Implement this behaviour by skipping the disks on traditional
commandline and hotplug them before resuming CPUs. That allows to use
the support for hotplugging of transient disks which inherently allows
sharing of the backing image as we open it read-only.
This commit implements the validation code to allow it only with buses
supporting hotplug and the hotplug code while starting up the VM.
When we have such disk we need to issue a system-reset so that firmware
tables are regenerated to allow booting from such device.

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This is available in QEMU with "ide-hd" and "scsi-hd" device

since we restrict usage to device=disk.
When this property is not set then QEMU's default behaviour
is to not report any rotation rate information, which
causes most guest OS to assume rotational storage.

The virtio-pmem is a virtio variant of NVDIMM and just like
NVDIMM virtio-pmem also allows accessing host pages bypassing
guest page cache. The difference is that if a regular file is
used to back guest's NVDIMM (model='nvdimm') the persistence of
guest writes might not be guaranteed while with virtio-pmem it
is.
To express this new model at domain XML level, I've chosen the
following:
<memory model='virtio-pmem' access='shared'>
<source>
<path>/tmp/virtio_pmem</path>
</source>
<target>
<size unit='KiB'>524288</size>
</target>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</memory>
Another difference between NVDIMM and virtio-pmem is that while
the former supports NUMA node locality the latter doesn't. And
also, the latter goes onto PCI bus and not into a DIMM module.

any NUMA nodes configured we can use memory-backend-* attributes

<memoryBacking/>). But what my original commits are missing is
allowing such configuration in our validator.

The validation callback always fetched a fresh copy of 'qemuCaps' to use
for validation which is wrong in cases when the VM is already running,
such as device hotplug. The newly-fetched qemuCaps may contain flags
which weren't originally in use when starting the VM e.g. on a libvirtd
upgrade.
Since the post-parse/validation machinery has a per-run 'parseOpaque'
field filled with qemuCaps of the actual process we can reuse the caps
in cases when we get them.
The code still fetches a fresh copy if parseOpaque doesn't have a
per-run copy to preserve existing functionality.
