Now that the "name" parameter is gone, there is hardly any difference between NetLegacy and Netdev anymore, so we can drop NetLegacy and always use Netdev to simplify the code quite a bit. The only two differences that were really left between Netdev and NetLegacy: 1) NetLegacy does not allow a "hubport" type. We can continue to block this with a simple check in net_client_init1() for this type. 2) The "id" parameter was optional in NetLegacy (and an internal id was chosen via assign_name() during initialization), but it is mandatory for Netdev. To avoid that the visitor code bails out here, we have to add an internal id to the QemuOpts already earlier now.
