    DEVFS - Fix xterm pty allocation, permanently fix pty permissions & ownership
    
    * Remove the hack that was put in place to support sshd and other remote
      terminal programs.
    
    * Add an override mechanic (SI_OVERRIDE) that allows the cdev to take
      over uid, gid, and perms management from the devfs_node.
    
    * Use the override mechanic in the pty code to formally set ownership and
      permissions for the pty/tty pair.
