<AWT Dev> AWT impact of deprecating/changing SecurityManager#checkTopLevelWindow, checkSystemClipboardAccess, checkTopLevelWindow

[Alan Bateman]

This is a follow-up to thread from June [1] where I proposed deprecating 
the SecurityManager checkTopLevelWindow, checkSystemClipboardAccess, 
checkTopLevelWindow methods.

At the time then Anthony agreed with the spec change but I didn't come 
back with a final webrev and get the change pushed. I've been on my "to 
do" list for a while and I'm only getting to it now. Here's the updated 
webrev:

The spec changes are the same as what we had in June, it's just a 
re-based patch. I've also added a test and I'm open to suggests as to 
whether to put this (alternatively it can be split up, with separate 
tests for Toolkit and Window if needed).

Thanks,
Alan.
