Chris D. Faulhaber 0f6263079e o Separate acl_t into internal and external representations as
required by POSIX.1e.  This maintains the current 'struct acl'
  in the kernel while providing the generic external acl_t
  interface required to complete the ACL editing library.
o Add the acl_get_entry() function.
o Convert the existing ACL utilities, getfacl and setfacl, to
  fully make use of the ACL editing library.
