We're not using the change_outnum for withdraw tx's (and the way we were calculating it was broken as of the addition of 'multiple outputs'). This removes the change output knowhow from withdraw_tx entirely, and pushes the responsibility up to the caller to include the change output in the output set if desired. Consequently, we also remove the change output knowhow from hsmd.
