Mike Kestner c93ecb7f88 2007-09-11 Mike Kestner <mkestner@novell.com>
* gtk/Gtk.metadata: virtual_method rules for GInterface generation.
	* generator/ReturnValue.cs (ToNative): new method for the virtual
	method generation.
	* generator/Parameters.cs (FromNative): null guarding.
	* generator/ManagedCallString.cs: rework for interface method
	generation including callback and error param support.
	* generator/CallbackGen.cs: Invoker support. new class that deals
	with persistence of native and wrapper delegates in native to managed
	callback method signatures.
	* generator/VirtualMethod.cs: support for generation of interface
	methods, and all the funky parameters that come with that.
	* generator/InterfaceGen.cs: Fill out the adapter implementation.
	* generator/MethodBody.cs: Initialize overload. Extend ThrowsException
	to support GError outside the last parameter slot.
	* glib/GInterfaceAttribute.cs: New attribute to mark interfaces and
	obtain adapter type.
	* glib/Object.cs (AddInterfaces): interface registration method.
	* glib/GInterfaceAdapter.cs: New abstract class for interface
	adapter generation.
	* glib/Makefile.am: add new files.
