Add support for 802.15.4 dummy radio driver to send frames
through qemu uart and and receive frames through uart. So
two qemus can send and receive 802.15.4 frames.

from generated kernel.

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.

Move packetbuf from net_buf to net_mbuf, update 802.15.4 stack
with net_mbuf (which is smaller in size, and mostly wrapper for
packetbuf) and split sicslowpan(ipv6/sicslowpan.c|h) functionality
to compression and fragmentataion. This patch contains
null_compression and null_fragmentation which is exactly what
uip_driver.c|h does.

This mega patch changes how Contiki uses buffers. In standard
Contiki there is only couple of static and global buffers.
This makes the stack non-reentrant and only usable in one
thread. This patch replaces the global buffer with buffer
supplied by caller (net_buf.h). The Contiki stack is still not
fully re-entrant after this (packet reassembly needs more TLC)
but it is a good start.
