    devname(3): Remove obsolete code that queries dev.db
    
    In the old days of static /dev, devname(3) would get the name by
    querying the /var/run/dev.db created by dev_mkdb(8).  Now that we have
    dynamic /dev provided by devfs(5), the device name is provided by the
    'kern.devname' sysctl, thus obsoleting the db query code.
    
    I've tested to verify that the db query code isn't being used now.  So
    it's safe to remove this obsolete code.  Cleanups to dev_mkdb(8) and
    related code would follow.
    
    Meanwhile, update the man page to reflect the current code.
