NO_SYS==1: Use lwIP without OS-awareness (no thread, semaphores, mutexes or mboxes). This means threaded APIs cannot be used (socket, netconn, i.e. everything in the 'api' folder), only the callback-style raw API is available (and you have to watch out for yourself that you don't access lwIP functions/structures from more than one context at a time!)
