Enable access to the NFSv4 acl via the NFSv4.1 'dacl' and 'sacl'
attributes.
This allows the server to authenticate the DACL and the SACL operations
separately, since reading and/or editing the SACL is usually considered
to be a privileged operation.
It also allows the propagation of automatic inheritance information that
was not supported by the NFSv4.0 'acl' attribute.
