    tdf#105404 [API CHANGE] add index to accessiblity change event

Fix a handful of things related to accessibility objects being
destructed later than they should and consequently trying at access
other stuff that has already been destructed.

(1) AccessibleControlShape::disposing check the window still exists
(2) DocumentFocusListener::notifyEvent, handle INVALIDATE_ALL_CHILDREN
(3) hold DocumentFocusListener by weak reference in GtkSalData, so that
it dies when the related UI widgets die
