* generator/ClassBase.cs : make MarshalType virtual. * generator/Parameters.cs : add Parameter class and Indexer. * generator/Signal.cs : Now use Parameters. (GetHandlerName): New abstraction of name handling. (GenerateDecls): use GetHandlerName. (GenComments): make private. (GenHandler): New. Generate custom event handlers and args. (Generate): use GenHandler. Pass args type to SignalHandler. * generate/SignalHandler.cs : store args type. Generate handler dependent args and use MulticastDelegate.DynamicInvoke. * generate/StructGen.cs : override MarshalType. * glib/SignalCallback.cs : store a MulticastDelegate and args type * sample/*.cs : use new DeleteEventHandler svn path=/trunk/gtk-sharp/; revision=5834
