VM drivers may need to store additional private data to the status XML
so that it can be restored after libvirtd restart. Since not everything
is needed add a callback infrastructure, where VM drivers can add only
stuff they need.
Note that the private data is formatted as a <privateData> sub-element
of the <disk> or <backingStore> <source> sub-element. This is done since
storing it out of band (in the VM private data) would require a complex
matching process to allow to put the data into correct place.

If the vhost-scsi device file cannot be found, the generic error
"error: An error occurred, but the cause is unknown"
is returned. Let's add a real error message to make it clear
why the failure occurred.
We cannot be sure someone initialized the passed *vhostfd and we
certainly don't want or need to be calling VIR_FORCE_CLOSE on what
probably is -1. So let's just return -1 immediately.
Commit id '70249927b' neglected to cover this case because the test
had taken the "shortcut" to already add the <address>; however, when
the PCI address assignment code was adjusted by commit id '70249927'
the vhost-scsi (VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI_HOST) wasn't
covered thus returning a 0 for pciFlags. So I altered the tests too
to make sure it doesn't happen again.
Previously the qemuxml2xmloutdata was a softlink to the source
qemuxml2argvdata, so I unlinked and recreated the output file to
force generation of the adddress. Without the test changes, an
address generation returns:
libvirt: Domain Config error : internal error: Cannot automatically
add a new PCI bus for a device with connect flags 00
if an address was supplied in the test, a restart of libvirtd or
edit of a guest would display the following opaque message:
warning : qemuDomainCollectPCIAddress:1237 :
qemuDomainDeviceCalculatePCIConnectFlags() thinks that the device
with PCI address 0000:00:09.0 should not have a PCI address
where the address is related to the guest PCI address provided.
virStringSplit may return NULL, so we must handle that.

Commit id 'c5c96545' neglected to validate that the srcPriv was
non-NULL before dereferencing. Similar problem to what was fixed
by commit id '8056721c' but missed during multiple rebases and
code reworks.
Now that we have a private storage pool list, we can take the next
step and convert to using objects. In this case, we're going to use
RWLockable objects (just like every other driver) with two hash
tables for lookup by UUID or Name.
Along the way the ForEach and Search API's will be adjusted to use
the related Hash API's and the various FindBy functions altered and
augmented to allow for HashLookup w/ and w/o the pool lock already
taken.
After virStoragePoolObjRemove we will need to virObjectUnref(obj)
after to indicate the caller is "done" with it's reference. The
Unlock occurs during the Remove.
The NumOf, GetNames, and Export functions all have their own callback
functions to return the required data and the FindDuplicate code
can use the HashSearch function callbacks.
Commit id '5ab746b8' introduced the function as perhaps a copy
of storageVolLookupByPath; however, it did not use the @cleanpath
variable even though it used the virFileSanitizePath. So in essance
the only "check" being done for failure is whether it was possible
to strdup the path.
Looking at the virStoragePoolDefParseXML one will note that the
target.path is stored using the result of virFileSanitizePath.
Therefore, this function should sanitize and use the input @path
for the argument to storagePoolLookupByTargetPathCallback which
is comparing against stored target.path values.
Additionally, if there was an error we should use the proper error
of VIR_ERR_NO_STORAGE_POOL (instead of VIR_ERR_NO_STORAGE_VOL).
Replace the error message during startup of libvirtd with an info
message if audit_level < 2 and audit is not supported by the
kernel. Audit is not supported by the current kernel if the kernel
does not have audit compiled in or if audit is disabled (e.g. by the
kernel cmdline).

When reconnecting to a running domain started by old libvirt, which did
not change host-model into a custom CPU definition, we replace the CPU
definition with a specific CPU model from host capabilities. However,
that CPU model may not be supported by the running qemu process. We need
to translate the CPU model to one of the models which libvirt could have
used when starting the domain.

Since we are re-detecting the backing chain after pivoting to the active
block commit target (or block copy target) the disk index needs to be
reset to 0. This is necessary since we move a member of the backing
chain to disk->src but clear indexes only starting from
disk->src->backingStore. The freshly detected images have indexes
starting from 1, but since we've pivoted into an image which was
previously a backing store it would have a non-0 index.
The lookup function would then return the top of the chain for queries
like 'vda[1]' instead of the first backing store.
This problem will not be present once we keep the disk indexes stable.
