Log:
  Hide all vm/vm_pageout.h content under #ifdef _KERNEL.
  
  There are no parts useful for usermode applications in
  vm/vm_pageout.h.  Even for the specific applications like fstat and
  lsof.
  
  In my opinion, this protection is redundant and instead userspace
  should not include the header at all.  Since there are apparently
  broken third party codebases, give them a bit of slack by providing
  transitional period.
