This is mostly straightforward, except for a teensy-weensy
detail: usually, there's no system wide daemon running, no system
wide available socket that anybody could connect to. PipeWire
uses a per user daemon approach instead. But this in turn means,
that the socket location floats between various locations and is
derived from various environment variables (just like the actual
socket name) and thus we must pass the variables to QEMU.

QEMU gained support for PipeWire audio backend (see QEMU commit
of v8.0.0-403-gc2d3d1c294). Its configuration knobs are basically
the same as pulseaudio's, except for PA's server name. Therefore,
a lot of code is copied over from pulseadio and fixed by
s/Pulse/Pipewire/ or s/pulseaudio/pipewire/.
There's one ley difference to PA though: pipewire daemon is
usually on per user basis (just like our qemu:///session).
Therefore, introduce this 'runtimeDir' attribute, which allows
specifying path to pipewire daemon socket (useful for
qemu:///system for instance).

Differences from qemu:
* "vmx-ept-uc" (bit 8) and "vmx-ept-wb" (bit 14) are not added to
qemu's list of named features yet, but used in several qemu cpu
models never the less. Add to libvirt regardless.
* "vmx-invvpid-single-context" (bit 41) is erroneously called
"vmx-invept-single-context" in qemu. This is the name of the
feature associated with bit 25 in both libvirt and qemu.
* "vmx-invvpid-single-context-noglobals" (bit 43) is erroneously
called "vmx-invept-single-context-noglobals". Use the correct name.

As of v9.4.0-rc2~5 it is possible to specify guest address where
a virtio-mem/virtio-pmem memory device is mapped to. What that
commit forgot to introduce was a check for overlaps.
And yes, this is technically an O(n^2) algorithm, as
virDomainMemoryDefValidate() is called over each memory device
and after this, virDomainMemoryDefValidate() also iterates over
each memory device. But given there's usually only a handful of
such devices, and this runs only when parsing domain XML I guess
code readability wins over some less obvious solution.

The current message can be misleading, because it seems to suggest
that no firmware of the requested type is available on the system.
What actually happens most of the time, however, is that despite
having multiple firmwares of the right type to choose from, none
of them is suitable because of lacking some specific feature or
being incompatible with some setting that the user has explicitly
enabled.
Providing an error message that describes exactly the problem is
not feasible, since we would have to list each candidate along
with the reason why we rejected it, which would get out of hand
quickly.
As a small but hopefully helpful improvement over the current
situation, reword the error message to make it clearer that the
culprit is not necessarily the firmware type, but rather the
overall domain configuration.

It's not possible to use password-protected ssh keys directly with
libvirt because libvirt doesn't have any way to prompt a user for the
password. To accomodate password-protected key files, an administrator
can add these keys to an ssh agent and then configure the domain with
the path to the ssh-agent socket.
Note that this requires an administrator or management app to
configure the ssh-agent with an appropriate socket path and add the
necessary keys to it. In addition, it does not currently work with
selinux enabled. The ssh-agent socket would need a label that libvirt
would be allowed to access rather than unconfined_t.

Previously without modern capabilities the test was relying on a CPU
model which was not entered into a fake list of supported cpus.
With real capabilities we have to pick a CPU model which is supported by
libvirt but in some version is not supported by qemu. I've picked
EPYC-Milan, which was introduced into qemu-6.0.
This test configures a CPU which is equivalent to EPYC-Rome by disabling
features from EPYC-Milan and uses a versioned real caps test to check it
against a qemu which doesn't support EPYC-Milan.
With real capabilities though, we can also do a positive test case by
using a version whic doesh support it. I've specifically not used the
LATEST caps so that it doesn't change once capabilities are bumped.
