I don't know yet if want this feature on by default, so for now I'm
just adding support for "-cpu ...,+kvm_pv_unhalt".

Since there's linux-headers updates involved I can't take it through my
qom-cpu queue. If Paolo can tweak the subject to "target-i386: Add
paravirt CPU feature kvm_pv_unhalt" or so I'd be happy for this to go
through his uq/master queue. (qemu-kvm no longer exists, all QEMU
patches are about QEMU anyway and there's no discrete "paravirt"
subsystem or precedent in qemu.git history.)

Patch itself is
