QAPI visitors. The lazy way: use the QObject output visitor to convert the QAPI type (here: NetdevInfo) to QObject, then qobject_to_json() to convert to JSON text. If you don't want JSON, replace qobject_to_json(). Perhaps you can create something that's generally useful for HMP, not just "info network". I'd pick keyval_parse() syntax. The detour through QObject creates and destroys a rather fat temporary data structure. Tolerable when the amount of data is small. An output visitor that directly creates the string is more efficient. Takes a bit more code, though. I intend to post one for JSON, to reduce QMP's malloc gluttony.
