net: Use hubs for the vlan feature
Stop using the special-case vlan code in net.c. Instead use the hub netclient to implement the vlan feature. The next patch will remove vlancode from net.c completely.
convert net_client_init() to OptsVisitor
The net_client_init() prototype is kept intact.
Based on "is_netdev", the QemuOpts-rooted QemuOpt-list is parsed as aNetdev or a NetLegacy. The original meat of net_client_init() is moved toand simplified in net_client_init1():...
