* atk/Object.custom: Track API changes in GLib.Signal.

* glib/Signal.cs: AddEmissionHook binding (for closing #386950), and
  change API of Emit to mimic the detailed_signal pattern.
* glib/GType.cs: GType.FromName: new wrapper for native call.
* glib/ObjectManager.cs: Use the new FromName managed method.
