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: fix use use of strcmp
strcmp only guarantee that it will return at least 1 if the string B
is greater than that of string A.

Fix some rpcgen sample file issues.

* -Sc was generating code without a return type on main.
* -Sm was generating an unusable clean target due to undefined RM.
* -Sm was generating clean target with extra preceding space.

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.

- 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.

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.

- TI-RPC is now the default again for code generation.

- As before, inetd support support is turned of per default.
Code for inetd can be made with -I.

- Support for ``transport monitors'' and the NLSPROVIDER env
variable is still there , even if their use is not clear in
non TLI stream based systems like Free-/NetBSD. It can be activated
with -P.

- There are a few corrections in rpcgen.1 and usage function to conform
to the code. Added and documented -P

- I removed the #ifdefs checks for Free-/NetBSD since we are the only
ones who use this code. MaxOS X may have the same limitations as
we have, so this code will correctly build for them.

- Generate correct cflags.
