Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

db11fcd174 net/net_pkt: Fully separate struct net_pkt from struct net_buf
- net_pkt becomes a stand-alone structure with network packet meta
  information.
- network packet data is still managed through net_buf, mostly named
  'frag'.
- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
  or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
  memory when TCP is enabled.

9e6a6f3bce net/mqtt: Add the "malformed" callback to the MQTT ctx structure
Add the malformed callback that will be executed when a message
is received and it does not follow the MQTT v3.1.1 spec.

There is another case when this callback may be executed: when
the IP stack reception buffer's size is not enough to hold an
MQTT message.

The publisher and subscriber parser routines are updated to make
use of this callback. Inline documentation is also updated.

4a17932d6a net/mqtt: Simplify the MQTT high-level API
1) Remove some variables pointing to user-provided data.
2) Pass the context structure instead of those variables.
3) Homogenize the use of "ctx" for all the callbacks receiving the
   struct mqtt_ctx * pointer.

Now users must use the CONTAINER_OF macro to access data required
by the MQTT callbacks.

ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

76e479974a net/mqtt: Allow an MQTT publisher app to receive msgs
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.

d490ff27ad net/mqtt: Add the mqtt_rx_publish routine
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.

edfaeba73d net/mqtt: Use the right data type
Use the appropriate data type for some variables:

- const input arguments
- int32_t instead of uint32_t for timeout
- uint8_t instead of int for variables that take just a few
  possitive values.
