[about 60% of the marshalling patch that I lost.
	 The rest to come tomorrow.]

	* generator/BoxedGen.cs, StructGen.cs: Move most of this to StructBase,
	delete large chunks duplicated from ClassBase.

	* generator/IGeneratable.cs: Add MarshalReturnType, FromNativeReturn.

	* generator/ClassBase.cs: Move ctor stuff here. Add a CallByName
	overload with no parameters for the "self" reference.

	* generator/EnumGen.cs, CallbackGen.cs: Implement new MarshalReturnType,
	  FromNativeReturn.

   * generator/Method.cs: Use container_type.MarshalType, CallByName, and
	  SymbolTable.FromNativeReturn when generating call and import sigs.

	* generator/OpaqueGen.cs: Added.

	* generator/Property.cs: Handle boxed and opaques differently.

	* generator/SymbolTable.cs: Update for the opaque stuff and the new Return
	methods. Also change GetClassGen to simply call the as operator.

	* glib/Boxed.cs: Update for struct usage -- this is now a wrapper for
	  the purposes of using with Value.

   * glib/Opaque.cs: Added. New base class for opaque structs.

	* glue/textiter.c, gtk/TextIter.custom: Remove.

	* gnome/Program.cs: Update for new struct marshalling.

	* parser/Metadata.pm: Use our own getChildrenByTagName.

	* parser/README: Update for new requirements (was out of sync with
	  build.pl)

	* parser/gapi2xml.pl: Hide struct like const in field elements.

	* parser/gapi_pp.pl: Handle embedded union fields (poorly).

	* sample/test/TestColorSelection.cs: Comment out null color tests
     for now.
