Robert Shearman 2c3de6db24 - Make the wine_marshal_id structure more like the DCOM OBJREF
structure, by replacing the process id field by apartment id (OXID),
  changing the users of the process id field to use the new field and
  renaming the objectid field to oid.
- Fix StdMarshalImpl_UnmarshalInterface to invalidate and release its
  stub when doing a same apartment marshal.
