Introduce the public includes for the QMF interfaces.

Rename Agent to AgentEngine to differentiate the API from the underlying engine.

Note that some of these public headers will overlap with the emerging "messaging"
API (notably Connection.h and ConnectionSettings.h).  It is desirable that these
components of the API become common between "messaging" and "qmf".  As such, once
the differences are reconciled, they will most likely be removed from the qmf space
and placed in the messaging space.
