/* Retrieves the changes to the LDAP card and stores them in an LDAP
 * update message.
 *
 * Calling this method changes the LDAP card, it updates the
 * meta-properties (m_*) to reflect what the LDAP contents will be once
 * the update has been performed. This allows you to do multiple (successful)
 * consecutive edits on a card in a search result. If the meta-properties
 * were not updated, incorrect assuptions would be made about what object
 * classes to add, or  what attributes to clear.
 *
 * XXX: We need to take care when integrating this code with the asynchronous
 * update dialogs, as the current code in nsAbLDAPDirectory has a problem
 * when an update fails: the modified card still gets stored and shown to
 * the user instead of being discarded. There is one especially tricky case:
 * when you do an update on a card which changes its DN, you have two
 * operations (rename, then update the other attributes). If the rename
 * operation succeeds and not the update of the attributes, you are 
 * "somewhere in between" the original card and the updated card.
