PSS — PSS FTF issue: ConnectorRegistry made redundant by

The Joint Revised Portable Interceptor submission (document orbos/99-12-02)
defines a new operation on the ORB interface, register_initial_reference.
With this operation, there is no need for a separate ConnectorRegistry
(local) object obtained from ORB::resolve_initial_references.

In practice, I expect that calls to register_initial_reference will
occur behind the scene – not in the middle of application code.

For example with our new ORB (Orbix 2000), it is possible to use
configuration to control the behavior of resolve_initial_references,
in particular have resolve_initial_references dynamically load and
initialize a plug-in. The plug-in per-ORB initialization calls
register_initial_reference on the given ORB instance.
