Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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.
