Hi,

"Host Memory Backends" and "Memory devices" queue ("mem"):
- Memory device cleanups (especially around machine initialization)
- "x-ignore-shared" migration support for virtio-mem
- Add an abstract virtio-md-pci device as a common parent for
virtio-mem-pci and virtio-pmem-pci (virtio based memory devices)
- Device unplug support for virtio-mem-pci

virtio-md-pci: Support unplug requests for compatible devices

Let's support unplug requests for virtio-md-pci devices that provide
a unplug_request_check() callback.

We'll wire that up for virtio-m

virtio-md-pci: Support unplug requests for compatible devices

Let's support unplug requests for virtio-md-pci devices that provide
a unplug_request_check() callback.

We'll wire that up for virtio-mem-pci next.

virtio-md-pci: Handle unplug of virtio based memory devices

While we fence unplug requests from the outside, the VM can still
trigger unplug of virtio based memory devices, for example, in Linux
doing on a virtio-mem-pci device:
# echo 0 > /sys/bus/pci/slots/3/power

While doing that is not really expected to work without harming the
guest OS (e.g., removing a virtio-mem device while it still provides
memory), let's make sure that we properly handle it on the QEMU side.

We'll add support for unplugging of virtio-mem devices in some
configurations next.

pc: Factor out (un)plug handling of virtio-md-pci devices

Let's factor out (un)plug handling, to be reused from arm/virt code.

Provide stubs for the case that CONFIG_VIRTIO_MD is not selected because
neither virtio-mem nor virtio-pmem is enabled. While this cannot
currently happen for x86, it will be possible for arm/virt.
