65c10f6d33 Hindsight is wonderful, but I got cold feet over the crypt(3) default
so I am backing it out for now.  The problem is that some random program
calling crypt() could be passing a DES salt and the crypt(3) library
would encrypt it in md5 mode and there would be a password mismatch as a
result.  I wrote a validater function for the DES code to verify that
a salt is valid for DES, but I realized there were too many strange things
to go wrong.  passwd(1), pw(8) etc still generate md5 passwords by default
for /etc/master.passwd, so this is almost academic.  It is a big deal for
things that have their own crypt(3)-ed password strings (.htaccess,
etc etc).  Those are the things I do not want to break.

My DES salt recognizer basically checked if the salt was either 2 or
13 characters long, or began with '_' (_PASSWORD_EFMT1).  I think it
would have worked but I have seen way too much crypt() mishandling
in the past.

9886bcdf93 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.

04c9749ff0 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 :)

462da152d2 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.

3c697e0a62 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.

da5c7089a3 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.
