Instead of returning a QSharedPointer, return the same pointer. This
improves readability as well as using the subscription from a user

The ownership has to stay with the client though, otherwise behavior
is unexpected.

QMqttMessage stores all information about a published message being
received on a subscription. A user might be interested in more details,
hence provide all known details. Keep the class as lean as possible,
because its lifetime usually is very limited.

The class handles all subscription related items. Developers can use it
to manage the state of the subscription. Having a subscription object
simplifies message handling, there is no need to do a topic check for
each message received.
