overview: Try to do the right thing related to XDnD
Rather than expose a dizzying array of methods related to managing state that require infecting every user of the overview methods, try to do the sensible and smart thing internally. Now, the overview itself tracks when XDND drags start, and simply calling show, hide or toggle while an XDnD drag is in effect will show the overview, and will only take the grab until after the XDND drag ends. https://bugzilla.gnome.org/show_bug.cgi?id=663661
