Applied the KVM refactorings and code movement to kvm-x86 apic.

Tip tree folks, please holler if you object to any of these patches, i.e. if
you want to bikeshed some names. :-)  I've thrown these in a dedicated topic
branch, but I'll hold off on creating an "official" stable tag for a few days
to try to avoid having to carry fixups (hopefully none are needed).
