Make vm_fault much cleaner by removing the evil macro inlines, and
put alot of it's context into a data structure. This allows
significant shortening of its codepath, and will significantly
decrease it's cache footprint.
Also, add some stats to vmmeter. Note that you'll have to
rebuild/recompile vmstat, systat, etc... Otherwise, you'll
get "very interesting" paging stats.
