- fix a couple of entries in struct lfs lfs_default:
- in a comment, it's called dlfs_freehd now
- dlfs_inodefmt comes after dlfs_tstamp. fortunately for this
one, LFS_44INODEFMT is also 0 so the right thing was happening.
* Extend the lfs library from fsck_lfs(8) so that it can be used with a
not-yet-existent LFS. Make newfs_lfs(8) use this library, so it can
create LFSs whose Ifile is larger than one segment.
* Make newfs_lfs(8) use strsuftoi64() for its arguments, a la newfs(8).
* Make fsck_lfs(8) respect the "file system is clean" flag.
* Don't let fsck_lfs(8) think it has dirty blocks when invoked with the
-n flag.
