b4ee473578 qemucapabilitiesdata: riscv: Remove call to 'query-machines'
The riscv capabilities code doesn't use the data.

e41e3b29be qemu: Probe machine types for both KVM and TCG
Almost all TCG query-machines replies match KVM. The only exceptions are
4.2.0 replies on s390x which differ in the reported default CPU type.

124eb803fc qemu: Introduce QEMU_CAPS_MACHINE_VIRT_IOMMU
This capability can be used to figure out whether the
QEMU binary at hand supports the machine type property
we need in order to enable SMMUv3 IOMMU support.

Unfortunately we can't avoid probing the RISC-V binaries
along with the ARM ones, since both architectures have
their own 'virt' machine type.

a251095e13 qemu: Only probe available machine types
Since we know the full list of machine types supported
by the QEMU binary when probing machine type properties,
we can save some work (and eventually test suite churn,
as more architecture-specific machine types need to be
probed) by only probing machines that we know exist.

d22c6221fc qemu: Probe canonicalized machine type
Now that we have the list of machine types available when
probing machine type properties, we can list properties for
the canonicalized version of the "pseries" machine type
instead of having to go through "spapr-machine", which we
know to be the parent type for all "pseries-*-machine"
types. By doing this, we'll be able to find even properties
that are only available from a certain versioned machine
type forward, and can't thus be obtained when looking at
the parent type only.

295a42e19f qemu: Move call to virQEMUCapsProbeQMPMachineProps()
We're going to need information about available machine types
when probing machine type properties soon, and that means we
have to change the order we call QMP commands.

e67b6dcf36 qemu: capabilities: Probe caps for 'ide-hd' instead of 'ide-drive'
Since commit a4cda054e7 we are using 'ide-hd' and 'ide-cd' instead of
'ide-drive'. We also should probe capabilities for 'ide-hd' instead of
'ide-drive'. It is safe to do as 'ide-drive' is the common denominator
of both 'ide-hd' and 'ide-cd' so all the properties were common.

For now the test data are modified by just changing the appropriate type
when probing for caps.

a6fd5b596a qemu: check memory-backend-memfd.hugetlb capability
QEMU 3.1 should only expose the property if the host is actually
capable of creating hugetable-backed memfd. However, it may fail
at runtime depending on requested "hugetlbsize".

4168e33755 qemu: remove leftover property probing
Previous commits removed all capabilities from per-device property
probing for:

  pci-assign
  kvm-pci-assign
  usb-host
  scsi-generic

Remove them from the virQEMUCapsDeviceProps list and get rid of the
redundant device-list-properties QMP calls.

Note that 'pci-assign' was already useless, because the QMP version
of the device is called 'kvm-pci-assign', see libvirt commit 7257480
from 2012.
