PTY_REQUEST_DESTROY to the helper process.
(make_logout_notice): New arguments helper_fd and helper_ref.
(spawn_parent): Pass helper_fd and helper_ref to
make_logout_notice.
(spawn_child): New arguments helper_fd and helper_ref. Send a
PTY_REQUEST_LOGIN to the helper process.

pty, set ignored_error = EIO on the read state correspondign to
stdout. If we don't have a separate stderr channel, set
channel->sources to 1, not 2.
