    vfs_synth - rewrite
    
    * Rewrite the whole vfs_synth mess to be compatible with devfs. Now we
      create a synthetic mountpoint and mount devfs on it. We then just
      nlookup() whatever device we need on that mountpoint.
    
    * This also fixes vinum rootmount. To use vinum as a root,
      vfs.root.mountfrom in /boot/loader.conf has to be set to
      "<fs>:vinum/vinumroot" where <fs> can be ufs or hammer.
