Maintain pmap resident count as pages are mapped and unmapped instead
of traversing the page tables each time it's needed.

* Allow pv_link4_4c() to fail with ENOMEM on pool allocation failures
  (catching up with pv_link4m()).
* Fix return code checking for pv_link4m() calls.
* Add low water setting to pv pool.
