1. bpo-15786: IDLE: Fix mouse clicks on autocompletetion window (python#… …

   …1811)
   
   The root problem was non-check for hide_event. When user clicks
   on autocomplete window (acw), root widget gets focusOut event, then triggers hide_window to
   close the acw. It should only be hide when acw is active, and acw didn't
   get focus at FocusOut event (this event bind on acw and widget), or when
   widget get a ButtonPress event (this event only bind on widget).
   
   MacOS  froze after double click on acw because when
   doubleclick_event try to hide window at the end, hide_window function
   destory whole acw, but tkinter didn't get focus back to widget. So set focus
   on widget first, then destory acw.
   
   Windows could not respond on double click event, because of the misbehavior
   of Configure event.  When acw was shown, tkinter called winconfig
   event multiple times.  That caused tkinter to not response to double
   click event.  When on Windows, unbind Configure event first
   time get into winconfig_event to prevent multiple call of this event.
   
   (cherry picked from commit 778b484)
