Minor fixes to library interface to improve POSIX.1e compliance. This

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.
