[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.
