rework message hierarchy

Rework message hierarchy with the final objective
of splitting libqtappfw into several libraries.
This commit carries the following changes:
- Simplify message hierarchy, keeping abstract
Message class, adding specialization for call and
event messages, keeping ResponseMessage, and
removing all module specific specializations.
- Add MessageFactory class to create message
objects.
- Change messages life cycle: using smart pointers
and removing QObject from message hierarchy (a
Message is not a QObject anymore and thus
'deleteLater()' is not available).
- Adapt all modules to use new message hierarchy.
- Keep ResponseMessage original constructor to
avoid breaking TaskManager.
- Message constructors have been kept public, but
will go private on a follow-up patch (once
TaskManager class has been modified to use new
MessageFactory).
