Should generate full type code info for Anys in RMI-IIOP

      Description

      The Java to IDL mapping has special cases for methods with parameters or return values of type

      java.io.Serializable
      java.io.Externalizable
      java.lang.Object

      They become Anys on the wire, and Anys should have full TypeCode information so that a non-Java IDL based client can still unmarshal them.

      See the attached test case (make sure to look at the README for the necessary hand modification of the stub class).

      The ORB currently generates an Any with a TypeCode of tk_value, and no other information -- the member count is 0. A Java-only world can handle this by calling extract_Value, getting the repository ID, loading the class, and performing normal RMI-IIOP unmarshaling.

      While working on a solution, keep in mind that fixing this correctly will introduce a huge performance implication both for time spent calculating the TypeCode tree, as well as the amount of information going on the wire. This is complicated by the fact that indirections are not allowed for top level type codes. See

      http://cgi.omg.org/issues/interop.html#Issue4294

      which is currently stalled because the discussion came to the conclusion that it would require a rev to GIOP 1.3.
