The machine types historically have a default USB controller populated
via '-usb' which libvirt assumed implicitly. Qemu will use 'pci-ohci'
for both if '-usb' is used.
Unfortunately an USB controller instantiated via '-usb' is unusable as
the bus name libvirt generates doesn't reflect the real name qemu uses,
and thus no libvirt-defined USB devices can be put on the controller.
This patch will populate the default USB controller into the XML and
select it's model to 'pci-ohci' unconditionally as the machine would
fail to start with '-usb' if that controller model is not available.
This patch doesn't try to make any other assumptions about
auto-populated model of USB controllers, which means that for an
explicit USB controller without model a different model will be picked.
Note that this will likely cause ABI differences and break migration for
the two machine types, in the corner case when the default USB
controller would be populated, but given that both are obsolete board
types and USB was unusable it doesn't make sense to keep supporting this
specific case when '-usb' was formatted.

Rather than always binding to the vfio-pci driver, use the new
function virPCIDeviceFindBestVFIOVariant() to see if the running
kernel has a VFIO variant driver available that is a better match for
the device, and if one is found, use that instead.
virPCIDeviceFindBestVFIOVariant() function reads the modalias file for
the given device from sysfs, then looks through
/lib/modules/${kernel_release}/modules.alias for the vfio_pci alias
that matches with the least number of wildcard ('*') fields.
The appropriate "VFIO variant" driver for a device will be the PCI
driver implemented by the discovered module - these drivers are
compatible with (and provide the entire API of) the standard vfio-pci
driver, but have additional device-specific APIs that can be useful
for, e.g., saving/restoring state for migration.
If a specific driver is named (using <driver model='blah'/> in the
device XML), that will still be used rather than searching
modules.alias; this makes it possible to force binding of vfio-pci if
there is an issue with the auto-selected variant driver.

The long-deprecated use of <driver name='vfio|xen|kvm'/> in domain xml
for <hostdev> devices was only ever necessary during the period when
libvirt (and the Linux kernel) supported both VFIO and "legacy KVM"
styles of hostdev device assignment for QEMU. This became pointless
many years ago when legacy KVM device assignment was removed from the
kernel, and support for that style of device assignment was completely
disabled in the libvirt source in 2019 (commit
v5.6.0-316-g2e7225ea8c).
Nevertheless, there were instances of <driver name='vfio'/> in the
unit test data that were then (unnecessarily) propagated to several
more tests over the years. This patch cleans out those unnecessary
explicit settings of driver name='vfio' in all QEMU unit test data,
proving that the attribute is no longer (externally) needed. (A later
patch which adds a 2nd attribute to the <driver> element will include
a test case that explicitly exercises the driver name attribute).

Xen only supports a single type of PCI hostdev assignment, so it is
superfluous to have <driver name='xen'/> peppered throughout the
config. It *is* necessary to have the driver type explicitly set in
the hostdev object before calling into the hypervisor-agnostic "hostdev
manager" though (otherwise the hostdev manager doesn't know whether it
should do Xen-specific setup, or VFIO-specific setup).
Historically, the Xen driver has checked for "default" driver name
(i.e. not set in the XML), and set it to "xen', during the XML
postparse, thus guaranteeing that it will be set by the time the
object is sent to the hostdev manager at runtime, but also setting it
so early that a simple round-trip of parse-format results in the XML
always containing an explicit <driver name='xen'/>, even if that
wasn't specified in the original XML.
The QEMU driver *doesn't* set driver.name during postparse though;
instead, it waits until domain startup time (or device attach time for
hotplug), and sets the driver.name then. The result is that a
parse-format round trip of the XML in the QEMU driver *doesn't* add in
the <driver name='vfio'/>.
This patch modifies the Xen driver to behave similarly to the QEMU
driver - the PostParse just checks for a driver.name that isn't
supported by the Xen driver, and any explicit setting to "xen" is
deferred until domain runtime rather than during the postparse, thus
Xen domain XML also doesn't get extraneous <driver name='xen'/>.
This delayed setting of driver.name of course results in slightly
different xml2xml parse-format results, so the unit test data is
modified accordingly.

In order to be able to use '<interface type="network"' we need a fake
network driver in qemuxml2argvtest. Create one by simply allowing users
to reuse configs from tests/networkxml2xmlin and tests/virnetworkportxml2xmldata
which will be returned to corresponding functions.
The driver implements:
.networkLookupByName = fakeNetworkLookupByName,
- validate syntax of network name, check if config exists
.networkGetXMLDesc = fakeNetworkGetXMLDesc,
- return appropriate XML
.networkPortCreateXML = fakeNetworkPortCreateXML,
- validate that port XML exists
.networkPortGetXMLDesc = fakeNetworkPortGetXMLDesc,
- return appropriate port XML
With the above and the correspondign test data, all network XMLs can be
enabled.

