CORBA26 — Components FTF: TypeCodeFactory

The third part of the adopted CCM submission (orbos/99-07-03)
moves all the create_..._tc operations from the ORB interface
to a new PIDL interface, CORBA::TypeCodeFactory.

This change breaks source-compatibility: source code that creates
typecodes with a pre-CORBA 3.0 ORB will need to be updated to use
a CORBA 3.0 ORB with such a TypeCodeFactory interface.

And there is no clear benefit from this update:

• ORB is still PIDL – it even creates an additional PIDL
  interface.
• type code kinds are not more extensible (TCKind is still an
  enum)

I suggest to undo this update, i.e. keep the create_..._tc
operations on the CORBA::ORB interface.
