From the MQTT-SN spec:
6.5 Topic Name Registration Procedure
...
At any point in time a client may have only one
REGISTER message outstanding, i.e. it has to wait
for a REGACK message before it can register another
topic name.
...
6.9 Client’s Topic Subscribe/Un-subscribe Procedure
...
As for the REGISTER procedure, a client may have only
one SUBSCRIBE or one UNSUBCRIBE transaction open at a time.
...
Until now, the library did not comply with these requirements.
An additional "waiting" state for topics was introduced:
REGISTER, SUBSCRIBE and UNSUBSCRIBE as an extra step before
switching to REGISTERING, SUBSCRIBING and UNSUBSCRIBING. The
library now makes sure that only one topic can be REGISTERING
and only one topic can be in either SUBSCRIBING or UNSUBSCRIBING.
Additionally, requesting to UNSUBSCRIBE is now denied if the topic
is not yet SUBSCRIBED, to avoid weird race conditions.
Also, added two tests that verify this behavior.

This commit adds tests for the "Gateway Advertisement and Discovery"
process. This includes tests for handling SEARCHGW, GWINFO, and ADVERTISE
as well as manually adding a Gateway for use. Gateway pruning when
missing ADVERTISE messages is also tested.

Avoid to use debug log level for all modules and keep it only for MQTT
and NET related modules.
mr_canhubk3 board will fail to initialize the on-board watchdog within
the expected window causing a board reset, due to the amount of log
messages being printed. Other boards may also be affected.

Twister now supports using YAML lists for all fields that were written
as space-separated lists. Used twister_to_list.py script. Some artifacts
on string length are due to how ruamel dumps content.

Validate that basic lifecycling and usage of the MQTT-SN client
work correctly by providing a mocked MQTT-SN transport. Connection
setup and state changes are tested.
