Bury the declaration of the page-track helpers that are intended only for internal KVM use in a "private" header. In addition to guarding against unwanted usage of the internal-only helpers, dropping their definitions avoids exposing other structures that should be KVM-internal, e.g. for memslots. This is a baby step toward making kvm_host.h a KVM-internal header in the very distant future.
