Tag that imply linear object and tag that imply area object should not be used on element without explicit area=yes/no

[mkoniecz]

Currently object like this are not reported by validator. For start barrier=*, landuse=* without area=yes may be reported.

Such objects cause issues for data consumers that use osm2pgsql. It also makes interpretation of additional tags (for example name, height, width, bridge etc) complicated or impossible.
