Log Message:
* support uvm_pagermapin/out(), adapt uvm_pageratop()

  Instead of doing actual page remapping, which we can't portably
  do in userspace without extensive trickery (read: signals), simply
  allocate the kva window with new physical backing, copy page
  contents, return, and copy contents back in mapout.  Since the
  pages are locked during the mapping cycle, we can do this without
  hazard.

* add lots of stubbies necessary for new stuff coming soon
