Rather than have repetitive code - create/use a couple of helpers:

    testStoragePoolObjFindInactiveByName

This will also allow for the reduction of some cleanup path logic.

Rework some of the test driver API's to remove the need to return
failure when testStoragePoolObjFindByName returns NULL rather than
going to cleanup. This removes the need for check for "if (obj)" and in
some instances the need to for a cleanup label and a local ret variable.

Add a path for UEFI VMs for AArch32 VMs, based on the path Debian is using.
libvirt is the de facto canonical location for defining where distros
should place these firmware images, so let's define this path here to try
and minimize distro fragmentation.

The call to qemuBuildDeviceAddressStr() happens no matter
what, so we can move it to the outer possible scope inside
the function.

We can also move the call to virBufferAsprintf() after all
the checks have been performed, where it makes more sense.

This patch addresses the same aspects on PPC the bug 1103314 addressed
on x86.

PCI expander bus creates multiple primary PCI busses, where each of these
busses can be assigned a specific NUMA affinity, which, on x86 is
advertised through ACPI on a per-bus basis.

For SPAPR, a PHB's NUMA affinities are assigned on a per-PHB basis, and
there is no mechanism for advertising NUMA affinities to a guest on a
per-bus basis. So, even if qemu-ppc manages to get some sort of multi-bus
topology working using PXB, there is no way to expose the affinities
of these busses to the guest. It can only be exposed on a per-PHB/per-domain
basis.

So patch enables NUMA node tag in pci-root controller on PPC.

The way to set the NUMA node is through the numa_node option of
spapr-pci-host-bridge device. However for the implicit PHB, the only way
to set the numa_node is from the -global option. The -global option applies
to all the PHBs unless explicitly specified with the option on the
respective PHB of CLI. The default PHB has the emulated devices only, so
the patch prevents setting the NUMA node for the default PHB.

Instead of going through two completely different code paths,
one of which repeats the same hardcoded bit of information
three times in rapid succession, depending on whether or not
a firmware list has been provided at configure time, just
provide a reasonable default value and remove the extra code.

There are only two acceptable places for describing enum values.
It's either:

    typedef enum {
        /* Some long description. Therefore it's placed before
         * the value. */
        VIR_ENUM_A_VAL = 1,
    } virEnumA;

or:

    typedef enum {
        VIR_ENUM_B_VAL = 1, /* Some short description */
    } virEnumB;

However, during review of a patch sent upstream I realized that
is not always the case. I went through all the public header
files and identified all the offenders. Luckily there were just
two of them.

Yes, this makes our HTML generated documentation broken, but
that's bug of the generator. Our header files shouldn't be forced
to use something we don't want to.

'numad' may return a nodeset which contains NUMA nodes without memory
for certain configurations. Since cgroups code will not be happy using
nodes without memory we need to store only numa nodes with memory in
autoNodeset.

On the other hand autoCpuset should contain cpus also for nodes which
do not have any memory.

Remove the code from qemuProcessPrepareDomain so that it won't get even
more bloated.

Decouple them by storing them in the XML separately rather than
regenerating them. This will simplify upcoming fixes.

Move the code to separate functions to avoid complicating the existing
ones with changes.

Since virBitmapSubtract is unused modify it to perform bitmap
intersection.

Commit id 'dd9b29da' added this new variable, but didn't free it in

Use virStorageSource accessors to check the file and call
virStorageFileAccess before even attempting to stat the target. This
will be helpful once we try to add network destinations for block copy,
since there will be no need to stat them.

Move the code into a separate function so that the flow of creating the
copy is more obvious and split into logical pieces.
