Add missing static keywords for global variables to tools in sbin/.

These tools declare global variables without using the static keyword,
even though their use is limited to a single C-file, or without placing
an extern declaration of them in the proper header file.

The badsect(8) utility uses atol(), which doesn't allow very good error
checking and only recognizes numbers in base 10. The attached patch
checks errno after strtol() and uses a base of 0 to allow octal, or hex
sector numbers too.

Use __FBSDID() to quiet GCC 3.3 warnings.

Remove unused variable to make badsect WARNS=2 clean.

Convert badsect to use libufs.

Create a new 32-bit fs_flags word in the superblock. Add code to move
the old 8-bit fs_old_flags to the new location the first time that the
filesystem is mounted by a new kernel. One of the unused flags in
fs_old_flags is used to indicate that the flags have been moved.
Leave the fs_old_flags word intact so that it will work properly if
used on an old kernel.

Change the fs_sblockloc superblock location field to be in units
of bytes instead of in units of filesystem fragments. The old units
did not work properly when the fragment size exceeeded the superblock
size (8192). Update old fs_sblockloc values at the same time that
the flags are moved.

s/filesystem/file system/g as discussed on -developers

This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

Kill register

o Use real prototypes and ANSI function definitions.
o Remove __P.

Include missing header files which define functions for which gcc has
builtins (e.g., exit, strcmp).

Remove the block/char device distinction. badsect only worked on bdevs,
and then mapped /dev/foo into /dev/rfoo to get to the character device.
This isn't needed anymore.

Fixed printf format errors.

Correct use of .Nm. Add section number to .Xr. Add rcsid, usage(). Use err(3).

Eliminated includes of the "temporary" backwards compatibility header
<sys/dir.h> in applications. Maintained existing (inadequate) ifdefs
for dir.h vs dirent.h in libdialog, amd and rarpd, but didn't add any
new ones.

Fix all the warnings from `gcc -Wall'.

Make this actually work. It always failed in FreeBSD because it attempted
to open the mounted block device containing the directory to put the bad
sector files in, and opening of mounted block devices hasn't been allowed
since Net/2 or before. Attempt to open the raw device instead. Be more
careful about long names.

Use lstat() instead of stat() to search for block devices so that my
symlink to the default floppy doesn't cause problems.

Check for truncation of the block number when it is squeezed through the
mknod() interface. The maximum used to be only 32767, but now it large
enough.
