CPU features that always were a no-op in qemu got removed there.
We no more specify them as that would trigger errors and fail to start
qemu. This test ensures that those features really are not rendered into
qemu command line.

Qemu dropped cpu features for osxsave and ospke [1][2].
The reason for the instant removal is that those features were never
configurable as discussed in [3].
Fortunately the use cases adding those flags in the past are rare, but
they exist. One that I identified are e.g. older virt-install when used
with --cpu=host-model and there always could be the case of a user
adding it to the guest xml.
This triggers an issue like:
qemu-system-x86_64: can't apply global Broadwell-noTSX-x86_64-
cpu.osxsave=on: Property '.osxsave' not found
Ensure that this does no more break spawning newer qemu versions by
not rendering those features into the qemu command line.

vbox and vmx drivers do net case insensitive net model comparisons,
so for example 'VMXNET3' and 'vmxnet3' and 'VmxNeT3' in the XML will
translate to the same driver configuration. To convert these drivers
to use net model enum, we will need to do case insensitive comparisons
as well.
Essentially we implement virEnumToString, but with case insensitive
comparison. XML will always be formatted with the enum model string
we track internally, but we will accept any case insensitive variant.

The existing behavior for ppc64 guests is to always add a USB
keyboard and mouse combo if graphics are present; unfortunately,
this means any attempt to use a USB tablet will cause both pointing
devices to show up in the guest, which in turn will result in poor
user experience.
We can't just stop adding the USB mouse or start adding a USB tablet
instead, because existing applications and users might rely on the
current behavior; however, we can avoid adding the USB mouse if a USB
tablet is already present, thus allowing users and applications to
create guests that contain a single pointing device.
