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.

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.

rpcgen(1): Tag crash() routine as __dead2 for static analyzers

Suggested by: Coverity
CID: 1305464
Sponsored by: EMC / Isilon Storage Division

Cleanup unnecessary semicolons from utilities we all love.

More -Wmissing-variable-declarations fixes.

In addition to adding `static' where possible:

- bin/date: Move `retval' into extern.h to make it visible to date.c.
- bin/ed: Move globally used variables into ed.h.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.
- usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.

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.

Move #ident into #if 0.

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.

Clean up. (I hope I'm doing this right.)

Update rpcgen with the one from the TI-RPC 2.3 distribution.

Note that when built for FreeBSD, this version of rpcgen assumes
backwards compatibility mode by default. This means that it will produce
ONCRPC 4.0 compatible code unless otherwise instructed, instead of the
other way around.

One incompatibility has also been worked around: this rpcgen normally
always emits an '#include <stropts.h>' directive whether you select
backwards compatibility mode or not. We don't have STREAMS, so this
behavior has been changed: now it will only emit this line if run in TI-RPC
mode.

The 'generate output files in current directory instead of the
directory where the protocol definition file lives' hack from the
original rpcgen has been preserved.

Notable new features:

- Can be used to generate RPC servers that can be launched
from port monitors such as inetd(5).

- Can generate ANSI C code.

- Can generate sample client and server top-level programs and
makefiles in addition to the usual client and server stubs.

- Can generate inline XDR routines.

Import a newer and more functional version of rpcgen.

Obtained from: the Sun TI-RPC 2.3 source distribution

Remove trailing whitespace.

Move RPC stub generator program over from 1.1.5.
