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.

This patch adds the mqtt_subscriber_parser routine and modifies the
mqtt_init routine to allow an MQTT subscriber app to receive MQTT 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.

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.

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.

This commit changes some function signatures found at the private
MQTT Packet Lib. Input arguments representing arrays can be considered
'const', avoiding compiler warnings when passing "const arrays" in
MQTT applications.
