sccs: Manual changes

For the uncommon items: Go through the tree and remove sccs tags that
didn't fit any nice pattern. If in the neighborhood, other SCM tags were
removed when they were detritis of long-ago CVS somehow in the early
mists of the project. Some adjacent copyrights stringswere removed (they
duplicated the copyright notices in the file). This also removed
non-standard formations of omission of SCCS tags (usually by adding an
extra #if 0 somewhere.

After this commit, a number of strings tagged with the 'what' @(#)
prefix remain, but they are primarily copyright notices.

minor fixup to keep things compiling. All the common forms in the tree

Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

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.

Revert most part of 200420 as requested, as more review and polish is
needed.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe

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

Use ANSI definitions.
Avoid using extern by declaring shared functions in header files.
Const poision.

Don't generate K&R C code. The -C flag is kept for backwards compatibility.
Also remove the SIG_PF macro, there is no need to cast closedown.

- Use prototypes in headers.
- Include rpc_scan.h before rpc_util.h for the tok_kind enum.
- Nuke unused declarations.

Move #ident into #if 0.

back out 1.7 changes, unneeded and possibly wrong.

Modify rpcgen -t output to something that's a lot more useful in
today's modern "no sir, not today" compilers.

Basically, when building the table:

use NULL instead of 0,
use braces around array initializers,
case the function pointers to xdrproc_t,
don't cast function pointers that do not need casting.

Removal of spaces at EOL. Add __FBSDID. New function xmalloc, xrealloc,
xstrdup. There is a crash() function that do cleaning before exiting the
program. The new functions are wrappers that make use of crash() in case
of allocation failure. warn, exit -> err.
