Add the capabilities test data for the next qemu development cycle so
that we stay up to date.
Based on v5.2.0-1374-g9cd69f1a27
Notable changes detected by libvirt are the new machine types and
'intel-pt-lip', 'avx512-fp16', 'kvm-msi-ext-dest-id' cpu features
reported by qemu.
Other qemu changes not detected by libvirt include removal of the
'change' command, addition of 'sev-inject-launch-secret', 'yank',
'query-yank' commands and other device properties.

Due to missing pdpe1gb support in the host CPU data, the CPU is still
incorrectly detected as Westmere-IBRS for host capabilities because we

QEMU supports egl-headless if QEMU_CAPS_EGL_HEADLESS capability
is present. There are some additional requirements but those are
checked for in qemuValidateDomainDeviceDefGraphics() and depend
on domain configuration and thus are not representable in domain
capabilities. Let's stick with plain qemuCaps check then.

The feature is filtered by KVM and never automatically enabled. So even
though QEMU definition of EPYC-Rome contains this feature, the guest

domains. Thus the feature should not really be included in our
definition of EPYC-Rome.

One of the mitigation methods for TAA[1] is to disable TSX
support on the host system. Linux added a mechanism to disable
TSX globally through the kernel command line, and many Linux
distributions now default to tsx=off. This makes existing CPU
models that have HLE and RTM enabled not usable anymore.
Add new versions of all CPU models that have the HLE and RTM
features enabled, that can be used when TSX is disabled in the
host system.
On systems disabling the features without those types defined
in cpu-maps users end up without modern CPU types in the list
of usable CPUs to use in the likes of virsh domcapabilities
or tools higher in the stack like virt-manager.
This adds:
-Cascadelake-Server-noTSX
-Icelake-Client-noTSX
-Icelake-Server-noTSX
-Skylake-Server-noTSX-IBRS
-Skylake-Client-noTSX-IBRS
Introduced in QEMU by commit v4.2.0-rc2-3-g9ab2237f19 (function)

libvirt currently always reports that USB is available as a bus subsystem
type when running "virsh domcapabilities". However, this is not always
true, for example the qemu-system-s390x binary normally never has support
for USB. Thus we should only report that USB is available if there is
also a USB host controller available where we can attach USB devices.

behave.

For each QEMU version there are usually several different,
architecture-dependedn scenarios that we're interested in testing;
however, since the test matrix has to be explicitly created by
calling DO_TEST_QEMU() multiple times with different arguments, we
end up with spotty coverage.
Fix this by implementing the arch-specific rules in code, which
result in the full coverage for a (version, arch) combo being
automatically achieved with a single call to DO_TEST_QEMU().
