(ITS#7978) OpenLDAP 2.4 fails to build with LibreSSL

[spil.oss@gmail.com]

Full_Name: Bernard Spil
Version: 2.4.40
OS: FreeBSD 10.1-RC2
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (185.9.255.20)


When compiling OpenLDAP against the LibreSSL OpenSSL fork, compilation fails
because deprecated types and functions are used. These types and functions have
been marked deprecated by OpenSSL since 2002 and moved from des.h to des_old.h.
LibreSSL removed these deprecated types and functions in April 2014 see
