The password can now programmatically specified when using the 'keyboard-interactive' authentication method. Channels now respect their own window and maximum packet sizes, and report reasonable values to the server. The client name is now determined in a more robust manner. The authentication process will now only use those authentication methods that the server reports will have a chance of success. Various bugs have also been fixed.
