The default number of CPU clusters is 1, and values other than
that one are currently rejected by all hypervisor drivers.

Rather than test with synthetic capabilities which might get outdated
reuse testQemuGetRealCaps to fetch latest capabilities and use those.

Use virQEMUCapsInitQMPBasicArch in qemuHotplugCreateObjects so that we
also add the always-present capabilities to the set of capabilities used
for the hotplug test and fix fallout.

Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable
- VNC - set to "none", unless passthrough of host env variable is set
- SPICE - always set to "spice"
- SDL - always passthrough host env
- No graphics - set to "none", unless passthrough of host env variable is set
The setting of the QEMU_AUDIO_DRV env variable is done in the code which
configures graphics.
If no <audio> element is present, we now auto-populate <audio> elements
to reflect this historical default config. This avoids need to set audio
env when processing graphics.

Recently CPU hardware vendors have started to support a new structure
inside the CPU package topology known as a "die". Thus the hierarchy
is now:
sockets > dies > cores > threads
This adds support for "dies" in the XML parser, with the value
defaulting to 1 if not specified for backwards compatibility.
For example a system with 64 logical CPUs might report
<topology sockets="4" dies="2" cores="4" threads="2"/>

We do not fill out qemuCaps->arch when parsing status XML.
Use def->os.arch like we do for PPC.
This fixes hotplug after daemon restart for domains that use
a user alias for the implicit pci-root on x86.

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".

The cpu hotplug operation is rather complex so the testing code needs to
provide quite lot of data and monitor conversations to successfully test
it. The code mainly tests the selection of cpus according to the target
count request.
