Our FocusEvent class now has an additional "temporary" property to indicate
when focus change events are the side affect of some other operation as
opposed to the focus actually changing within a window.

A focusOut event should be temporary when:
 -- it results from a window being de-activated
 -- it results from a menu being posted (if it's delivered then on the platform)

All focusIn events on native components are permanent, so that is not
currently a problem.

On win32, the temporary bit on focusOut events is not being set properly.
You can see this by running the test, src/share/test/awt/ListenerTest.
