24914fcb4f add prototype of a tickless kernel 
only by entering the kernel, the tick counter will be updated
=> by using this feature, MetalSVM supports only LwIP's raw interface,
   because we have no guarantee that the tcpip thread will get computation time
=> no NETCONN & BSD socket support
=> no load balancing support
