add initial, untested version of ldap_modify_batch

Add an initial, hitherto-untested version of ldap_modify_batch to the LDAP
module. It allows performing multiple modifications as part of a single
"transaction". This can be useful e.g. for the "change password" operation in
Active Directory (REMOVE the old unicodePwd and ADD the new one), but the
interface has been kept general.

By virtue of a copy-paste error, the constant LDAP_DEREF_ALWAYS was defined
multiple times. Now, it isn't anymore.
