Init (start) the LwIP WSAPI server.

Start LwIP WSAPI http server, which means set TCP priority for new protocol control block, bind on TCP port and set callback for accepting new connection.

                        {
    lwsapi_dbg("lwsapi: start\n");
    struct tcp_pcb *pcb;
    err_t err;
 
    pcb = tcp_new_ip_type(IPADDR_TYPE_ANY);
    if (pcb == nullptr) {
        return ERR_MEM;
    }
 
    tcp_setprio(pcb, TCP_PRIO_MIN);
    err = tcp_bind(pcb, IP_ANY_TYPE, LIGHT_WSAPI_PORT);
    if (err != ERR_OK) {
        lwsapi_error("lwsapi: tcp_bind failed: %d", err);
        return err;
    }
 
    pcb = tcp_listen(pcb);
    if (pcb == nullptr) {
        lwsapi_error("lwsapi: tcp_listen failed");
        return ERR_CLSD;
    }
 
    tcp_accept(pcb, lwsapi_accept);
    return ERR_OK;
