Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions. Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it. Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).
