adds _np to a couple of function prototypes that provided more broad/useful interfaces than POSIX.1e interfaces included. Also, move from using a heuristic to identify POSIX.1e-semantic ACLs to using different ACL types for non-POSIX.1e ACLs. This should clean up the existing fuzzy logic that determined when acl_sort() should be applied before kernel submission.
