1554eafbe6 qemu: Don't assign alias to disabled balloon device
<memballoon model='none'/> is the only way to disable balloon driver
since libvirt will add one automatically if the memballoon element is
missing. In other words, there's no balloon device if model is 'none'
and generating an alias for it makes no sense. The alias will be ignored
when parsing the XML and it will disappear once libvirtd is restarted.

13d216617d qemu: Fetch/save the default SCSI controller model during hotplug
If we're going to add a controller to the domain, let's set the
default SCSI model value if we cannot find another SCSI controller
already present.

NB: Requires updating the live output test data since the model
will now be formatted.

7c7ec17738 tests: Drop IDE controller in CCW
Adding an IDE controller for a machinetype that has no built-in IDE
controller, libvirt will log an error. Currently the machinetype list
which returns by qemuDomainMachineHasBuiltinIDE only includes 440fx,
malta, sun4u and g3beige.

adcc31bb89 qemu: domain: Fix backing store terminator for non-backing local files
Raw local files do not pass through the backing store detector and thus
the code did not allocate the required backing store terminator for
them. Previously the terminating element would be formatted into the XML
since the default values used for the metadata allowed that. This is a
regression since a693fdba01 which was not detected in the review.

This patch also reverts all the changes in the test files.

4fb8ff9987 conf: Drop virDomainChrDeviceType.targetTypeAttr
This attribute was used to decide whether to format the type
attribute of the <target> element, but the logic didn't take into
account all possible cases and as such could lead to unexpected
results. Moreover, it's one more thing to keep track of, and can
easily fall out of sync with other attributes.

Now that we have VIR_DOMAIN_CHR_SERIAL_TARGET_TYPE_NONE, we can
use that value to signal that no specific target type has been
configured for the serial device and as such the attribute should
not be formatted at all. All other values are now formatted.

19448a2561 conf: Properly parse <backingStore/>
The terminator would not be parsed properly since the XPath selector was
looking for an populated element, and also the code did not bother
assigning the terminating virStorageSourcePtr to the backingStore
property of the parent.

Some tests would catch it if there wasn't bigger fallout from the change
to backing store termination in a693fdba01. Fix them properly now.

a693fdba01 Terminate backing chains explicitly
Express a properly terminated backing chain by putting a
virStorageSource of type VIR_STORAGE_TYPE_NONE in the chain. The newly
used helpers simplify this greatly.

The change fixes a bug as formatting an incomplete backing chain and
parsing it back would end up in expressing a terminated chain since
src->backingStoreRaw was not populated. By relying on the terminator
object this can be now processed appropriately.

361c8dc179 qemu: hot-plug of watchdog
https://bugzilla.redhat.com/show_bug.cgi?id=1447169

Since domain can have at most one watchdog it simplifies things a
bit. However, since we must be able to set the watchdog action as
well, new monitor command needs to be used.

e6e26a899d tests: unify qemu binary paths for all qemu related tests
Our test data used a lot of different qemu binary paths and some
of them were based on downstream systems.

Note that there is one file where I had to add "accel=kvm" because
the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm".

ed8f236491 qemuhotplugtest: Add tests for ccw devices
There's a plan to rework the address handling, so testcases
that verify hotplugging ccw devices will help in avoiding
regression.

In this commit, some files are duplicated because of the way
qemuhotplug.c calculates the expected xml filenames.
I plan on changing that to explicitly stating the basis domain
xml, the device xml, and the expected xml.
