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

It's not really useful in a jail or in a mdroot or even if a users
wants to do a full zfs machine.

Move dumpdates creation to CONFS=

Refactoring of reading and writing of the UFS/FFS superblock.
Specifically reading is done if ffs_sbget() and writing is done
in ffs_sbput(). These functions are exported to libufs via the
sbget() and sbput() functions which then used in the various
filesystem utilities. This work is in preparation for adding
subperblock check hashes.

No functional change intended.

Explicitly add more files to the 'runtime' package.

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

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.

Switch the default WARNS level for sbin/ to 6.

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

Make this WARNS=2 clean by
- using (intmax_t) and %j
- giving a non-empty format string to msg()

Include <stdint.h> directly instead of depending on <inttypes.h>
to do it.

Removed all vestiges of KerberosIV.

Fixed the MLINKS assignment style.

De-Kerberise (KerberosIV). KerberosIV is no longer present, and
remote backups can still be done with Kerberos authentication using
SSH and Kerberos 5.

Add a caching option to dump. Use -C. Note that NetBSD has a caching option
called -r but it takes 512 byte blocks instead of megabytes, and I felt a
megabytes specification would be far more useful so I did not use the same
option character.

This will *greatly* improve dump performance at the cost of possibly
missing filesystem changes that occur between passes, and does a fairly
good job making up for the loss of buffered block devices. Caching is disabled
by default to retain historical behavior.

In tests, dump performance improved by about 40% when dumping / or /usr.

Beware that dump forks and the cache may wind up being larger then you
specify, but a more complex shared memory implementation would not produce
results that are all that much better so I kept it simple for now.

Replaced exists() tests with two equivalent defined().

LIBDIR is defined in bsd.own.mk but sys.mk no longer

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

Fix for new KerberosFix for new Kerberos44

$Id$ -> $FreeBSD$

Remove useless `BINOWN=root' now that it is the default.

Fix LIBDIR (for aout/ELF).

Make this part of the 'krb' distribution.

Changes for the new KTH KerberosIV.

Implement Kerberized rcmd for rdump/rrestore. This is lacking the
options one would normally expect to set the realm, enable encryption,
and whatnot, but this actually is able to contact the remote server,
so at least it's a start. (As a bonus, the stripped static binary is
unquestionably exportable.)

Removed default setuid and added a comment to the manpage explaining this.

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.
