Bring in some new UVM code from NetBSD (not current).
- Introduce a new type of map that are interrupt safe and never allow faults
in them. mb_map and kmem_map are made intrsafe.
- Add "access protection" to uvm_vslock (to be passed down to uvm_fault and
later to pmap_enter).
- madvise(2) now works.
- various cleanups.
