usr.bin: 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.

Convert to usr.bin/ to LIBADD
Reduce overlinking

Bring DPADD in sync with LDADD.

- Commit work from libprocstat project. These patches add support for runtime
file and processes information retrieval from the running kernel via sysctl
in the form of new library, libprocstat. The library also supports KVM backend
for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have
been modified to take advantage of the library (as the bonus point the fstat(1)
utility no longer need superuser privileges to operate), and the procstat(1)
utility is now able to display information from memory dumps as well.

The newly introduced fuser(1) utility also uses this library and able to operate
via sysctl and kvm backends.

The library is by no means complete (e.g. KVM backend is missing vnode name
resolution routines, and there're no manpages for the library itself) so I
plan to improve it further. I'm commiting it so it will get wider exposure
and review.

We won't be able to MFC this work as it relies on changes in HEAD, which
was introduced some time ago, that break kernel ABI. OTOH we may be able
to merge the library with KVM backend if we really need it there.

Discussed with: rwatson

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.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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

Don't depend on the modification time of the "zfs" subdir.

- Fix makefile so it doesn't break the build in some corner cases. [1]
- Remove an extra copy of zfs.c.

Flag a hack.

- Add ZFS-support to fstat(1). This allows ZFS-filsystems to be including in
the open file-listing. It is added as a separate source file, so it can
respect WITH_/WITHOUT_CDDL as compile-flags.
- The warnlevel of the Makefile was decreased to quell solaris #pragma
warnings.
- Expect that fstat(1) doesn't work with kernel compiled with
DEBUG_VFS_LOCKS/DEBUG_LOCKS for now.

Add -D_KVM_VNODE to indicate that despite being a userland program,
we want to know the vnode structures internals.

1) ANSIfy.
2) Use %p to print a pointer.
3) Use longs for fileids and ino to avoid comparing signed and unsigned.
4) Make the KVM_READ macro a little more cranky.
5) Set WARNS while I'm here.

Don't use gcc specific flags.

Removed -I${.CURDIR}/.../sys from CFLAGS.

Support more filesystems in fstat(1): now you can use fstat(1) to
find out if files on msdosfs and cd9660 filestores are open.
There was also a movement of some common things to a header, a
small cleanup.

$Id$ -> $FreeBSD$

o use getprotobynumber(3) instead of hardcoded protocol names.
Divert(4) sockets will now appear as "internet raw divert"
instead of "internet raw 254".

o -Wall tweak.
