Bug 1438131 - Implement Drop on Wayland, r=jhorak
This patch implements Drop operation on Wayland/Gtk+. That's because drop operations are part
of clipboard on Wayland and we use our own paste clipboard handler on Wayland (Bug 1282015).
Wayland drop data are provided by wl_data_device_listener, it provides us drag and drop callbacks
which we route to nsDragService module.
