core: rework unit name validation and manipulation logic
A variety of changes: - Make sure all our calls distuingish OOM from other errors if OOM is not the only error possible. - Be much stricter when parsing escaped paths, do not accept trailing or leading escaped slashes. - Change unit validation to take a bit mask for allowing plain names, instance names or template names or an combination thereof. - Refuse manipulating invalid unit name
