sbin: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

pkgbase: Put ufs related tools and lib in their own package

Add the -R option to allow fsck_ffs to restart itself when too many critical
errors have been detected in a particular run.

Clean up the global state variables so that a restart can happen correctly.

Separate the global variables in fsck_ffs and fsdb to their own file. This
fixes header sharing with fscd.

Correctly initialize, static-ize, and remove global variables as needed in
dir.c. This fixes a problem with lost+found directories that was causing
a segfault.

Correctly initialize, static-ize, and remove global variables as needed in
suj.c.

Initialize the suj globals before allocating the disk object, not after.
Also ensure that 'preen' mode doesn't conflict with 'restart' mode

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

- Merge soft-updates journaling from projects/suj/head into head. This
brings in support for an optional intent log which eliminates the need
for background fsck on unclean shutdown.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

Convert fsck_ffs to nmount(). This seems to solve
an intermittent problem where MNT_RELOAD fails

Move back to WARNS=2

Downgrade WARNS level until GCC 3.4.2 warning have been fixed.

Remove some additional paranoia which Kirk forgot to remove from his
UFS2 commit.

These bits in essence made any instance of "softupdates expected
corrution", (ie blocks marked allocated but not referenced by an
inode etc) result in a exit value for fsck_ffs of 2.

2 is part of the magic and appearantly undocumented protocol between
fsck_FOO and fsck and means "dump into single user mode ASAP.

Set the default manual section for sbin/ to 8.

Some missed magic in the fsck wrapper commit which is required by other
utilities which use bits of fsck_ffs - namely quotacheck and fsdb.
In depth, utilities.c contains blockcheck() which is needed by both,
but also a slew of routines which require bits of the FFS code to be
compiled in. This breaks the fs-specific and non-fs-specific code
up into two files (well, blockcheck() is the only routine in utilities.c,
that'll change later) which makes building fsck_ffs, quotacheck and
fsdb work yet again.

(You won't find commits to fsdb and quotacheck here before I haven't
committed the post-fsck-wrappers version of them yet.)

The beginnings of the fsck wrappers stuff from NetBSD. This particular commit
brings a newly repo-copied sbin/fsck_ffs/ (from sbin/fsck/) into fsck wrappers
mode.

A quick overview (the code reflects this):

* Documentation changed to reflect fsck_ffs instead of fsck
* Simply acts on a single filesystem, doesn't try to do any multiple filesystem
magic - this is done by the fsck wrappers now

And then specific to fsck_ffs:

* link to /sbin/fsck_4.2bsd and /sbin/fsck_ufs. This is because right now
the filesystem is of type ufs not ffs, and that during autodetection the
labeltype rather than the VFS type is used - this is because when doing
an autodetection of filesystem type in the fsck wrapper program, it does
not have any link between label type (4.2bsd, vinum, etc) and VFS string.

Note that this shouldn't break a build since the required buildworld Makefile
magic and import of the fsck wrapper code into src/sbin/fsck/ will happen
in a seperate commit.

opt_diagnostic.h isn't needed anymore.

fsdb and fsck use the ffs code which needs opt_diagnostic.h.

Merge from Lite2. Note that Lite2 has it's own filesystem clean check
skipping code that overrides ours sooner. One should be eliminated,
but for now it works.

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.
