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.

05af6784b1 qemu_capabilities: mark QEMU_CAPS_VGA_QXL capability as deprecated
If QEMU in question supports QMP, this capability is set if
QEMU_CAPS_DEVICE_QXL was set based on existence of "-device qxl". If
libvirt needs to parse *help*, because there is no QMP support, it
checks for existence of "-vga qxl", but it also parses output of
"-device ?" and sets QEMU_CAPS_DEVICE_QXL too.

Now that libvirt supports only QEMU that has "-device" implemented it's
safe to drop this capability and stop using it.

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.

920bbe5c15 qemu: capabilities: Extract availability of new cpu hotplug for machine types
QEMU reports whether 'query-hotpluggable-cpus' is supported for a given
machine type. Extract and cache the information using the capability
cache.

When copying the capabilities for a new start of qemu, mask out the
presence of QEMU_CAPS_QUERY_HOTPLUGGABLE_CPUS if the machine type
doesn't support hotpluggable cpus.

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.
