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.

Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Make lock(1) use PAM. This makes the -p option work again. (Well, kind of,
because the whole idea of this utility is rather broken.)

This originally come from NetBSD, and was later reworked a bit.

Convert to usr.bin/ to LIBADD
Reduce overlinking

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

Make WARNS=6 safe.

Tested by: make universe

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.

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

Warns cleanups:
Signal handlers are supposed to take an int as an arg.
Don't locally declare crypt or ttyname.

Set BINOWN=root explicitly for setuid root binaries.

This is not "useless", as one may have non-default
setting for BINOWN in make.conf, and we still want
these to be installed setuid root in this case.

Revert the libcrypt/libmd stuff back to how it was. This should not have
happened as it was working around problems elsewhere (ie: binutils/ld
not doing the right thing according to the ELF design). libcrypt has
been adjusted to not need the runtime -lmd. It's still not quite right
(ld is supposed to work damnit) but at least it doesn't impact all the
users of libcrypt in Marcel's cross-build model.

Add libmd (or move it after libcrypt). We don't want the linker to be
smart because it will definitely get it wrong. This popped up during
cross-linking.

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

Add dependencies on libraries to DPADD. Someday this should be done
automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.

LDADD= -lcrypt
