Converter: add cstring missing Sockets: * Starts a PIMPL idiom to safely cast Socket with the future SocketSsl and be able to return a class of type "Socket" whilst the interface returns effectively a SocketSsl. * Rename some function to be more cute to use like getDomain -> domain(). * SocketListener now owns completely sockets and must be moved to it, the dedicated function select() always return a socket owned by SocketListener. * Operation close is not needed anymore but the function stays in case it's needed.
