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 a Netdev or a NetLegacy. The original meat of net_client_init() is moved to and simplified in net_client_init1(): Fields not common between -net and -netdev are clearly separated. Getting the name for the init functions is cleaner: Netdev::id is mandatory, and all init functions handle a NULL NetLegacy::name. NetLegacy::vlan explicitly depends on -net (see below). Verifying the "type=" option for -netdev can be turned into a switch. Format validation with qemu_opts_validate() can be removed because the visitor covers it. Relatedly, the "net_client_types" array is reduced to an array of init functions that can be directly indexed by opts->kind. (Help text is available in the schema JSON.) The outermost negation in the condition around qemu_find_vlan() was flattened, because it expresses the dependent code's requirements more clearly. VLAN lookup is avoided if there's no init function to pass the VLAN to. Whenever the value of type=... is needed, we substitute NetClientOptionsKind_lookup[kind]. The individual init functions are not converted yet, thus the original QemuOpts instance is passed transparently. v1->v2: - NetLegacy::name is optional. Tracked it through all init functions: they all handle a NULL name. Updated commit message accordingly. v2->v3: - NetLegacy::id is allowed and takes precedence over NetLegacy::name.
