With the request to convert bounding to actual refusal, and then
doing so in new hooks, the two previously separate patches now need
to be in a series, with infrastructure work done first. Clearly the
checking in other load handlers could (and likely wants to be) moved
to separate check handlers as well - one example of doing so is
added anew in v4, the rest will want doing down the road.

Only patch 1 changed in v5; see there for details.

1: HVM: split restore state checking from state loading
2: HVM: adjust save/restore hook registration for optional check handler
3: vPIT: check values loaded from state save record
4: vPIC: check values loaded from state save record
5: vIRQ: split PCI link load state checking from actual loading
