Updates in test-ios-sofia-cli: fixed most of the warnings, instead of using STDIN to send commands (which is not applicable to iOS), I created a pipe as a communication channel between the iOS core application and the separate thread running sofia sip event loop, fixed an issue with std::list that was allocated using su_zalloc() which was problematic. In the end I was finally able to run successfully on the iphone and perform registration with RestComm using authentication. I now have issues performing an invite to alice residing in hard sip phone
