FWIW: Could be last patch, but that's just an ordering thing.
Considering points raised in review of other patches in this series,
extra credit to modify virsh.pod for 'vcpuinfo' (and 'domstats') to
describe the states ;-) (especially if they differ per architecture!).
Maybe there just needs to be "common" place to describe the VCPU states
much like there is a section describing the Domain States

I've got some concerns over using "halted" here considering on my
findings...
