Fix L2CP socket connectionsv5.3.2
L2CP's psm (the RFCOMM port equivalent) was never published via SDP. Therefore the service client could not get the required information to connect to the server. After this patch Qt properly publishes the psm. Also, QBluetoothSocket::connect() initiated a service discovery to obtain the missing psm. Since the published SDP entry didn't contain one, protocolServiceMultiplexer() always returned 0 and another service discovery was initiated. This caused a crash inside QBluetoothSocket because the 1st QBluetoothServiceDiscoveryAgent instance was deleted in favor of the 2nd. The patch changes the client behavior such that it doesn't crash if the service discovery didn't turn up a valid psm/port. It improves the robustness in case of an error and avoids a second service discovery (which wouldn't turn up more information anyway). The bug only affected Bluez as it is the only platform supporting pure L2CP sockets. Last but not least a capability to test L2CP sockets was added to bttestui.
