Add back fullname property at scan matching phase

There seems to be a lot of config files using fullname property in the world.
To keep the backward compatibility, fullname property is back to a cache at
the scan matching phase but will be rebuilt once it is done according to family
and style property in the pattern no matter what changes one made in fullname
property during that.
