containing the userland visible thinks (i.e. ioctl definitions). Remove all (both) old ioctls, as they had a brain dead API and made keeping binary compatibility more or less impossible. Replace by several new ioctls. While there, remove any arbitrary limits (resulting from the old, broken ioctls) and allow any length of names and passwords.
