Previously we were only starting or stopping nbdkit when the guest was
started or stopped or when hotplugging/unplugging a disk. But when doing
block operations, the disk backing store sources can also be be added or
removed independently of the disk device. When this happens the nbdkit
backend was not being handled properly. For example, when doing a
blockcopy from a nbdkit-backed disk to a new disk and pivoting to that
new location, the nbdkit process did not get cleaned up properly. Add
some functionality to qemuDomainStorageSourceAccessModify() to handle
this scenario.
Since we're now starting nbdkit from the ChainAccessAllow/Revoke()
functions, we no longer need to explicitly start nbdkit in hotplug code
paths because the hotplug functions already call these allow/revoke
functions and will start/stop nbdkit if necessary.
Add a check to qemuNbdkitProcessStart() to report an error if we
are trying to start nbdkit for a disk source that already has a running
nbdkit process. This shouldn't happen, and if it does it indicates an
error in another part of our code.

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.

I've seen examples in the wild of the cluster attribute having
non-zero value on x86_64.
This is obviously quite confusing, but it's the information that
Linux exposes to userspace and we don't really have a way to tell
apart a valid die/cluster ID from a dummy one.
What ultimately matters is that the underlying assumptions about
topology are respected, which they are: in the x86_64 cases that
I have analyzed, for example, each "cluster" contained exactly
one core, so any program that would use this information to
influence guest topology decisions would be unaffected by the
additional level showing up in the hierarchy.
In an attempt to reduce confusion, remove any reference to any
specific value for the attributes having any special meaning
attached to it.
In fact, since there are plans to make it possible to create
guests with multiple CPU clusters on x86_64, rework the note
into a more generic warning cautioning users that an attribute
showing up here does not imply that the same attribute can be
used when defining a guest CPU topology.

Well, the latter sets an errno, so caller can just use
virReportSystemError(). And the former - it is very unlikely to
fail because memory for whole control message was allocated just
a few lines above.
The motivation is to unify behavior of virSocketSendMsgWithFDs()
and virSocketSendFD() because the latter is just a subset of the
former (will be addressed later).
