Handle case where Tk_DestroyWindow is invoked
on clipboard and send windows.
* generic/tkClipboard.c (TkClipCleanup):
Invoke Tk_DestroyWindow to cleanup the
dispPtr->clipWindow. Call Tcl_Preserve
and Tcl_Release on the window to avoid an
invalid memory ref on shutdown.
* generic/tkEvent.c (Tk_HandleEvent):
Panic if XCreateIC is invoked twice for
the same window. This should never happen,
the check were just added to make sure it
does not since this could lead to crashes
in XCloseIM.
* generic/tkFocus.c (TkFocusDeadWindow):
Handle case where Tk_DestroyWindow is invoked
on clipboard and send windows.
* generic/tkOption.c (TkOptionDeadWindow): Ditto.
* generic/tkWindow.c (TkCloseDisplay): Move
deletion of dispPtr->winTable after TkpCloseDisplay
call since Tk_DestroyWindow uses it and could
be called by TkpCloseDisplay for clipboard/send windows.
Also invoke ckfree for the dispPtr instead of
doing it in TkpCloseDisplay.
(Tk_DestroyWindow): Check for a null winPtr->mainPtr
before doing certain cleanup tasks so the we can
invoke Tk_DestroyWindow on clipboard and send windows.
We need to do this so that XDestroyIC will get invoked
for the input contexts of each window.
* mac/tkMacXStubs.c (TkpCloseDisplay): Don't free
the displayPtr since this is now done in TkCloseDisplay.
* unix/tkUnixEvent.c (TkpCloseDisplay, OpenIM): Remove
conditional compilation around calls to XCloseIM
since I am confident that the crashes related to
input contexts has been fixed. Don't free
the displayPtr since this is now done in TkCloseDisplay.
* unix/tkUnixSend.c (TkSendCleanup): Invoke the
Tk_DestroyWindow method to cleanup the special
send window. This will call XDestroyIC and thereby
avoid a crash in XCloseIM. The send window needs
to be Tcl_Preserve and Tcl_Release to avoid an
invalid memory ref on shutdown.
* win/tkWinX.c (TkpCloseDisplay): Don't free
the displayPtr since this is now done in TkCloseDisplay.

(patch from Neil McKay).

set if -force is specified. This fixes the problem on Windows
where Tk does not activate the window if it already has focus.
