adding railway=disused additionally to disused:railway=* ensures
backward compatibility, so that renderers which do not consider
lifecycle prefixes still produce good results.
It might also be easier for some renderers just to look at the value of
railway=* than using rendering rules like "if there is a
disused:railway=* tag then render a disused track, if there is an
abandoned:railway=* tag, ... otherwise render the value of railway".
This tagging is redundant and not necessary for using lifecycle
prefixes, but at the moment it seems to be a good compromise.
