Details:

This is a small patch to let users of lwip in NO_SYS mode to restart the
system timeout handling. This is necessary when the lwip stack is not updated
for a while (to save runtime). In my current project I run (poll) the stack
only when necessary. The system time still progresses though, which leads to
huge jumps in sys_now(), resulting in premature timeouts. By calling
sys_restart_timeouts() after a longer phase of not processing the stack, this
can be prevented.
