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.

The capability also represents that 'blockdev-add' is functional. It's
necessary to detect it via presence of 'blockdev-del' since blockdev-add
did not have the unsupported 'x-blockdev-add' version previously and
thus would be marked as present even if we could not use it.

Commit 766d5c1b deprecated the capability, because we were assuming
it for every QEMU binary. At the time of the introduction, there
was no way to probe for this via QMP.

However since QEMU 1.5.0 (which is the earliest version we support)
we can rely on the query-command-line-options command to detect this
feature.

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.
