The error topic-alias-invalid was being sent if an MQTT v5 client published
a message with empty topic and topic alias set, but the topic alias hadn't
already been configured on the broker. This has been fixed to send a
protocol error, as per section 3.3.4 of the specification.
This is not specific to authentication, and allows plugins greater flexibility in what events they are interested in. It also adds message handling, and $CONTROL handling.

Change variable name for clarity. Remember to initialize bool (I'm bad at C).

New messages are now queued for clients when old ones are sent, rather than on every iteration of the main loop. This produces good performance improvements.
This adds the ability to separating bridge clean session settings between
the local and remote endpoints. Some broker implmentations refuse to allow
non-clean sessions, as they don't support storing messages to be sent to
the connecting broker. However, this doesn't mean that the local
broker can't be queueing messages to send _out_ to the remote broker.
This PR adds a new bridge connection setting, local_cleansession, that
allows controlling this split. Naming is chosen to be local_ in keeping
with the other local_ settings for bridges.
A test for the six cases of queued/not queued messages in both
directions is added, but v5 testing is currently disabled. The changes
to support the split are ~independent of protocol version.
