6lowpan HC06 and HC01 compression/uncompression functions are
adapted to net_mbuf buffers. HC06 compression and uncompression
works properly. HC01 adapted to net_mbuf but functionality is
failing due to inproper IPv6 link local addresses. buf pointers
from net_mbuf and couple of net_mbuf calls are removed (which
are not used at the moment and saves memory from net_mbuf).

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.

If the udp packet was successfully delivered to the application,
and if the application did not want to send anything back to
sender, then then uip_slen(buf) will be 0.
In this case we MUST NOT set uip_len(buf) to 0 as that would
cause the net_buf to be released by RX fiber. In this case it is
application responsibility to release the buffer.

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.

This commit uses the simple UART driver to pass slip data between
qemu and host.
User needs to create a network device (tun) in host that is
connected to qemu via slip protocol. The tunslip6 process
acts as a gateway and passes packets between qemu and host.
See net/ip/contiki/tools/README file for details how to use and
configure the slip in host.
This is meant for testing the uIP stack.

For commands that generate an intermediate zero status (e.g.
HCI_LE_Create_Connection) we should allow for successful
bt_cmd_send_sync() completion at this point. Since the code treats a
NULL return buffer as failure we must provide an actual buffer to
indicate success. There's not really any useful information in the buf
for a cmd_status but passing it to the caller lets us notify of the
successful completion.
