Subject: r18910: Change ldb_msg_add_string() to not actually add an attribute
 if the string is zero length. This allows callers to not have to worry about
 creating an invalid ldap attribute.

See extensive discussion on samba-technical list :-)
(This used to be commit 7a1db8c2a432b9ab59b29ee1bfce6c8fe8e981a2)
