Revert r1129808:

Browse Source 
Incorporate the ap_ldap incomplete API, as there is no interest or effort
    at APR to make this a complete abstraction, and it was voted 'off the island'
    with APR 2.0.  This will allow httpd 2.3 to build against either apr-2.0
    or apr+util 1.x.

This also reverts part of r1142938, which needs to be re-done.

OpenSSL or the operating system's platform-specific SSL facilities.
Apache httpd currently does not use that apr-util interface.
modules/ldap/ provides an abstract interface for SSL encrypted LDAP
(ldaps and STARTTLS style) connections, implemented with OpenLDAP,
Netscape LDAP SDK, Mozilla LDAP SDK, or other platform specific ldap
interfaces.
Some object code distributions of Apache httpd, indicated with the
word "crypto" in the package name, may include object code for the
