermission. The only difference 
is that AWTPermission is in java.awt, while the new class is in sun.awt, 
but such a change seem to require a CCC request anyway...

Thanks,

Artem
