* generator/ImportSignature.cs : out param handling fix.
	* generator/Makefile.am : kill StringGen.cs.
	* generator/MethodBody.cs : simplify out param handling.
	* generator/StringGen.cs : kill it, now using MarshalGen.
	* generator/SymbolTable.cs : make non-const strings use an appropriate
	MarshalGen.  Non-const strings are now correctly marshaled as Utf8.
	* glib/Marshaller.cs : add some utf8-fu for strdup/free marshaling.
	Add a method to alloc/copy structs to native memory, unused yet.
	* gtk/Gtk.metadata : partially fix a broken delegate.
