document the libufs interface for fetching and storing inodes. The undocumented getino / putino interface has been replaced with a new getinode / putinode interface. Convert the utilities that had been using the undocumented interface to use the new documented interface. No functional change (as for now the libufs library does not do inode check-hashes).
