Daniel P. Berrangé 0279a51b83 tests: fix name of 32-bit x86 QEMU binary
The 32-bit x86 binary is called qemu-system-i386, not
qemu-system-i686. This mistake across many test XML files was
not noticed because the mistake was also made in testutilsqemu.c
when mocking the capabilities.

Vitaly Kuznetsov f4c39db736 conf: qemu: add support for Hyper-V PV TLB flush
Qemu-3.0 supports Hyper-V-style PV TLB flush, Windows guests can benefit
from this feature as KVM knows which vCPUs are not currently scheduled (and
thus don't require any immediate action).

conjunction with 'hv-frequencies') can be used make Hyper-V on KVM pass
stable TSC page clocksource to L2 guests.

Vitaly Kuznetsov 8253bca961 conf: qemu: add support for Hyper-V frequency MSRs
Qemu-2.12 gained 'hv-frequencies' cpu flag to enable Hyper-V frequency
MSRs. These MSRs are required (but not sufficient) to make Hyper-V on
KVM pass stable TSC page clocksource to L2 guests.

Michal Privoznik 4d82c8fd61 test: Drop useless prefix for qemuxml2xmldata test data
There's no reason for the files to have qemuxml2xmlout- prefix
since they all live under qemuxml2xmloutdata directory.
