bbe73173bb net: Use 2001:db8::/32 address space for sample apps
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.

f2886e2af3 net: uip: Traverse only through valid UDP connections
The uip.c:uip_process() was not checking the upper bound of
the UDP connection list when traversing the connection list.
Now the code checks the upper bound of the array (UIP_UDP_CONNS)
and will not go beyond the max number of items in the array.

This commit fixes the IPv4 branch, the IPv6 branch was already
fixed by commit 07a5959c2ae9ffce27092c2a0a6161111facdb6c

To make it easy to periodically verify that we have sane stack sizes
it's helpful to have some code to evaluate how much of the stacks are
used. There's already a CONFIG_INIT_STACKS option which pre-fills the
stacks with 0xaa bytes, so we make use of it and in case the option is
enabled run the extra code to evaluate how much of each stack was
used. The trigger for the evaluation is a disconnection event.

56ccfb3785 net: 15.4: Add 802.15.4 driver and 802.15.4 loopback radio driver
Enable 802.15.4 driver that receives the IPv6 packet, does header
compression on it and writes it to the 15.4 stack Tx FIFO.
The 15.4 Tx fiber will pick up the header compressed IPv6
6LoWPAN packet and fragment it into suitable chunks ready
to be sent to the 15.4 hw driver. The 15.4 stack Rx fiber picks
15.4 frames from 15.4 Rx FIFO (which are fed by 15.4 driver)
and reassembles the all fragmented packets and uncompress the
header and writes to the IP Rx FIFO.

The 15.4 loopback radio driver receives the 15.4 frames and
put it back to 15.4 Rx Fifo.
