The defaults vary by crypto library and possibly even version, so it's
not worth trying to keep them accurate.

* use 'crypto_pwhash_str_alg(..., crypto_pwhash_ALG_ARGON2ID13)' to set
  the algorithm to Argon2.
  According to libsodium's documentation, the original 'crypto_pwhash_str()'
  only guarantees a "memory-hard, CPU-intensive hash function", but not
  necessarily Argon2.  Although in released versions of libsodium Argon2 is
  the only implemented backend, this may chane in the future.
* multiply the 'memory' parameter by 1024 to align it with the libargon2
  implementation. The objective is to have consistent configuration in
  OpenLDAP's pw-argon2 module no matter what backend implementation is used.

This change implements argon2, which won the Password Hashing
Competition (https://password-hashing.net/) as a contrib-module in order
to provide a modern password hashing alternative in openldap. The
currently available password hashing algorithms are relatively old, and
modern hardware, especially GPUs can compute quite a few (ranging from
tens of thousands to millions) of hashes per second. Argon2 was designed
to withstand such attacks.

This implementation uses the default work factors used in the argon2
command line client, but the resulting hashes are stored in a way that
would allow retroactive changes to these values, or even exposing them
as configuration in the module.

    Update config.guess and config.sub from official upstream project at https://savannah.gnu.org/projects/config/

    Specifically in this case, commit 5256817ace8493502ec88501a19e4051c2e220b0 for the date Wed Jan 1 19:36:58 2020 +1100

OpenSSL removed old DES API which used des_* functions.
https://github.com/openssl/openssl/commit/24956ca00f014a917fb181a8abc39b349f3f316f



In order to link with libcrypto from recent OpenSSL releases, we need
to replace the older API des_* functions by the newer API DES_* functions.

OpenLDAP can be configured to be either built with OpenSSL or
GnuTLS. This commit adds support for building pw-pbkbdf2 module
without OpenSSL, by using PBKDF2 crypto primitives provided by
libnettle.

This updates nssov for the protocol changes in nss-pam-ldapd commits
5f55781 and 6a74d8d. The protocol was changed to network byte order,
uid_t and gid_t were changed to int32_t, and the READ_TYPE and
WRITE_TYPE macros were removed. The PAM protocol was restructured to
drop the DN field and to use a common basic set of fields for all
requests.
