  Log:
  Post-locking clean up/simplification, particularly, the elimination of
  vm_page_sleep_if_busy() and the page table page's busy flag as a
  synchronization mechanism on page table pages.
  
  Also, relocate the inline pmap_unwire_pte_hold() so that it can be used
  to shorten _pmap_unwire_pte_hold() on alpha and amd64.  This places
  pmap_unwire_pte_hold() next to a comment that more accurately describes
  it than _pmap_unwire_pte_hold().
