Reapply r50859 with chromeos fixes.

GTK: First draft of the unified cut/copy/paste and +/-/Fullscreen menu items.

Adds special menu item types that allow shoving buttons into them, along with
tracking which button is selected. We now are halfway to the mocks that the
chrome-ui-leads sent out.

+// GtkCustomMenu is a GtkMenu subclass that can contain, and collaborates with,
+// GtkCustomMenuItem instances. GtkCustomMenuItem is a GtkMenuItem that can
+// have buttons and other normal widgets embeded in it. GtkCustomMenu exists
+// only to override most of the button/motion/move callback functions so
+// that the normal GtkMenu implementation doesn't handle events related to
+// GtkCustomMenuItem items.
