e6be524508 tests: qemucapabilities: Test commands used to query capabilities
Use qemuMonitorTestNewFromFileFull which allows to test commands used
along with providing replies. This has two advantages:

1) It's easier to see which command was used when looking at the files
2) We check that the used commands are actually in the correct order

263e65fd20 qemu: introduce vfio-ccw capability
Let us introduce the capability vfio-ccw for supporting the basic
channel I/O passthrough, which have been introduced in QEMU 2.10. The
current focus is to support dasd-eckd (cu_type/dev_type = 0x3990/0x3390)
as the target device.

Let us also introduce the capability QEMU_CAPS_CCW_CSSID_UNRESTRICTED
for virtual-css-bridge. This capability is based on the
cssid-unrestricted property which exists if QEMU no longer enforces
cssid restrictions based on ccw device types.

Vfio-ccw capability is dependent on the hidden virtual-css-bridge, so
that we are able to probe for the cssid-unrestriced property to make
sure the devices are visible to non-mcss-e enabled guests.

a68ba68330 qemu: Take full advantage of conditional device property probing
Commit 4ae59411fa 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.

91927c62d8 qemu: Check migratable host CPU features
If calling query-cpu-model-expansion on the 'host'/'max' CPU model with
'migratable' property set to false succeeds, we know QEMU is able to
tell us which features would disable migration. Thus we can mark all
enabled features as migratable.

d7f054a512 qemu: Probe "max" CPU model in TCG
Querying "host" CPU model expansion only makes sense for KVM. QEMU 2.9.0
introduces a new "max" CPU model which can be used to ask QEMU what the
best CPU it can provide to a TCG domain is.

5d513d4659 qemu-caps: Get host model directly from Qemu when available
When qmp query-cpu-model-expansion is available probe Qemu for its view of the
host model. In kvm environments this can provide a more complete view of the
host model because features supported by Qemu and Kvm can be considered.
