* atk/Atk.metadata: markup all the Ref* methods to indicate owned refs.
	* generator/ReturnValue.cs: Add owned object ToNative handling.
	* generator/VirtualMethod.cs: Split ToNative call from managed method
	invocation to avoid duplicate calls in null checking scenarios.
	* glib/Object.cs: add OwnedHandle property for use by language binding
	code which needs to pass owned refs to native methods.
