Set up the /usr/tests hierarchy.

This is a MFC of the following into stable/10:
- r257097 Set up the /usr/tests hierarchy.
- r257098 Add missing WITHOUTTESTS file.
- r257100 Add a tests(7) manual page.
- r257105 Disable WITHTESTS= for now.
- r257848 Fix buildworld when WITHTESTS is enabled.
- r257850 Subsume the functionality of MKATF into MKTESTS.
- r257851 Handle the removal of the test suite when WITHOUTTESTS=yes.
- r257852 Install category Kyuafiles from their category directories.
- r258232 Install BSD.tests.mtree when MKTESTS is yes.

Note that building with WITH_TESTS is still broken at this point (and
hence why WITHOUT_TESTS is the set as the default). Subsequent pullups
will fix the remaining issues.

Stop using auth_getval() now that it always returns NULL. Instead,
hardcode the default to what it would be if we didn't hardcode it,
i.e. DES if supported and MD5 otherwise.

Build lib/ with WARNS=6 by default.

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

Merge into a single US-exportable libcrypt, which only provides
one-way hash functions for authentication purposes. There is no more
"set the libcrypt->libXXXcrypt" nightmare.
- Undo the libmd.so hack, use -D to hide the md5c.c internals.
- Remove the symlink hacks in release/Makefile
- the algorthm is set by set_crypt_format() as before. If this is
not called, it tries to heuristically figure out the hash format, and
if all else fails, it uses the optional auth.conf entry to chose the
overall default hash.
- Since source has non-hidden crypto in it there may be some issues with
having the source it in some countries, so preserve the "secure/*"
division. You can still build a des-free libcrypt library if you want
to badly enough. This should not be a problem in the US or exporting
from the US as freebsd.org had notified BXA some time ago. That makes
this stuff re-exportable by anyone.
- For consistancy, the default in absence of any other clues is md5. This
is to try and minimize POLA across buildworld where folk may suddenly
be activating des-crypt()-hash support. Since the des hash may not
always be present, it seemed sensible to make the stronger md5 algorithm
the default.
All things being equal, no functionality is lost.

How did you sneak in...

Add working and easy crypt(3)-switching. Yes, we need a whole new API
for crypt(3) by now. In any case:

Add crypt_set_format(3) + documentation to -lcrypt.
Add login_setcryptfmt(3) + documentation to -lutil.
Support for switching crypt formats in passwd(8).
Support for switching crypt formats in pw(8).

The simple synopsis is:
edit login.conf; add a passwd_format field set to "des" or "md5"; go nuts :)

Zap SHA1 password support. This will be re-implemented at a later date.

Remove -lmd. Use dlopen() and dlsym() instead for calls to the MD5* and
SHA* routines so that callers of libcrypt are not exposed to the internal
implementation.

Someone changed major numbers of the libraries from 2 to 3 for 0 (zero) reasons.
Revert the major number back to 2.

libcrypt only export one function, before the recent changes and now:
char *crypt(const char *key, const char *salt);
The prototype didn't changed. Internal representation of `char' and `char *'
didn't changed. Therefore, there is no reason to change the version number.

Somebody deleted the SONAME override causing the symlink to be expanded
at link time and the target name compiled into the binaries. ie:
everything used libscrypt or libdescrypt explicitly.

Big code cleanup. (Inspired by Brandon Gillespie). Also move as
much as possible away from secure/ to make extending easier.

$Id$ -> $FreeBSD$

Simplified using new SYMLINKS macro, mainly to test this macro. The
ifdefs are too ugly for this to be much of a simplification. The
existence tests are even uglier now. Note that the previous commit
was not submitted by me. It missed the point and just added a second
layer of unused removals.

Fixed hard-coded "libcrypt"s. The LCRYPTBASE macro mainly makes
things hard to read, but use it while we have it.

Fix symlinking. Without the -f "force" option, the wrong version

The new crypt code broke "make world". Back it out.

Rewrite of crypt library to be more modular, and addition of the
Secure Hashing Algorithm - 1 (SHA-1), along with the further
refinement of what $x$salt$hash means. With this new crypt the
following are all acceptable:

$1$
$MD5$
$SHA1$

Note: $2$ is used by OpenBSD's Blowfish, which I considered adding
as $BF$, but there is no actual need for it with SHA-1. However,
somebody wishing to add OpenBSD password support could easilly add
it in now.

There is also a malloc_crypt() available in the library now, which
behaves exactly the same as crypt(), but it uses a malloced buffer
instead of a static buffer. However, this is not standard so will
likely not be used much (at all).

Also, for those interested I did a brief speed test Pentium 166/MMX,
which shows the DES crypt to do approximately 2640 crypts a CPU second,
MD5 to do about 62 crypts a CPU second and SHA1 to do about 18 crypts
a CPU second.

the symlink is used at runtime rather than resolved at compile time.

This effectively changes the non-DES password algoritm.

If you have the "securedist" installed you will have no problems with this.
(Though you might want to consider using this password-encryption instead
of the DES-based if your system is likely to be hacked)

If you are running a -current system without the "securedist" installed:
YOU WILL NEED TO CHANGE ALL PASSWORDS !! There is no backwards mode.

Suggested procedure is:
Update your sources
cd /usr/src/lib/libcrypt
make clean
make all
make install
passwd root
<set roots new password>
change password for any other users on the system.

This algorithm is expected to be much better than the traditional DES-
based algorithm. It uses the MD5 algorithm at what it is best at, as
opposed to the DES algorithm at something it isn't good at at all. The
algorithm is designed such that it should very hard to shortcut the
calculations needed to build a dictionary, and to make partial knowledge
(Hmm, his password starts with a 'P'...) useless. Of course if somebody
breaks the MD5 algorithm this looses too.

The salt is 48 bits (8 char @ base64).
The encrypted password is 128 bits.

And I am positively delighted to say that it takes 34 msec to crypt() a
password on a Pentium/60Mhz, so building a dictionary is not really an
option for hackers at the moment.
