Restore the behavior introduced in
598163e5, which regressed in commit
5a3442bf.

So that we clear its pointer also in case somebody else calls
gtk_container_remove() on the button.
Fixes criticals at startup in e.g. Nautilus.

This reverts commit 6e6487b4.

Since we explictly call popup_menu with NULL when it's
keyboard-activated, we need to be careful and not access event->device
without checking for event != NULL before.

As used in Totem and gnome-contacts. The widget
takes either a GtkMenu or a GMenuModel to construct
its menu, and can be given a parent widget to use to
