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

Use RUSAGE_SELF for the current process instead of hardcoded value

style(9) (verifed no-change in .o's)

Fix an 11 year old mistake: Let the hash functions take a void* instead
of unsigned char* argument.

In light of the recent 2^69 operation collision-finding attack on SHA1,
add support for SHA256.

Tested on: i386, sparc64
Tested using: NIST test vectors, built-in tests

fix handling of an unknown progeam name

Add sha1 and rmd160 checksum tools.

Since the algorithms are already supported in libmd,
the size increase is small when a dynamic root is used.

Set exit code to 1 in case at least one of the input files
could not be opened.

Use __FBSDID() to quiet GCC 3.3 warnings.

Improvements to md5.c so that it uses getrusage to time
benchmarks, and prints out results in float format.

Change the -x option so that it does an actual REAL test of
the correctness of this program. Previously, it printed out
the MD5 values of some test strings, but did not tell you
if they were correct or not!

Fix
md5 -q -s foo
to not expect input on stdin after hashing the string.

Add missing cast for improper time_t use in computation.

Fix include ordering breakage from rev. 1.23.

Please-read-style(9): dd

Only checksum stdin if nothing has been checksummed yet.

Include missing header files which define functions for which gcc has
builtins (e.g., exit, strcmp).

Fix argument processing.
Make this compile with WARNS=2.

Update usage().

Add -q quite mode.

Make `-r -s' also match the BSDI output.

Change the "-r" output format to match BSDI's default output format.

Add a new "-r" (right) option that reverses the order a filename and the
hash is printed. This aids visual diffs.

$Id$ -> $FreeBSD$

Since we are using strlen() let's assign it to the correct type and
include the proper header.

Fixes for -t option:

* Don't buffer "Digesting..." output - flush it immediately.
* Increase the number of repetitions by a factor of 100, and the block size by
a factor of 10 so as to give meaningful results on modern machines (108
seconds on my P120, and ~26 seconds on a P-II 350).

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Moved #include of <sys/types.h> earlier so that this compiles when
<stdio.h> doesn't (bogusly) include <sys/types.h>.

Cleaned up #includes.

Fix to match new API. Fixes memory leak, faster.

Remove trailing whitespace.

oops.

Add a '-p' option to md5. This will save some time in generation of the
ctm deltas.

Clean this file up so it is readable...
