Attachment: An attempt using GdkDeviceManager

I tried to implement it in bug 1035774, but it doesn't work on Ubuntu 18.04 at least.  So I will handle it in a separate bug (here).

Attaching patch is what I did, it's just listening 'device-added' and 'device-removed' events for GdkDeviceManager but the event are never fired.

Another attempt I did is to use GdkSeat[1] instead of GdkDeviceManager, but it caused a linker error even if GDK_VERSION_MAX_ALLOWED in old-configure.in is upgraded.

I've decided to defer the implementation for GTK itself here in this bug.  The implementation needs some X11 functionalities, I think we need Wayland backend individually.
