This adds implementations for the H_CLEAR_REF (test and clear reference bit) and H_CLEAR_MOD (test and clear changed bit) hypercalls. When clearing the reference or change bit in the guest view of the HPTE, we also have to clear it in the real HPTE so that we can detect future references or changes. When we do so, we transfer the R or C bit value to the rmap entry for the underlying host page so that kvm_age_hva_hv(), kvm_test_age_hva_hv() and kvmppc_hv_get_dirty_log() know that the page has been referenced and/or changed. These hypercalls are not used by Linux guests. These implementations have been tested using a FreeBSD guest.
