Having TX buffers split into numerous pools has the downside of
increased memory consumption. This patch takes the initial step to
consolidate these pools into a single one, saving about 248 bytes of
RAM for a basic configuration.

The tcp_synack_received() function ends with a call to send_ack().
However, if we don't update the sequence and ACK values, we'll send back
headers with 0 values and the destination will try resending over and
over.
Fix this by saving the seq and ack values when a TCP_SYN is flagged
in the header (which should be the case almost any time this function
is used as a callback).

On accepting a new connection, the stack does an odd "swap" trick
where it updates the struct net_tcp record on the *listening* context
with the values from the new connection, and then swaps it with the
empty one that got allocated for the *new* context.
Unfortunately this swap forgot to swap the net_tcp "context" field
backpointers, so the net_context retrieved at runtime was for the
wrong connection. Surprisingly, this actually almost worked for a
long time, except that the destination address would be wrong in the
newer setup.

The source address for a TCP SYNACK must (obviously) be the same as
the destination address of the SYN that produced it. But the existing
IP packet creation routines would simply fill in a default address
from the net_context struct, which is correct for *established*
connections, but for the listening socket is generally INADDR_ANY
(i.e. all zeroes) and will result in an arbitrary choice for source
address (e.g. a link-local address on the same interface) which can
easily be wrong.
So we need to pass the correct address all the way down from the SYN
packet handler code through the net_ipv*_create() packet creation
functions. This requires lots of API plumbing, but relatively little
logic change.

When a CNAME is part of the DNS answer RR, sometimes a label with
a pointer is found. The CNAME must be reused to create a new DNS
query and that CNAME will become the new DNS Query QNAME. This new
QNAME must not include pointers.
This patch introduces the qname_copy routine that "linearizes" a
given QNAME (perhaps with pointers).
The dns_read routine is also updated to reflect these changes.

Changes applied by this patch:
- Add the mqtt_publisher_parser routine
- Add the MQTT_PACKET_TYPE macro to get the MQTT msg packet type
(required by mqtt_publisher_parser)
- Add the mqtt_linearize_buffer (required by mqtt_publisher_parser)
- Add the mqtt_recv callback for reception
- Modify the mqtt_init routine to install the reception callback
The mqtt_publisher_parser routine is a callback used internally
to execute the appropriate mqtt_rx routine. Only the following
messages are handled by this routine:
MQTT_CONNACK, MQTT_PUBACK, MQTT_PUBREC, MQTT_PUBCOMP and MQTT_PINGRESP.
On error, it executes the ctx->malformed cb, if defined.
This commit also introduces the mqtt_linearize_buffer routine that
will be used to linearize an IP stack fragmented buffer. This patch
makes use of the net_nbuf_linear_copy routine to linearize the
incoming buffer. mqtt_rx_xxxx routines are also updated to handle
linear buffers (no fragmentation).
Currently, all the network protocol routines assume that the input
buffer is not fragmented. Future versions will remove that assumption
and the mqtt_linearize_buffer routine will be removed as well.
Public MQTT API is not affected by this patch.
