Add base AGL libqtappfw and Telephony supporteel_4.99.3eel/4.99.34.99.3

Implements several QtObject subclasses that wrap
functionality provided by the AGL Application Framework.

* Message provides facilities to create new AppFW requests
  and parse AppFw replies/events from a JSON buffer.
* MessageEngine provides a websocket message processing client
  that can send or receive Messages on a given websocket address.
* TelephonyMessage subclasses Message to provide accessors and
  methods specific to the AGL Telephony API.
* Telephony provides a complete set of Qt properties/signals/methods
  that expose the AGL Telephony functionality to Qt/QML applications.
  An application normally instantiates only this class and has no
  need to handle low-level AppFW messages.
