Some of our scripts are known to work both with Python 2 and
Python 3, so for them we shouldn't be forcing any specific
version of the interpreter when they're called directly; we
always use $(PYTHON) explicitly in our build rules anyway.

Commit b4c2ac8d56 made a false assumption that IOMMU support necessary
for an mdev device to be assigned to a VM. Unlike direct PCI assignment,
IOMMU support is not needed for mediated devices, as the physical parent
device provides the isolation, therefore, simply checking for VFIO
presence is enough to successfully start a VM.
Luckily, this issue is not serious, since as of yet, libvirt mandates
mdevs to be pre-created prior to a domain's launch - if it is,
everything does work smoothly even with IOMMU disabled, because the
parent device will ensure the iommu groups we try to access exist.
However, if there are *no* IOMMU groups yet, thus no mdev exists yet, one
would see the following error:
"unsupported configuration: Mediated host device assignment requires VFIO
support"
The error msg above is simply wrong and doesn't even reflect the IOMMU
reality, so after applying this patch one would rather see the following
error in such case instead:
"device not found: mediated device '<UUID>' not found"

What one currently gets is:
failed to read '/sys/bus/mdev/devices/<UUID>/mdev_type/device_api': No
such file or directory
This indicates that something is missing within the device's sysfs tree
which likely might be not be the case here because the device simply
doesn't exist yet. So, when creating our internal mdev obj, let's check
whether the device exists first prior to trying to verify the
user-provided model within domain XML.

libxlDomainMigrationPrepare adds the incoming domain def to the list
of domains via virDomainObjListAdd, but never adds its own ref to the
returned virDomainObj as other callers of virDomainObjListAdd do.
libxlDomainMigrationPrepareTunnel3 suffers the same discrepancy.
Change both to add a ref to the virDomainObj after a successful
virDomainObjListAdd, similar to other callers. This ensures a consistent
pattern throughout the drivers and allows using the virDomainObjEndAPI
function for cleanup.

The libxlDomainMigrateConfirm3Params API locks and ref counts the associated

libxlDomainMigrationConfirm is also used by libxlDomainMigratePerform3Params

When building command line for USB controllers we have to do more
than just put controller's alias onto the command line. QEMU has
concept of these joined USB controllers. For instance ehci and
uhci controllers need to create the same USB bus. To achieve that
the slave controller needs to refer the master controller. This
worked until we've introduced user aliases because both master
and slave had the same alias. With user aliases slave can have
different alias than master. Therefore, when generating command
line for slave we need to look up the master's alias.
