Class BootstrapServerRequestDispatcher handles the requests coming to the
BootstrapServer. It implements Server so that it can be registered
as a subcontract. It is passed a BootstrapServiceProperties object
which contains
the supported ids and their values for the bootstrap service. This
Properties object is only read from, never written to, and is shared
among all threads.

The BootstrapServerRequestDispatcher responds primarily to GIOP requests,
but LocateRequests are also handled for graceful interoperability.
The BootstrapServerRequestDispatcher handles one request at a time.
