* vm_map_physical_memory() now sets the wiring/locking type of the area created

Browse Source 
to B_FULL_LOCK.
* vm_clone_area() now respects the source area's wiring and inherits it. This
  should fix bug #1055.
* vm_cache::type is now duplicated in vm_area::cache_type - this allows looking
  it up without having to lock a vm_cache_ref; this also solves a locking bug
  in vm_unmap_pages() in this regard.
