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

QEMU version >= 2.12 provides support for launching an encrypted VMs on
AMD x86 platform using Secure Encrypted Virtualization (SEV) feature.
This patch adds support to query the SEV capability from the qemu.

For getting the reply I queried the newest and oldest QEMU using
test/qemucapsprobe.  From the differences I only extracted the reply to the new
QMP command and discarded the rest.  For all the versions below the one which
added support for the new option I used the output from the oldest QEMU release
and for those that support it I used the output from the newest one.

In order to make doubly sure the reply is where it is supposed to be (the
replies files are very forgiving) I added the property to all the replies files,
reran the tests again and fixed the order in replies files so that all the
versions are reporting the new capability.  Then removed that one property.

After that I used test/qemucapsfixreplies to fix the reply IDs.

Commit 4ae59411 introduced the ability to make probing for

This commit does the last bit of work, which results in a lot

For reference, these were generated by updating a local qemu git
repository to the latest upstream, making sure the latest dependencies
were met via "dnf builddep qemu" from my sufficiently privileged root
account, checking out the v2.10.0 tag, and building in order to generate
an "x86_64-softmmu/qemu-system-x86_64" image.

Then using a clean libvirt tree updated to master and built, the image
was then provided as input:

    tests/qemucapsprobe /path/to/x86_64-softmmu/qemu-system-x86_64 > \
       tests/qemucapabilitiesdata/caps_2.10.0.x86_64.replies

With the .replies file in place and the DO_TEST line added and build,
then running the following commands:

    touch tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml
    VIR_TEST_REGENERATE_OUTPUT=1 ./tests/qemucapabilitiestest

to generate tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml and both
were added to the commit.

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.

The static CPU model expansion is designed to return only canonical
names of all CPU properties. To maintain backwards compatibility libvirt
is stuck with different spelling of some of the features, but we need to
use the full expansion to get the additional spellings. In addition to
returning all spelling variants for all properties the full expansion
will contain properties which are not guaranteed to be migration
compatible. Thus, we need to combine both expansions. First we need to
call the static expansion to limit the result to migratable properties.
Then we can use the result of the static expansion as an input to the
full expansion to get both canonical names and their aliases.

This patch simplifies QEMU capabilities for QXL video device.  QEMU
exposes this device as *qxl-vga* and *qxl* and they are both the same
device with the same set of parameters, the only difference is that
*qxl-vga* includes VGA compatibility.

Based on QEMU code they are tied together so it's safe to check only for
presence of only one of them.

This patch also removes an invalid test case "video-qxl-sec-nodevice"
where there is only *qxl-vga* device and *qxl* device is not present.

An iothread for virtio-scsi is a property of the controller. Add a lookup
of the 'virtio-scsi-pci' and 'virtio-scsi-ccw' device properties and parse
the output.  For both, support for the iothread was added in qemu 2.4
while support for virtio-scsi in general was added in qemu 1.4.

Modify the various mock capabilities replies (by hand) to reflect the
when virtio-scsi was supported and then specifically when the iothread
property was added. For versions prior to 1.4, use the no device error
return for virtio-scsi. For versions 1.4 to before 2.4, add some data
for virtio-scsi-pci even though it isn't complete we're not looking for
anything specific there anyway. For 2.4 to 2.6, add a more complete reply.
