Updates in test-ios-sofia-cli: fixed some issues with the pipes, so that we can have full duplex communication between the core App and Sofia SIP thread. Added another run loop source in main thread's run loop to monitor the incoming data from sofia SIP to the core App through the pipe. That way we avoid another thread and the I/O multiplexing is much simpler. Started working on a first step of the library, which is hinding the cli completely and exposing a clean API
