* 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. svn path=/trunk/gtk-sharp/; revision=85658
