Allow userland to initialize CR0 when resetting a VCPU instead of
hardcoding it. Be careful to obey VMX's must-be-0 and must-be-1
restrictions for CR0.
This gives us the opportunity later to start VCPUs in real-mode, etc.
(for those CPUs that support unrestricted guest).
Be sure to update your vmd(8) also, the ioctl interface has
changed.
ok mlarkin@, deraadt@