Currently when we build with nbdkit support, libvirt will always try to
use nbdkit to access remote disk sources when it is available. But
without an up-to-date selinux policy allowing this, it will fail.
because the required selinux policies are not yet widely available, we
have disabled nbdkit support on rpm builds for all distributions before
Fedora 40.
Unfortunately, this makes it more difficult to test nbdkit support.
After someone updates to the necessary selinux policies, they would also
need to rebuild libvirt to enable nbdkit support. By introducing a
configure option (nbdkit_config_default), we can build packages with
nbdkit support but have it disabled by default.

DO_TEST_CPUID(arch, host, json) is a multipart test. It consists of the
following tests:
- cpuTestHostCPUID()
- cpuTestGuestCPUID(with JSON_* flag)
- cpuTestCPUIDSignature()
- DO_TEST_JSON():
- if json==JSON_MODELS:
- cpuTestGuestCPUID(without JSON_* flag)
- cpuTestJSONCPUID()
- cputestJSONSignature()
Notice that for tests with json==JSON_MODELS, cpuTestGuestCPUID() is
actually called twice but with different arguments. The first one passes
JSON_MODELS to the test function, while the second one passes 0.
The main difference in behavior when calling cpuTestGuestCPUID() with or
without the flag is that in the first case, it parses the captured qemu
output from $ARCH-cpuid-$CPU.json. It extracts the cpu model list from
that JSON, and uses that to filter out possible cpu models to match.
In other words, it tries to match the cpu to a model that was supported
by the qemu version that was used to generate this JSON file. When it
finds a match, it generates a cpu definition and compares the xml form
of that definition with the file $ARCH-cpuid-$CPU-guest.xml.
When called without the JSON_MODELS flag, it simply attempts to match it
against the full libvirt cpu map and doesn't attempt to filter out any
matches based on the JSON qemu cpu model list. After it finds a match,
it generates an xml definition for the cpu and compares it to the same
file listed above. So if these two invocations disagree on the cpu match
(e.g. because libvirt has added a cpu model to its cpu map that matches
better than one that was supported by the version of qemu that generated
the JSON file) the test will fail.
This duplicate call to cpuTestGuestCPUID() was originally added in
commit 49c945a6f5. The original
justification for that commit was to fix test failures when the Qemu
driver was disabled. But since DO_TEST_JSON() is #defined empty when
qemu is disabled, this particular invocation would not even be executed
in this scenario, so it doesn't seem relevant.

QEMU allows and in cases where you omit the not-strictly-needed 'raw'
driver on top of raw images automatically uses the protocol name inside
of the 'backing file format' field of the qcow2 image.
Libvirt expects only format names in that field.
Add example images showing this scenario, which will be fixed later.
The qcow2 image files in this commit were formatted as:
qemu-img create -f qcow2 -F nbd -b nbd+tcp://example.org:6000/blah -u qcow2-protocol-backing-nbd.qcow2 10M
and
qemu-img create -f qcow2 -F file -b raw qcow2-protocol-backing-file.qcow2
thus using 'nbd' and 'file' as backing format respectively.
(note that '-b raw' refers to the file in the example image folder)
To satisfy the test, note that the NBD image is also rejected as we
can't probe it, thus such configuration would not work.

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.

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).

While glibc provides qsort(), which usually is just a mergesort,
until sorting arrays so huge that temporary array used by
mergesort would not fit into physical memory (which in our case
is never), we are not guaranteed it'll use mergesort. The
advantage of mergesort is clear - it's stable. IOW, if we have an
array of values parsed from XML, qsort() it and produce some
output based on those values, we can then compare the output with
some expected output, line by line.
But with newer glibc this is all history. After [1], qsort() is
no longer mergesort but introsort instead, which is not stable.
This is suboptimal, because in some cases we want to preserve
order of equal items. For instance, in ebiptablesApplyNewRules(),
nwfilter rules are sorted by their priority. But if two rules
have the same priority, we want to keep them in the order they
appear in the XML. Since it's hard/needless work to identify
places where stable or unstable sorting is needed, let's just
play it safe and use stable sorting everywhere.
Fortunately, glib provides g_qsort_with_data() which indeed
implement mergesort and it's a drop in replacement for qsort(),
almost. It accepts fifth argument (pointer to opaque data), that
is passed to comparator function, which then accepts three
arguments.
We have to keep one occurance of qsort() though - in NSS module
which deliberately does not link with glib.
