Brian Feldman 9689d5e5ee Revamp VM map wiring.
* Allow no-fault wiring/unwiring to succeed for consistency;
  however, the wired count remains at zero, so it's a special case.

* Fix issues inside vm_map_wire() and vm_map_unwire() where the
  exact state of user wiring (one or zero) and system wiring
  (zero or more) could be confused; for example, system unwiring
  could succeed in removing a user wire, instead of being an
  error.

* Require all mappings to be unwired before they are deleted.
  When VM space is still wired upon deletion, it will be waited
  upon for the following unwire.  This makes vslock(9) work
  rather than allowing kernel-locked memory to be deleted
  out from underneath of its consumer as it would before.
