Subject: Added ads_process_results(), which takes a function that is called
 for each entry returned from a search, and applies it to the results. 
 Re-structured ads_dump to use this, plus changed the ber_free in ads_dump
 from (b,1) to (b,0), in accordance with openldap manpages.  Also allows
 proper free of result using ldap_msgfree afterwards, so you can do something
 with the results after an ads_dump. (This used to be commit
 f01f02fc569b4f5101a37d3b493f2fe2d2b2677a)
