cbd4ab4cc6 qemu: new capabilities flag pcie-root-port.hotplug
This caps flag is set when the qemu binary supports the option
"hotplug" for pcie-root-port, ioh3420 (Intel pcie-root-port) and
xio3130-downstream (Intel pcie-downstream-port). If it's available,
it's possible to disable hotplugging/unplugging devices on a
particular port by adding ",hotplug=off" to the qemu device
commandline. This option first appears in qemu-5.0.0.

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.

6f6401fbae qemu: Probe host CPU after capabilities
The way we call query-cpu-model-expansion will rely on some capabilities
bits. Let's make sure all capabilities are set before probing host CPU.

0d254bce4e qemu: Probe for "unavailable-features" CPU property
It is similar to "filtered-features" property, which reports CPUID bits
corresponding to disabled features, but more general. The
"unavailable-features" property supports both CPUID and MSR features by
listing their names.

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.

7dfee399a8 tests: qemucaps: Bump capability test data for qemu-4.0 release on x86_64
Capture and update the 4.0.0 qemu version replies now that it was
released. I opted to keep the CPU differences as there was a qemu bug
which reported an empty string in CPU caps.

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.
