The option allows someone to run domain-to-native on already existing
domain without the need of supplying their XML.  It is basically
wrapper around 'virsh dumpxml  | virsh domxml-to-native /dev/stdin'.

Allow using the new flag with virsh.

QEMU will likely report the details of it shutting down, particularly
whether the shutdown was initiated by the guest or host.  We should
forward that information along, at least for shutdown events.  Reset
has that as well, however that is not a lifecycle event and would add
extra constants that might not be used.  It can be added later on.

virt-install and virt-manager both default to explicitly setting
"io='native'" in the disk "driver" tag. virsh, however, does not and also
does not provide an option to specify that setting at all.  As a result,
disks use a different IO mechanism (the default, "threads") when attached
post-setup using virsh.  Adding this option allows users to keep disk
performance consistent for disks attached at install, and those attached
afterward.

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.

Use the new XML helpers and use virXPathString rather than hand-rolling
the code.

Reuse virshDomainGetXML and virshDomainGetXMLFromDom.

virDomainFree has it's quirks (does not like NULL pointers, resets
libvirt errors). Replace it by a virsh helper which will allow us to
centrally fix issues with it.

The syntax-check rule will prohibit new uses of virDomainFree.

Move virshLookupDomainBy, virshCommandOptDomainBy and
virshCommandOptDomainBy to the helper file. Additionally turn the
virshCommandOptDomainBy macro into a function.

Don't accumulate helpers in virsh.c

Add a simple wrapper which will allow to set the threshold for
delivering the event.

When using thin provisioning, management tools need to resize the disk
in certain cases. To avoid having them to poll disk usage introduce an
event which will be fired when a given offset of the storage is written
by the hypervisor. Together with the API which will be added later, it
will allow registering thresholds for given storage backing volumes and
this event will then notify management if the threshold is exceeded.

Add a simple virsh command handler which makes use of the new API.

All options started with underscores, but we switched them to dashes
later on, making the style consistent.  The latest addition, however,
did not respect that, so let's change that as well.  It is tempting to
just change the name instead of adding alias, especially since nobody
ever used it, which we know thanks to the fact that it didn't work.

When setting perf events, the enabled/disabled perf events are not
listed. Since we know which events were changed it's possible to
print out the values on successful set, such as :

    virsh perf Domain --enable instructions --disable cache_misses
    instructions   : enabled
    cache_misses   : disabled

Created a helper to print the messages - use the vshPrintExtra to
adhere to the --quiet|-q option being set by some script. This will
cause the get code to print nothing, but will return success/failure.

If the VM is offline virsh attempted to at least report the pinning
information for the VM. This would not work properly now that the vcpus
can be sparse. Fix it by getting the vcpu states from the XML.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1375920

Put it into a separate function so that more fallback handling can be
added without making a mess.

cmdVcpuinfo will be split in upcomming patches thus extract the common
code that formats pinning cpumaps for the vcpus.

The fallback code used if virDomainGetVcpusFlags is not supported used
wrong XPath queries and basically did not work at all. Fix them to point
to the <domain> <vcpu> element instead of <vcpus> which was not present
until lately.

I managed to space most of the code by 5 spaces instead of 4 when
orignally implementing this function.

When using
