The type of this parameter is virCPUType so calling it 'mode' is pretty
strange, 'type' is a much better name.

Not all async jobs are visible via virDomainGetJobStats (either they are
too fast or getting the stats is not allowed during the job), but
forcing all of them to advertise the operation is easier than hunting
the jobs for which fetching statistics is allowed. And we won't need to
think about this when we add support for getting stats for more jobs.

The parameter is reported by virDomainGetJobStats API and
VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event and it can be used to identify
the operation (migration, snapshot, ...) to which the reported
statistics belong.

As with virtio-scsi, the "internal error" messages after
preparing a vhost-scsi hostdev overwrites more meaningful
error messages deeper in the callchain. Remove it too.

I tried to attach a SCSI LUN to two different guests, and forgot
to specify "shareable" in the hostdev XML. Attaching the device
to the second guest failed, but the message was not helpful in
telling me what I was doing wrong:
$ cat scsi_scratch_disk.xml
<hostdev mode='subsystem' type='scsi'>
<source>
<adapter name='scsi_host3'/>
<address bus='0' target='15' unit='1074151456'/>
</source>
</hostdev>
$ virsh attach-device dasd_sles_d99c scsi_scratch_disk.xml
Device attached successfully
$ virsh attach-device dasd_fedora_0e1e scsi_scratch_disk.xml
error: Failed to attach device from scsi_scratch_disk.xml
error: internal error: Unable to prepare scsi hostdev: scsi_host3:0:15:1074151456
I eventually discovered my error, but thought it was weird that
Libvirt doesn't provide something more helpful in this case.
Looking over the code we had just gone through, I commented out
the "internal error" message, and got something more useful:
$ virsh attach-device dasd_fedora_0e1e scsi_scratch_disk.xml
error: Failed to attach device from scsi_scratch_disk.xml
error: Requested operation is not valid: SCSI device 3:0:15:1074151456 is already in use by other domain(s) as 'non-shareable'
Looking over the error paths here, we seem to issue better
messages deeper in the callchain so these "internal error"
messages overwrite any of them. Remove them, so that the
more detailed errors are seen.

0feebab2 adds calling qemuBlockNodeNamesDetect for completed job
on updating block jobs. This affects cancelling drive mirror logic as
this function drops vm lock. Now we have to recheck all disks
before the disk with the completed block job before going
to wait for block job events.

qemuDomainGetNumaParameters would return the automatic nodeset even for
the persistent config if the domain was running. This is incorrect since
the automatic nodeset will be re-queried upon starting the vm.

While peer-to-peer migration enters the Confirm phase even if the
Perform phase fails, the client which initiated a non-p2p migration will
never call virDomainMigrateConfirm* API if the Perform phase failed.
Thus we need to explicitly reset migration before reporting a failure
from the Perform phase API.

Migration with old QEMU which does not support query-migrate-parameters
would fail because the QMP command is called unconditionally since the
introduction of TLS migration. Previously it was only called if the user
explicitly requested a feature which uses QEMU migration parameters. And
even then the situation was not ideal, instead of reporting an
unsupported feature we'd just complain about missing QMP command.
Trivially no migration parameters are supported when
query-migrate-parameters QMP command is missing. There's no need to
report an error if it is missing, the callers will report better error
if needed.

Rather than using "ret = -1" and cleanup processing, alter the return
path on failure to goto error and then just return the data.got.
In the error path, we no longer check for ret < 0, we just can free

Instead of figuring out upfront whether <input> will be a single
or a pair element, format the subelements into a separate buffer
and close <input/> early if this buffer is empty.
There's lot more to document about the nodedev driver, besides PCI and
SR-IOV (even this might need to be extended), but let's start small-ish
and at least have a page for it linked from the drivers.html.

During 'matrix' testing of all possible combinations I found that if
device is formated with "gpt" first, then an attempt is made to format
using "mac", a startup will fail.
Deeper analysis by Peter Krempa indicates that the "mac" table fits
into the first block on the disk. Since the GPT disklabel is stored
at LBA address 1 it is not overwritten at all. Thus it's apparent that
the (blkid) detection tool then prefers GPT over a older disklabel.
The GPT disklabel has also a secondary copy at the last LBA of the disk.
So, follow the same logic as the logical pool in clearing a 1MB swath
at the beginning and end of the device to avoid potential issues with
larger sector sizes for the device.
Also fixed a minor formatting nit in virStorageBackendDeviceIsEmpty call.
Create a wrapper/helper that can be used to call the storage backend
wipe helper - storageBackendVolWipeLocalFile for future use by logical
and disk backends to clear out the partition table rather than having
each open code the same algorithm.
Add bool 'zero_end' and logic that would allow a caller to wipe specific
portions of a target device either from the beginning (the default) or
from the end when zero_end is true.
This will allow for this code to wipe out partition table information
from a device.
There were a few bugs in keycodemap tool that broke it
when run on python circa 2.7.5 or older, which affected
RHEL builds.
