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.
