Changes can be highlighted with below summary: * Split the original LocApiAdapter to LocAdapter and LocApi. Now different adapter implementations can flexibly connect to different LocApi; * LocApi continues to abstract the API binding to RPC or QMI; * MsgTask which creates and owns a msg Q and a thread, and it define a LocMsg base msg class. The handler pulls a msg out of the Q and calls its proc() method. This makes it possible for msg sender to keep the data in the msg encapsulated, as it no longer requires a central msg handler who must under- stand all data format. This used to be where all the compile time dependencies are tangled together; * Added Context to bundle MsgTask and LocApi; * Added LocDualContext specifically for the FLP Location Hal architecture requirement; * Placed all the base classes of the above in loc_core folder / loc_core namespace / libloc_core.so, so other libraries can easily use derive from here without having to pull in the loc_eng implementation, which is a large library to include or link to; Change-Id: I40abfba96dea76757c98530c1f5e076b34ba4ac7
