It's an OpenLDAP private function, advertised in <ldap_pvt.h> and not
<ldap.h>. Unfortunately <ldap_pvt.h> is not usually installed.

This is also only declared in <ldap_pvt.h>. Maybe it belongs in <ldap.h>
instead, need to think about that.

For now, I think we can get by with explicit extern declarations in openldap.c.

I guess I should have used ldap_unbind_ext() and ldap_abandon_ext() instead.
