Using the 'uuid' element for ppc64 NVDIMM memory added in the
previous patch, use it in qemuBuildMemoryDeviceStr() to pass
it over to QEMU.
Another ppc64 restriction is the necessity of a mem->labelsize,
given than ppc64 only support label-area backed NVDIMMs.
Finally, we don't want ppc64 NVDIMMs to align up due to the
high risk of going beyond the end of file with a 256MiB
increment that the user didn't predict. Align it down
instead. If target size is less than the minimum of
256MiB + labelsize, error out since QEMU will error out
if we attempt to round it up to the minimum.

ppc64 NVDIMM support was implemented in QEMU by commit [1].
The support is similar to what x86 already does, aside from
an extra 'uuid' element.
This patch introduces a new optional 'uuid' element for the
NVDIMM memory model. This element behaves like the 'uuid'
element of the domain definition - if absent, we'll create
a new one, otherwise use the one provided by the XML.
The 'uuid' element is exclusive to pseries guests and are
unavailable for other architectures.
Next patch will use this new element to add NVDIMM support
for ppc64.

So far, when using the qemu:///embed driver, management
applications can't chose whether they want to register their
domains in machined or not. While having that option is certainly
desired, it will require more work. What we can do meanwhile is
to generate names that include part of hash of the root
directory. This is to ensure that if two applications using
different roots but the same domain name (and ID) start the
domain no clashing name for machined is generated.

During startup the udev node device driver impl uses a background thread
to populate the list of devices to avoid blocking the daemon startup
entirely. There is no synchronization to the public APIs, so it is
possible for an application to start calling APIs before the device
initialization is complete.
This was not a problem in the old approach where libvirtd was started
on boot, as initialization would easily complete before any APIs were
called.
With the use of socket activation, however, APIs are invoked from the
very moment the daemon starts. This is easily seen by doing a
'virsh -c nodedev:///system list'
the first time it runs it will only show one or two devices. The second
time it runs it will show all devices. The solution is to introduce a
flag and condition variable for APIs to synchronize against before
returning any data.

case of something simple, like "domain.". But it's safe to remove
it in both cases.

During the hypervisor-agnostic validation of network devices, verify
that the interface type is either "network" or "bridge", and that if
there is any <virtualport>, that it doesn't have any type associated
with it.
This needs to be done both for the parse-time validation and for
runtime validation (after a port has been acquired from any associated
network), because an interface with type='network' could have an
actual type at runtime of "hostdev" or "direct", neither of which
support isolated='true' (yet). Likewise, if an interface is
type='network', then at runtime a <virtualport> with a type that
doesn't support isolated='yes' (e.g. "openvswitch", "802.1Qbh" -
currently *none* of the available virtualport types support it)

Similar to the way that the <vlan>, <bandwidth>, and <virtualport>
elements and the trustGuestRxFilters attribute in a <network> (or in
the appropriate <portgroup> element of a <network> can be applied to a
port when it is allocated for a domain's network interface, this patch
checks for a configured value of <port isolated="yes|no"/> in
either the domain <interface> or in the network, setting isolatedPort
in the <networkport> to the first one it finds (the setting from the
domain's <interface> is preferred). This, in turn, is passed back to
the domain when a port is allocated, so that the domain will use that
setting.
(One difference from <vlan>, <bandwidth>, <virtualport>, and
trustGuestRxFilters, is that all of those can be set in a <portgroup>
so that they can be applied only to a subset of interfaces connected
to the network. This didn't really make sense for the isolated setting
due to the way that it's implemented in Linux - the BR_ISOLATED flag
will prevent traffic from passing between two ports that both have
BR_ISOLATED set, but traffic can still go between those ports and
other ports that *don't* have BR_ISOLATED. (It would be nice if all
traffic from a BR_ISOLATED port could be blocked except traffic going
to/from a designated egress port or ports, but instead the entire
feature is implemented as a single flag. Because of this, it's really
only useful if all the ports on a network are isolated, so setting it
for a subset has no practical utility.)
