Alan Cox 1b3b9cfe1d 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().
