7bf6f345e0 qemu: Probe CPU models for KVM and TCG
CPU models (and especially some additional details which we will start
probing for later) differ depending on the accelerator. Thus we need to
call query-cpu-definitions in both KVM and TCG mode to get all data we
want.

Tests in tests/domaincapstest.c are temporarily switched to TCG to avoid
having to squash even more stuff into this single patch. They will all
be switched back later in separate commits.

70c7025d3b qemu: capabilities: Add support for QMP schema introspection
Allow detecting capabilities according to the qemu QMP schema. This is
necessary as sometimes the availability of certain options depends on
the presence of a field in the schema.

This patch adds support for loading the QMP schema when detecting qemu
capabilities and adds a very simple query language to allow traversing
the schema and selecting a certain element from it.

The infrastructure in this patch uses a query path to set a specific
capability flag according to the availability of the given element in
the schema.

6869428c12 qemu_capabilities: check for existence of virtio-vga
Commit 21373feb added support for primary virtio-vga device but it was
checking for virtio-gpu.  Let's check for existence of virtio-vga if we
want to use it.

Virtio video device is currently represented by three different models
*virtio-gpu-device*, *virtio-gpu-pci* and *virtio-vga*.  The first two
models are tied together and if virtio video devices is compiled in they
both exist.  However, the *virtio-vga* model doesn't have to exist on
some architectures even if the first two models exist.  So we cannot
group all three together.

34a4447bd4 qemu_capabilities: join capabilities for qxl and qxl-vga devices
This patch simplifies QEMU capabilities for QXL video device.  QEMU
exposes this device as *qxl-vga* and *qxl* and they are both the same
device with the same set of parameters, the only difference is that
*qxl-vga* includes VGA compatibility.

Based on QEMU code they are tied together so it's safe to check only for
presence of only one of them.

This patch also removes an invalid test case "video-qxl-sec-nodevice"
where there is only *qxl-vga* device and *qxl* device is not present.

41f5c2ca27 Introduce QEMU_CAPS_VIRTIO_PCI_DISABLE_LEGACY
Check whether the disable-legacy property is present on the following
devices:
  virtio-balloon-pci
  virtio-blk-pci
  virtio-scsi-pci
  virtio-serial-pci
  virtio-9p-pci
  virtio-net-pci
  virtio-rng-pci
  virtio-gpu-pci
  virtio-input-host-pci
  virtio-keyboard-pci
  virtio-mouse-pci
  virtio-tablet-pci

Assuming that if QEMU knows other virtio devices where this property
is applicable, it will have at least one of these devices.

d0e4be9d02 Introduce SMM feature
Since its release of 2.4.0 qemu is able to enable System
Management Module in the firmware, or disable it. We should
expose this capability in the XML. Unfortunately, there's no good
way to determine whether the binary we are talking to supports
it. I mean, if qemu's run with real machine type, the smm
attribute can be seen in 'qom-list /machine' output. But it's not
there when qemu's run with -M none. Therefore we're stuck with
version based check.
