If the destination IP address is loopback, then bypass
the L2 layer and directly feed the IP packet back to us.
If the destination IP address is unspecified, then
drop the packet.
All this is only done if CONFIG_NET_IP_ADDR_CHECK is
set as this extra processing can be unnecessary if
it is always known what addresses the device is going
to use. By default the address checking is enabled.

This commit adds the MQTT high-level API with Quality-of-Service
support. The following MQTT messages are covered by this commit:
CONNECT (tx), DISCONNECT (tx), PUBACK (tx, rx), PUBCOMP (tx, rx),
PUBREC (tx, rx), PUBREL (tx, rx), PUBLISH (tx), PINGREQ (tx),
SUBSCRIBE (tx), UNSUBSCRIBE (tx), CONNACK (rx), PINGRESP (rx),
SUBACK (rx) and UNSUBACK (rx).
Where 'tx' stands for transmission: routines that create and send
messages. 'rx' stands for reception: routines that receive an RX
buffer from the IP stack and parse the MQTT mesage contained in
that buffer.

For certain scenarios, such as handling TCP active close, where the
state group {FIN_WAIT_1, FIN_WAIT_2, CLOSING, TIME_WAIT} can be reached
from more than one state (ESTABLISHED and SYN_RCVD respectively), it's
cleaner to handle all the transitions inside a single callback
function.

This transitions a connection to FIN_WAIT_1 state if it was in either
SYN_RCVD or ESTABLISHED states and the local peer decided to close the
connection.
A timer is started to close the connection after 2 MSL (which is 120
seconds; this might be easily tunable through kconfig). No transition
from this state to FIN_WAIT_2, CLOSING, or TIME_WAIT are implemented on
this change: oncoming changes will implement the rest of this
machinery.

If a packet with the FIN flag is received while in ESTABLISHED estate,
transition to CLOSE_WAIT and send the ACK as usual.
The act of preparing a segment in CLOSE_WAIT state will automatically
transition the TCP context to the LAST_ACK state. Next time a packet
comes in with the ACK flag set, put the context.
