utilities which use bits of fsck_ffs - namely quotacheck and fsdb.
In depth, utilities.c contains blockcheck() which is needed by both,
but also a slew of routines which require bits of the FFS code to be
compiled in. This breaks the fs-specific and non-fs-specific code
up into two files (well, blockcheck() is the only routine in utilities.c,
that'll change later) which makes building fsck_ffs, quotacheck and
fsdb work yet again.
(You won't find commits to fsdb and quotacheck here before I haven't
committed the post-fsck-wrappers version of them yet.)

The beginnings of the fsck wrappers stuff from NetBSD. This particular commit
brings a newly repo-copied sbin/fsck_ffs/ (from sbin/fsck/) into fsck wrappers
mode.
A quick overview (the code reflects this):
* Documentation changed to reflect fsck_ffs instead of fsck
* Simply acts on a single filesystem, doesn't try to do any multiple filesystem
magic - this is done by the fsck wrappers now
And then specific to fsck_ffs:
* link to /sbin/fsck_4.2bsd and /sbin/fsck_ufs. This is because right now
the filesystem is of type ufs not ffs, and that during autodetection the
labeltype rather than the VFS type is used - this is because when doing
an autodetection of filesystem type in the fsck wrapper program, it does
not have any link between label type (4.2bsd, vinum, etc) and VFS string.
Note that this shouldn't break a build since the required buildworld Makefile
magic and import of the fsck wrapper code into src/sbin/fsck/ will happen
in a seperate commit.
which sets the inoinfo's i_parent and i_dotdot to 0, but they never get
set to ROOTINO. This means that propagate will never find lost+found and
its descendents, subdirectories will remain DSTATE (instead of DFOUND)
even though they *are* correctly linked in, and pass4.c will try to
clear them unsuccessfully, thinking that there is no link count from the
DSTATE directory's parent. The result is that you need to run fsck twice
and get link count increasing errors (which are unexpected and fatal
when running in preen mode). The fix is to set i_parent and i_dotdot to
"parent" after the second cacheino() call in dir.c:allocdir().

The problem turns out to be a program logic error in fsck. It stores
directory inodes internally in hash lists, using the number of
directories to form the hash key:
inpp = &inphead[inumber % numdirs];
Elsewhere, however, it increments numdirs when it finds unattached
directories. I've made the following fix, which solved the problem in
the case in hand.

superblock is invalid, fsck looks at the label to help guess where
the next superblock should be. If the partition type is 4.2BSD,
fsck assumed that the block size was valid and divided by it, so
it dumped core if the size was 0.
Initialization of the label was broken almost 3 years ago in rev.1.9
of newfs/newfs.c. Newfs does not change the label at all, so there
is no problem (except the breakage of the automatic search for
backup superblocks) unless something else sets the partition type
to 4.2BSD. However, it is too easy to set partition types to
4.2.BSD by copying an old label or by using a disktab entry to
create the label.

We now do the various superblock sanity checks that we used to do before
since it's cheap. We now get the filesystem state summary again instead
