Now uses net_receive() with a proper timeout. Removed also
extra waits when sending data. Removed extra semaphores
and streamlined the code to act as fast as possible.

We must not touch uip_len(buf) value as Contiki IP stack
will use it to determine what it should do with the
received packet. So after we have received the packet,
we update separate datalen variable in net_buf that will
store the correct length of the packet.

Allow caller to specify a timeout in ticks while waiting
network data. The timeout value has following meaning:
TICKS_UNLIMITED wait forever
TICKS_NONE do not wait
value > 0 timeout value (only applicaple if
CONFIG_NANO_TIMEOUTS is defined)

Instead of aaaa::/64 address space which is part of global
IPv6 address space, use the 2001:db8::/32 which is meant
for documentation purposes and is not routable.

The echo server is listening on port 4242 and when it receives
UDP packet, it will reverse the data and send it back to the
caller. This can be used to verify that the IP stack is doing
something useful.
