MBUS-2439: add support for audio service in SConstruct.top
ALLJOYN-2443 Fix check for endpoints for which session routing has not been set up.
GetHasRxSessionMsg() returns true iff the endpoint has processed a non-control message.
The check to be used is IsSessionRouteSetUp which checks if the DaemonRouter::AddSessionRoute() has been called for this b2b ep.
Also, this check is to be performed only for b2b eps.
ALLJOYN-2447 Restrict the endpoints added to m_authList/m_endpointList in TCPTransport::Connect().
ALLJOYN-2453 Fix catch-up of sessionless signals.
