fc903aa525 Convert newfs to libufs (really). Solves one real issue with previous
version of such.  Differences in filesystems generated were found to be
from 1) sbwrite with the "all" parameter 2) removal of writecache.  The
sbwrite call was made to perform as the original version, and otherwise
this was checked against a version of newfs with the write cache removed.

41e20344a2 Add some more checks to newfs so that it will not build filesystems
that the kernel will refuse to mount. Specifically it now enforces
the MAXBSIZE blocksize limit. This update also fixes a problem where
newfs could segment fault if the selected fragment size was too large.

ada981b228 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.

1c85e6a35d 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).

9aba332745 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.

5dccd5c649 Swing the axe and remove some archaic features from newfs which modern
diskdrives do neither need nor want:

	-O create a 4.3BSD format filesystem
	-d rotational delay between contiguous blocks
	-k sector 0 skew, per track
	-l hardware sector interleave
	-n number of distinguished rotational positions
	-p spare sectors per track
	-r revolutions/minute
	-t tracks/cylinder
	-x spare sectors per cylinder

No change in the produced filesystem image unless one or more of
these options were used.

3626f83327 Update the default newfs block and fragment sizes from 8192/1024 to
16384/2048.

Following recent discussions on the -arch mailing list, involving dillon
and mckusick, this change parallels the one made over a decade ago when
the default was bumped up from 4096/512.

This should provide significant performance improvements for most
folks, less significant performance losses for a few folks and
wasted space lost to large fragments for many folks.

For discussion, please see the following thread in the -arch archive:
