vhost-user: return failure if backend crash when live migration
Live migration should be terminated if the vhost-user backend crashes before the migration completes.
Specifically, since the vhost device will be stopped when VM is stopped before the end of the live migration, in current implementation if the backend crashes, vhost-user device set_status() won't return failure, live migration won't perceive the disconnection between QEMU and the backend.
When the VM is migrated to the destination, the inflight IO will be resubmitted, and if the IO was completed out of order before, it will cause IO error.
To fix this issue: 1. Add the return value to set_status() for VirtioDeviceClass. a. For the vhost-user device, return failure when the backend crashes. b. For other virtio devices, always return 0. 2. Return failure if vhost_dev_stop() failed for vhost-user device.
If QEMU loses connection with the vhost-user backend, virtio set_status() can return failure to the upper layer, migration_completion() can handle the error, terminate the live migration, and restore the VM, so that inflight IO can be completed normally.

include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST
Now that all of the Property arrays are counted, we can remove the terminator object from each array. Update the assertions in device_class_set_props to match.
With struct Property being 88 bytes, this was a rather large form of terminator. Saves 30k from qemu-system-aarch64.

This patch drops the name parameter for the virtio_init function.
The pair between the numeric device ID and the string device ID (name) of a virtio device already exists, but not in a way that lets us map between them.
This patch lets us do this and removes the need for the name parameter in the virtio_init function.

qdev: Unrealize must not fail
Devices may have component devices and buses.
Device realization may fail. Realization is recursive: a device's realize() method realizes its components, and device_set_realized() realizes its buses (which should in turn realize the devices on that bus, except bus_set_realized() doesn't implement that, yet).
When realization of a component or bus fails, we need to roll back: unrealize everything we realized so far. If any of these unrealizes failed, the device would be left in an inconsistent state. Must not happen.
device_set_realized() lets it happen: it ignores errors in the roll back code starting at label child_realize_fail.
Since realization is recursive, unrealization must be recursive, too. But how could a partly failed unrealize be rolled back? We'd have to re-realize, which can fail. This design is fundamentally broken.
device_set_realized() does not roll back at all. Instead, it keeps unrealizing, ignoring further errors.
It can screw up even for a device with no buses: if the lone dc->unrealize() fails, it still unregisters vmstate, and calls listeners' unrealize() callback.
bus_set_realized() does not roll back either. Instead, it stops unrealizing.
Fortunately, no unrealize method can fail, as we'll see below.
To fix the design error, drop parameter @errp from all the unrealize methods.
Any unrealize method that uses @errp now needs an update. This leads us to unrealize() methods that can fail. Merely passing it to another unrealize method cannot cause failure, though. Here are the ones that do other things with @errp:
* virtio_serial_device_unrealize()
Fails when qbus_set_hotplug_handler() fails, but still does all the other work. On failure, the device would stay realized with its resources completely gone. Oops. Can't happen, because qbus_set_hotplug_handler() can't actually fail here. Pass &error_abort to qbus_set_hotplug_handler() instead.
* hw/ppc/spapr_drc.c's unrealize()
Fails when object_property_del() fails, but all the other work is already done. On failure, the device would stay realized with its vmstate registration gone. Oops. Can't happen, because object_property_del() can't actually fail here. Pass &error_abort to object_property_del() instead.
* spapr_phb_unrealize()
Fails and bails out when remove_drcs() fails, but other work is already done. On failure, the device would stay realized with some of its resources gone. Oops. remove_drcs() fails only when chassis_from_bus()'s object_property_get_uint() fails, and it can't here. Pass &error_abort to remove_drcs() instead.
Therefore, no unrealize method can fail before this patch.
device_set_realized()'s recursive unrealization via bus uses object_property_set_bool(). Can't drop @errp there, so pass &error_abort.
We similarly unrealize with object_property_set_bool() elsewhere, always ignoring errors. Pass &error_abort instead.
Several unrealize methods no longer handle errors from other unrealize methods: virtio_9p_device_unrealize(), virtio_input_device_unrealize(), scsi_qdev_unrealize(), ... Much of the deleted error handling looks wrong anyway.
One unrealize methods no longer ignore such errors: usb_ehci_pci_exit().
Several realize methods no longer ignore errors when rolling back: v9fs_device_realize_common(), pci_qdev_unrealize(), spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(), virtio_device_realize().

Include hw/qdev-properties.h less
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h).
Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead.
hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.
While there, delete a few superfluous inclusions of hw/qdev-core.h.
Touching hw/qdev-properties.h now recompiles some 1200 objects.
