18174be827 Clean up this file: 
- sync usage comment with current reality
- sort includes
- wrap lines
- use EXIT_FAILURE consistently
- make error messages consistent:  Cannot->Can't
- Remove "Old FFSv1 macros" in favor of system macros in ufs/ffs/fs.h .
  Leave dblksize() because it uses the on-disk dinode structure.

More cleanup is needed.
No functional changes intended.

6f8b62aac7 Restore a couple of checks for updating the cg_old_ncyl value which 
were commented out with XXX and a notation to "fix once fsck is fixed."
fsck seems to have been fixed for this particular issue sometime in the
7 years since the code was brought into the tree.

Update cg_old_niblk instead of cg_ni_blk, since this tool
currently supports ffsv1 only.

With these two changes, I can grow a file system and have the result
be clean according to fsck_ffs.  Shrinking still results in an unclean
file system.

OK mhitch@

While I'm here, fix a typo in an error message.

1e89108160 Add resize_ffs tool to build, change default behaviour to grow filesystem 
to device size. Add parameter -s to specify size if user want to shrink
filesystem.

Apply some KNF, remove dead unused code.

a59a9ef8db writeat() also expect offsets in DEV_BSIZE unit. This and the previous commit 
should fix PR bin/35560. Thanks to Michael L. Hitch for pointing me at the
PR.

2d9d4664a8 readat() expects the offset in DEV_BSIZE units. This made resize_ffs find the 
filesystem on a vnd partition for me. It did grow the filesystem, and after
a fsck -f on the partition to fix a few superblock inconsistencies, all
looks good.

05f998d8c6 Dunno why this code is playing 'hunt the superblock', but stop it 
finding an ffsv1 sb at 64k.
Also stop it playing with fs that have 'FS_FLAGS_UPDATED' set.
It certainly doesn't act on that falg, and my guess is that it is
playing the pre-ffsv2 fs.
Fixes part of PR kern/24809

b635f565e7 Homogenize usage messages: make the 'usage' word all lowercase, as this seems 
to be the most common practice in our tree.

ec57cc7eb3 Preliminary version of resize_ffs, based on der Mouse's fsresize tool. 
I didn't have time to clean it up completely before my legal status
w.r.t. open source projects goes into limbo for a while.  Other
developers are encouraged to play with the tool and get it into
release-worthy shape.

TODO list (see TODO file)

* verify it builds on -current, put it into release lists/etc. and src/sbin/Makefile
  (built & tested on 1.6.1)
* make it ask questions before doing any work (confirm)
* create regression test suite (see discussions on tech-kern and
  developers) and fix any bugs
* verify conversion to ANSI C didn't break anything
* port to UFS2
