We finally have all the required pieces for doing a type-safe representation of netdev_add as a flat union, where the discriminator 'type' now selects which additional members may appear in the "arguments" JSON object sent over QMP, while making no changes to the set of previously-valid QMP commands that would work, and without breaking command line parsing.
