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. Bug-AGL: SPEC-1064 Change-Id: I2e41fb866bb4f867c81ccaf9bf33d627893879c8 Signed-off-by: Matt Porter <mporter@konsulko.com>
