qapi: convert netdev_add
This is not a full QAPI conversion, but an intermediate step.
In essence, do_netdev_add() is split into three functions:
1. netdev_add(): performs the actual work. This function is fully
converted to Error (thus, it's "qapi-friendly")
2. qmp_netdev_add(): the QMP front-end for netdev_add(). This is
coded by hand and not auto-generated (gen=no in the schema). The
reason for this it's a lot easier and simpler to with QemuOpts
this way
3. hmp_netdev_add(): HMP front-end.
This design was suggested by Paolo Bonzini.
