Create a .snap directory mode 770 group operator in the root of
a new filesystem. Dump and fsck will create snapshots in this
directory rather than in the root for two reasons:

1) For terabyte-sized filesystems, the snapshot may require many
minutes to build. Although the filesystem will not be suspended
during most of the snapshot build, the snapshot file itself is
locked during the entire snapshot build period. Thus, if it is
accessed during the period that it is being built, the process
trying to access it will block holding its containing directory
locked. If the snapshot is in the root, the root will lock and
the system will come to a halt until the snapshot finishes. By
putting the snapshot in a subdirectory, it is out of the likely
path of any process traversing through the root and hence much
less likely to cause a lock race to the root.

2) The dump program is usually run by a non-root user running with
operator group privilege. Such a user is typically not permitted
to create files in the root of a filesystem. By having a directory
in group operator with group write access available, such a user
will be able to create a snapshot there. Having the dump program
create its snapshot in a subdirectory below the root will benefit
from point (1) as well.

Exit with a non-zero status upon a block allocation failure.
The old way of just returning could result in a file system
extremely likely to panic the kernel. The warning printed
wouldn't help much since tools invoking newfs(8), e.g., mdmfs(8),
couldn't detect the error.

When newfs'ing a partition with UFS2 that had previously been newfs'ed
with UFS1, the UFS1 superblocks were not deleted. This allowed any
RELENG_4 (or other non-UFS2-aware) fsck to think it knew how to "fix"
the file system, resulting in severe data scrambling.

This patch is a more advanced version than the one originally submitted.
Lukas improved it based on feedback from Kirk, and testing by me. It
blanks all UFS1 superblocks (if any) during a UFS2 newfs, thereby causing
fsck's that are not UFS2 aware to generate the "SEARCH FOR ALTERNATE
SUPER-BLOCK FAILED" message, and exit without damaging the fs.

Put back the error checking in wtfs() that was lost when newfs was
changed to use libufs in revision 1.71. Without this, any write
failures in newfs were silently ignored.

Note that this will display a meaningless errno string in the case
of a short write as opposed to a write error, since bwrite()'s
return value does not allow the caller to determine if errno is
valid.

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.

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).

Continue the cleanup preparations for UFS2 (& GEOM):

Use only one filedescriptor. Open in R/O or R/W based in the '-N' option.
Make the filedescriptor a global variable instead of passing it around
as semi-global variable(s).

Remove the undocumented ability to specify type without '-T' option.

Replace fatal() with straight err(3)/errx(3). Save calls to strerror()
where applicable. Loose the progname variable.

Get the sense of the cpgflag test correct so we only issue warnings if
people specify cpg and can't get that. It can be argued that this
should be an error.

Remove the check to see if the disk is mounted: Open for writing
would fail if it were mounted.

Attempt to get the sectorsize and mediasize with the generic disk
ioctls, fall back to disklabel and /etc/disktab as we can.

Notice that on-disk labels still take precedence over /etc/disktab,
this is probably wrong, but not as wrong as the entire concept of
/etc/disktab is.
