[krbdev.mit.edu #3929] support lazy launching of ccapi server

[Alexandra Ellwood via RT]

Fixed in new CCAPI implementation.  OS support must implement

cc_int32 cci_os_ipc (
                      cc_int32      in_launch_server,
                     cci_stream_t  in_request_stream,
                     cci_stream_t *out_reply_stream);

where in_launch_server determines whether or not the server is launched if not already running.
