Introduce stackable IO streams We currently have gitno for talking over TCP, but this needs to know about both plaintext and OpenSSL connections and the code has gotten somewhat messy with ifdefs determining which version of the function should be called. In order to clean this up and abstract away the details of sending over the different types of streams, we can instead use an interface and stack stream implementations. We may not be able to use the stackability with all streams, but we are definitely be able to use the abstraction which is currently spread between different bits of gitno.
