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.

The mqtt_rx_publish is used to process incoming MQTT PUBLISH
messages. This routine performes the following steps:
- take ownership of the rx buffer containing the MQTT PUBLISH msg,
- call the MQTT parser routine, and
- determine, based on the incoming message's MQTT QoS,
the next action.

This commit adds one routine previously found at the DNS resolver
library. The net_nbuf_linear_copy routine allows to "linearize"
an IP stack network buffer. This routine is required by functions
that must jump between big chunks of data that in this case may
lie between many fragments. Tracking fragments may be a tedious
task, so getting a linear copy of the buffer will reduce code
complexity altough it increases memory consumption.
The DNS client library is updated to reflect these changes.

Currently, as only CC2520 device is supported: it will loop over the 16
channels present in 2.4Ghz spectrum. However, this will need refinement
as soon as other spectrums will be in use: L2 layer could request
capabilites from the device in order to know which range to use.
Scan result is done one at a time for now. It's unlikely going to fit
all production use case, so it's going to change in the future.

Let's make net stack having its own level of debugging through sys_log.
It replaces NET_DEBUG by NET_LOG_ENABLED, which is then semantically
better: someone wanting to log the errors might want that not only for
debugging.
Along with it, CONFIG_NET_LOG_GLOBAL option is added, in order to enable
all available logging in network stack. It is disabled by default but
might be found useful when warning/errors need to be logged, so it is
then unnecessary to selectively enable by hand all CONFIG_NET_DEBUG_*
options.
It is possible, locally, to override CONFIG_SYS_LOG_NET_LEVEL by setting
the level one want to NET_SYS_LOG_LEVEL. This can be useful on samples
or tests.

It's possible to know from which pool the nbuf comes from so
let's reduce nbuf size by removing its internal type attribute which
becomes then useless.
When a data buffer is not coming from nbuf data buffer pool, let's call
it "EXTERNAL", just to make debugging handling a little simple in the
code.

After commit 71c7c01819 about buf pool, we
started to get spurious behaviors on various places of the code on
different boards (a101, frdm...) BUT on qemu. Basically, outgoing ip/udp
packets were full of garbage. Or sometimes it was the abilitty to parse
incoming packet that was happening.
The difference between qemu and actualy boards is - afaik, at least, let
me know if I am wrong - that qemu provide initialized memory (full of
0s). Following this asssumption, this patch just reset the nbuf right
after it got allocated. And all started to work again as thought.
It's in fact a good thing to reset nbuf memory. Even before the above
commit: after being used more than once, a buffer would have ended up
with old content, and this could have been generating a bug. So let's be
on the safe side and always intialize nbuf content.

Minimal frame size is 60 bytes, but IP frame might be smaller than this
size minus the ethernet header. In that case, Ethernet frames are padded
so it does reach this minimal size. In this case, ethernet L2 should
update the buffer list so it remove the padding length from the whole.
