          socket_release() - release ownership of a socket to another
          object

          socket_release() is used to change ownership (and control)
          of a socket to another object.  It is useful in daemon
          objects (like inetd) which handle connection set-up and then
          transfer a connected socket to another object for further
          processing.

          Socket ownership transfer involves a handshake between the
          current owner object and the socket to which the current
          owner wishes to transfer the socket.  The handshake is
          initiated when socket_release() is called.  socket_release()
          does appropriate security/integrity checking and then calls
          the release_callback function in object ob.  This function
          is used to notify ob that socket ownership is being
          transferred to it.  It is then ob's responsibility to call
          socket_acquire() within the release callback function.  If
          socket_acquire() is called then the handshake is complete
          and socket ownership has been successfully transferred to
          ob.  ob may decline to accept responsibility for the socket
          by not calling socket_acquire(), in which case ownership
          does not change and the current socket owner must decide how
          to respond to this.

          If the socket owner is successfully transfered then
          socket_release() returns EESUCCESS.  If ob does not accept
          ownership for the socket then EESOCKNOTRLSD is returned.
          Other errors can be returned based on security violation,
          bad socket descriptor vbalues, etc.
