faaef229b4 Add a "-b" option to search a partition for valid alternate superblocks, 
rather than searching the disk for partitions.  Also, test LFS superblock
checksums before we report them.

bebefe198b * There's no need to use an int to store the returned value of 
ffs_checkver() and later use it in the switch statement, just
  use ffs_checkver.
* Remove unneded <sys/queue.h> header.
* Remove LFS from fstypes, it was never used.
* Increase SBCOUNT to 128, works faster.
* Remove unneded casts.
* (-F mode) close fd when the scan has finished or if pread() failed.
* (-F mode) print total size of file.

6c96070844 scan_ffs(8) has been pulled up into netbsd-3 and thus will have 
"first appeared in NetBSD 3.1", not 4.0.

e9134234a3 Fold scan_lfs.8 into scan_ffs.8. It's the same program, after all.

488e14a7ad Undefine the 17 macros commonly defined by <ufs/ffs/fs.h> and 
<ufs/lfs/lfs.h> before including the second of them, and also after
including the second, to ensure the rest of the code doesn't depend
on their (ambigious) definition.

This fixes a build problem for vax; gcc 2.95.3's preprocessor
apparently doesn't like redefinition of macros.

Discussed with xtraeme.

- void casts
- remove unused notreached
- use a loop instead of code duplication
- use switches and #define constants

d191390e9e fix the date, use .An for names, correct the name (scanffs -> scan_ffs), 
.Ox/.Nx for OpenBSD/NetBSD, mention appearance in NetBSD.

disklabels.
