Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Fix sbin/ build with a 64-bit ino_t.

Merger of the quota64 project into head.

This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).

By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:

options QUOTA # Enable FFS quotas

If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.

There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.

Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.

Drag this code kicking and screaming into the twenty-first century.

Sync up quotacheck's preen.c with fsck's. This makes quotacheck
process parallel checks in the same way as fsck, since fsck supports
pass numbers other than 0, 1 or 2. Without this, quotacheck would
ignore file systems with pass numbers > 2.

The -l (maxrun) option is now deprecated and can be tuned with pass
numbers in /etc/fstab if needed.

Quotacheck may possibly skip quota accounting for up to 2 files
on a filesystem if the quota data files reside on a different
filesystem (e.g. the userquota=/somepath,groupquota=/somepath2
options are specified in /etc/fstab to place the quota files
somewhere other than the default location).

Fix quotacheck to only skip accounting if the quota data file
actually resides on the filesystem being checked.

Flush stdout at the end of the update phase to prevent possible
duplicate output when "quotacheck -a -v" is used.

Approved by: re (bmah)

If two files systems, /a and /b are marked as having quotas enabled
in fstab and they are normally mounted as /a/b, if /b is not mounted,
the various quota utilities will incorrectly operate with the quotas on
/a (silently) when operations are attemted on /b.

Sync up all the hasquota() routines between all the different
quota utilities and change it to detect if the file system we are
attempting to perform quota operations on is not currently mounted
and warn the user accordingly.

Do not touch the block or i-node grace times for id 0.
These are used to indicate the default grace period for
the file system, and should not be touched by quotacheck.

Fix quotqcheck to correctly use the curinode count, and not the
curblock count when checking if the inode soft limit has been
crossed.

Use fseeko to seek in the file, instead of fseek to prevent seek
errors for extremely large uids (e.g. in the billions range).

Make sure that unknown uids/gids that now have non-zero usage and
had a previously recorded usage of zero are correctly displayed in
verbose mode. Generalize the print routine a little too.

Quota system cleanup.

1) Do not account for uids/gids that appear negative to prevent
the creation of 131GB+ quota files. This is the same as the kernel
now determines which files to provide quota accounting for.
Related to PR kern/38156. This should also prevent boots from
hanging if a negative uid appears in the file systems.
2) Do not count system files in the usage counts. These currently are
file system snapshot and quota data files. This is how the kernel
now handles those files.
3) Correctly generate new quota data files if the current files
do not exist or are zero length in size. PR kern/30958.
It should now be possible to newfs / mount / touch quota.{user,group}
and quotaon a file system and have everything work.
4) Change some diagnostics to report the file system and type of
id (uid or gid) that is being reported.
5) Truncate the quota data files if possible, instead of letting
them grow to a big enough size to hold the largest UID/GID on
the system (typically "nobody"). The kernel should now be able to
grow the files as needed without deadlocking the system.

Create a new 32-bit fs_flags word in the superblock. Add code to move

Leave the fs_old_flags word intact so that it will work properly if

Change the fs_sblockloc superblock location field to be in units

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).

Fix quotacheck to not do a bunch of unneeded fseeks if the
quota file information is accurate. This makes it about twice as
fast when the uid name space is very large.

Print out an informative message if the verbose option is given
and an unknown uid/gid is found in the file system. This is useful
if you wind up with a file in your file system that has a uid
that is extremely large, since quotacheck will wind up running
a very very long time due to it not handling large gaps in uids
very well (this is a problem that should be addressed some day).

Update the man page to reflect that fact the the -v flag now prints
some additional diagnostic messages.

`dev_bsize' must be reset to 1 before the bread() or
quotacheck -a will fail after the first partition (because
dev_bsize is 512 and is messes up the superblock read of the second
partition)
