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.

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.

Now that qemu 4.1 was released we can update the capabilities to the
final form.

Update the capabilities from a non-upstream version (9c70209b63 is not
in qemu.git) to qemu upstream commit 33d6099906 (2019/06/18) so that we
get the QMP schema 'features' field support and are able to detect that
the 'file' block backend supports dynamic auto-read-only.
Note that I've rebuilt this on a machine with a more modern kernel and
microcode which exposes e.g. the recent CPU bug mitigations, thus I
opted to keep the CPU changes rather than trying to do a franken-caps
by updating only the output of query-qmp-schema.

We used type=full expansion on the result of previous type=static
expansion to get all possible spellings of CPU features. Since we can
now translate the QEMU's canonical names to our names, we can drop this
magic and do only type=static CPU model expansion.

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.

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.
