JSON: Add support for echo option
The basic principle is to not return a JSON object freshly created from netlink responses, but just update the existing user-provided one to make sure callers get back exactly what they expect. To achieve that, keep the parsed JSON object around in a global variable ('cur_root') and provide a custom callback to insert handles into it from received netlink messages. The tricky bit here is updating rules since unique identification is problematic. Therefore drop possibly present handles from input and later assume updates are received in order so the first rule not having a handle set is the right one.
