It should be detectable whether the new libldap behaves like former libldap_r.

In python-ldap all calls into libldap or libldap_r are serialized by locks in
the Python wrapper part. The locking is different if python-ldap was built
against libldap_r (locks are per connection then). So a clear distinction with
LDAP_API_VERSION would be appreciated.
