In 3704b9003 ("tests: Add CPU detection tests"), a macro called
DO_TEST_CPUID_JSON is added. But it took only two arguments when QEMU
or YAJL is not set.
Fix it by adding a third argument. Shouldn't have any effect because
that macro compiles to nothing.

The actual CPU model in the data files is Penryn which makes the file
name look rather strange. Well, one of them contains Nehalem, but that's
a bug which will be fixed soon.

So far we only test CPUID -> CPU def conversion on artificial CPUID data
computed from another CPU def. This patch adds the infrastructure to
test this conversion on real data gathered from a host CPU and two
helper scripts for adding new test data:
- cpu-gather.sh runs cpuid tool and qemu-system-x86_64 to get CPUID data
from the host CPU; this is what users can be asked to run if they run
into an issue with host CPU detection in libvirt
- cpu-parse.sh takes the data generated by cpu-gather.sh and creates
data files for CPU detection tests
The CPUID data queried from QEMU will eventually switch to the format
used by query-host-cpu QMP command once QEMU implements it. Until then
we just spawn QEMU with -cpu host and query the guest CPU in QOM. They
should both provide the same CPUID results, but query-host-cpu does not
require any guest CPU to be created by QEMU.

The upcoming commits will make heavy modifications to the ppc64
driver, split so that it's easier to review the changes.
Instead of updating the test cases so that they pass, possibly
only to update them again with the following commit, disable them
for the time being.
Another commit will update them all in one go once all required
changes are in place.
Limitations of the POWER architecture mean that you can't run
eg. a POWER7 guest on a POWER8 host when using KVM. This applies
to all guests, not just those using VIR_CPU_MATCH_STRICT in the
CPU definition; in fact, exact and strict CPU matching are
basically the same on ppc64.
This means, of course, that hosts using different CPUs have to be
considered incompatible as well.
Change ppc64Compute(), called by cpuGuestData(), to reflect this
fact and update test cases accordingly.

A test is considered successful if the obtained result matches
the expected result: if that's not the case, whether because a
test that was expected to succeed failed or because a test that
was supposed to fail succeeded, then something's not right and
we want the user to know about this.
On the other hand, if a failure that's unrelated to the bits
we're testing occurs, then the user should be notified even if
the test was expected to fail.
Use different values to tell these two situations apart.
Fix a test case that was wrongly expected to fail as well.
QEMU 2.3 adds these new models to cover Haswell and Broadwell CPUs with
updated microcode. Luckily, they also reverted former the machine type
specific changes to existing models. And since these changes were never
released, we don't need to hack around them in libvirt.

For historical reasons data regarding NUMA configuration were split
between the CPU definition and numatune. We cannot do anything about the
XML still being split, but we certainly can at least store the relevant
data in one place.
This patch moves the NUMA stuff to the right place.
The virCPUDefFormat* methods were relying on the VIR_DOMAIN_XML_*
flag definitions. It is not desirable for low level internal
functions to be coupled to flags for the public API, since they
may need to be called from several different contexts where the
flags would not be appropriate.
Commit fba6bc4 introduced support for the 'invtsc' feature,
which blocks migration. We should not include it in the
host-model CPU by default, because it's intended to be used
with migration.
