If the stack is sending network packets by itself, like when
sending router or neighbor solicitation messages, then remember
the original length of the message. This is important because
uIP stack will clear the length of the sent message after it
is sent.
After this change, the lower level drivers can use
the net_buf_datalen() to get the original length of the
buffer. The issue is seen because uIP stack is running in
different fiber than the network device driver.

The Contiki etimers need polling which is handled by this fiber.
This fiber sleeps until next etimer is to be triggered. If the wakeup
time is long, we wait max 60 sec so that new timers can be triggered
also. This 60 sec timeout might be too long and require tweaking when
we know how the system behaves.
If there are no etimer event in the system, then the timer fiber
will only sleep 2 seconds before checking the timers again. This
interval might need tweaking also.
