1) netconn_new_with_proto_and_callback() creates the semaphore and the

tcpip_apimsg() function pends on the op_completed semaphore with 0 time.
Just to ensure you get this right: '0' means infinite, not 'test and
return' -> the app task should wait for the tcpip_thread to complete the
function request.
