The configuration of a defined mdev can be modified after the mdev is
started. The defined configuration and the active configuration can
therefore run out of sync. Handle this by storing the modifiable data
which is the mdev type and attributes in two separate active and
defined configurations. mdevctl supports with callout scripts to do an
attribute retrieval of started mdevs which is already implemented in
libvirt.

fail, yet it was produced in real life (at least the NVDIMM

The existing capabilities were generated against a build made
quite early in the QEMU 8.1.0 development cycle. Update them
to match the final release.
A notable effect of this is that the recently introduced
s390-usb-model test now passes instead of failing: QEMU 8.1.0
enables several new devices on s390x, including the qemu-xhci
USB controller.
There's a small amount of additional churn caused by the fact
that the machine on which I have generated these capabilities
is apparently slightly less fancy than the one used originally.

The capability is asserted when both block-stream and block-commit QMP
commands support the 'backing-mask-protocol' argument.
The argument causes qemu to record 'raw' as the backing file format in
case when a protocol node is used directly. This is needed to preserve
compatibility of images after a block-commit or block-pull libvirt
operation with older libvirt versions in case when we'll want to remove
the unneded 'raw' format drivers from the block graph.

It validates that the output '.replies' files conform to how we generate

The main advantage is that JSON objects are parsed into native python
types and thus the programatic modification is much more convenient.

handle the whole of QMP schema as well as help in reviewing the

* it explicitly enables a number of devices.
Add several test cases, one for each of the architectures and
machine types that we have good support for.
Unlike the existing one, they're *really* minimal: no devices
or controllers at all are present in the input XML. So the new
test cases demonstrate exactly what devices and controller
libvirt will decide to add automatically.

The way this is currently implemented is ad-hoc, and involves
symlinking the input XML as well as coming up with an

-abi-update suffix is added, but since this is not enforced
there are a couple of cases where we do something else instead.
