qapi: Unbox base members Rather than storing a base class as a pointer to a box, just store the fields of that base class in the same order, so that a child struct can be directly cast to its parent. This gives less malloc overhead, less pointer dereferencing, and even less generated code. Compare to the earlier commit 1e6c1616a "qapi: Generate a nicer struct for flat unions" (although that patch had fewer places to change, as less of qemu was directly using qapi structs for flat unions). It also allows us to turn on automatic type-safe wrappers for upcasting to the base class of a struct. Changes to the generated code look like this in qapi-types.h: | struct SpiceChannel { |- SpiceBasicInfo *base; |+ /* Members inherited from SpiceBasicInfo: */ |+ char *host; |+ char *port; |+ NetworkAddressFamily family; |+ /* Own members: */ | int64_t connection_id; as well as additional upcast functions like qapi_SpiceChannel_base(). Meanwhile, changes to qapi-visit.c look like: | static void visit_type_SpiceChannel_fields(Visitor *v, SpiceChannel **obj, Error **errp) | { | Error *err = NULL; | |- visit_type_implicit_SpiceBasicInfo(v, &(*obj)->base, &err); |+ visit_type_SpiceBasicInfo_fields(v, (SpiceBasicInfo **)obj, &err); | if (err) { (the cast is necessary, since our upcast wrappers only deal with a single pointer, not pointer-to-pointer); plus the wholesale elimination of some now-unused visit_type_implicit_FOO() functions. Without boxing, the corner case of one empty struct having another empty struct as its base type now requires inserting a dummy member (previously, the 'Base *base' member sufficed). And now that we no longer consume a 'base' member in the generated C struct, we can delete the former negative struct-base-clash-base test.

qmp: Wean off qerror_report() The traditional QMP command handler interface int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data); doesn't provide for returning an Error object. Instead, the handler is expected to stash it in the monitor with qerror_report(). When we rebased QMP on top of QAPI, we didn't change this interface. Instead, commit 776574d introduced "middle mode" as a temporary aid for converting existing QMP commands to QAPI one by one. More than three years later, we're still using it. Middle mode has two effects: * Instead of the native input marshallers static void qmp_marshal_input_FOO(QDict *, QObject **, Error **) it generates input marshallers conforming to the traditional QMP command handler interface. * It suppresses generation of code to register them with qmp_register_command() This permits giving them internal linkage. As long as we need qmp-commands.hx, we can't use the registry behind qmp_register_command(), so the latter has to stay for now. The former has to go to get rid of qerror_report(). Changing all QMP commands to fit the QAPI mold in one go was impractical back when we started, but by now there are just a few stragglers left: do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(), qmp_netdev_add(), do_device_add(). Switch middle mode to generate native input marshallers, and adapt the stragglers. Simplifies both the monitor code and the stragglers. Rename do_qmp_capabilities() to qmp_capabilities(), and do_device_add() to qmp_device_add, because that's how QMP command handlers are named today.

QemuOpts: Wean off qerror_report_err() qerror_report_err() is a transitional interface to help with converting existing monitor commands to QMP. It should not be used elsewhere. The only remaining user in qemu-option.c is qemu_opts_parse(). Is it used in QMP context? If not, we can simply replace qerror_report_err() by error_report_err(). The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are clearly not in QMP context. The uses in vl.c aren't either, because the only QMP command handlers there are qmp_query_status() and qmp_query_machines(), and they don't call it. Remaining uses: * drive_def(): Command line -drive and such, HMP drive_add and pci_add * hmp_chardev_add(): HMP chardev-add * monitor_parse_command(): HMP core * tmp_config_parse(): Command line -tpmdev * net_host_device_add(): HMP host_net_add * net_client_parse(): Command line -net and -netdev * qemu_global_option(): Command line -global * vnc_parse_func(): Command line -display, -vnc, default display, HMP change, QMP change. Bummer. * qemu_pci_hot_add_nic(): HMP pci_add * usb_net_init(): Command line -usbdevice, HMP usb_add Propagate errors through qemu_opts_parse(). Create a convenience function qemu_opts_parse_noisily() that passes errors to error_report_err(). Switch all non-QMP users outside tests to it. That leaves vnc_parse_func(). Propagate errors through it. Since I'm touching it anyway, rename it to vnc_parse().
