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/

Add HAS_TESTS to all Makefiles that are currently using the
`SUBDIR.${MK_TESTS}+= tests` idiom.

This is a follow up to r321912.

Convert traditional ${MK_TESTS} conditional idiom for including test
directories to SUBDIR.${MK_TESTS} idiom

This is being done to pave the way for future work (and homogenity) in
^/projects/make-check-sandbox .

No functional change intended.

Add some basic tests for hexdump(1)'s various output flags. Formatting
tests are omitted for this initial run as there are still some bugs to work
out there.

This covers -s flag testing on devices and non-devices that would have
caught breakage found in PR 219173 as well as other subtle breakage caused
locally.

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.

display.c:
- 'savech' is only used if it is set a few lines above where
it is used, initialize it to silence warning.

- 'length' is either -1 or greater than 0, hence it is safe to cast it
to unsigned when comparing it here.

odsyntax.c:
- 'p' is assigned either (*argvp)[0] or (*argvp)[1] which both are
char *. 'num' and 'end' are assigned values based on 'p'.
Hence use char * instead of unsigned char * for these variables.

'&end' as the second argument to strtoll does not need to be casted
to char** any more.

This solves a
'dereferencing type-punned pointer will break strict-aliasing rules'
warning when compiling with -O2.

parse.c:
- 'prec' is only used when sokay == USEPREC and sokay = USEPREC
when 'prec' is assigned. Hence 'prec' is not used uninitialized,
initialize it to silence warning.

- The code involving 'nextpr' is hard to follow, but I belive
'nextpr' will not be used unless it is initialized.
Anyway, IF 'nextpr' is used uninitialized it is better to
get a consistant error (seg fault, when dereferencing a NULL pointer)
than potentially accessing some random memory.

The above changes makes hexdump WARNS=6 clean even when compiled with
-O2. Hence bump WARNS to keep it clean.

Tested by: CFLAGS='-O2 -pipe' make universe

Revert WARNS bump until I figure out why this does not work.

Include <string.h> to get memset and strcmp prototype.

Sort includes.

This is now WARNS=2 clean, bump WARNS to keep it clean.

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

WARNS=2 fixups.

MAN[1-9] -> MAN.

Now that we've already got "hexdump -C", make calling the command "hd"
having the same effect, and install a link for this. There is
historic precedence for the command hd(1) (with roughly that output
format) in Xenix, SCO, and a few SysV's that tooks the idea.

Also, added a couple of spaces to the -C format to make the output
better readable.

Change .0 man extents to .1, as reported by Julian Elischer. Whoops,
thought I'd gotten this one the first time around.
