More sync to NetBSD.

 - Change pmap_change_wiring to pmap_unwire because it's only called that way.
 - Remove pmap_pageable because it's seldom implemented and when it is, it's
   either almost useless or incorrect. The same information is already passed
   to the pmap anyway by pmap_enter and pmap_unwire.
