 * Sort the roads by name and remove duplicates.
 *
 * We want a list of roads such that every entry in the list is a different road. Since in osm
 * roads are frequently chopped into small pieces we have to remove the duplicates.
 * This doesn't have to be perfect, it needs to be useful when searching for roads.
 *
 * So we have a separate entry if the road is in a different city. This would probably be enough
 * except that associating streets with cities is not always very good in OSM. So I also create an
 * extra entry for each subdivision. Finally there a search for disconnected roads within the subdivision
 * with the same name.
 *
 * Performance note: The previous implementation was very, very slow when there were a large number
 * of roads with the same name. Although this was an unusual situation, when it happened it appears
 * that mkgmap has hung. This implementation takes a fraction of a second even for large numbers of
 * same named roads.
 *
 * @return A sorted list of road labels that identify all the different roads.
