Commit 4ae59411 introduced the ability to make probing for
device properties conditional on a capability being set, but
didn't extend the use of this feature to existing devices.

This commit does the last bit of work, which results in a lot
of pointless QMP chatter no longer happening and our test suite
shrinking a fair bit.

Add the DUMP_COMPLETED check to the capabilities. This is the
mechanism used to determine whether the dump-guest-memory command
can support the "-detach" option and thus be able to wait on the
event and allow for a query of the progress of the dump.

A microcode update can cause the CPUID bits to change; an example
from the past was the update that disabled TSX on several Haswell
and Broadwell machines.

Therefore, place microcode version in the virQEMUCaps struct and
XML, and rebuild the cache if the versions do not match.

Detect the capability via the query-qmp-schema for blockdev-add
to find the 'password-secret' parameter that will allow the iSCSI
code to use the master secret object to encrypt the secret for an

line thus obsfuscating the passphrase.

'share-rw' for the disk device configures qemu to allow concurrent
access to the backing storage.

The capability is checked in various supported disk frontend buses since
it does not make sense to partially backport it.

Up until now we assumed the spapr-vty device would always be
present, which is not very nice. Check for its availability before
using it instead.

The architecture itself is called ppc64, and it can run both in big
endian and little endian mode - the latter is known as ppc64le.

From the (virtual) hardware point of view, ppc64 is a more accurate
name so it should be used here.

The event is fired when a given block backend node (identified by the
node name) experiences a write beyond the bound set via
block-set-write-threshold QMP command. This wires up the monitor code to
extract the data and allow us receiving the events and the capability.

This unbreaks emulators that don't support this command such as
qemu-system-mips*.

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.

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.

Add the capability to detect if the qemu binary can support the feature

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.

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.

  virtio-net-pci
  virtio-rng-pci
  virtio-gpu-pci

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