This is how things would look like if we move Connection to Utility instead. I
needed to do two things to make this happen:
- Keep Connection::CreateDefaultConnection in Host (now known as
Host::CreateDefaultConnection), because this actually creates concrete
instances).
- Move IOObject to Utility as well. Connection interface was depending on this
class. Although theoretically a forward declaration could suffice, we still
shouldn't depend on stuff forward-declared in another module. The same
rationale can apply to this class as well -- it's an abstract interface, which
can live in Utility, and all concrete instances can (hopefully) stay in Host.
