[php-src] PR #23518: LDAP Object Oriented API

Pull Request: https://github.com/php/php-src/pull/23518 Author: MCMic Adding some methods to the LDAP objects to have an object oriented API. The PHP warnings are replaced by Exception throwing. Open questions and TODOs: - [ ] Add an Exception class for php-ldap insead of throwing Error. - [ ] Should the result object store the link to the ldap connection? That would allow $result->parse(… to replace ldap_parse_result($connection, $result, …. - [ ] Implement Traversable in result entries. - [ ] There is no way to get back the URI that was used to create a connection. There is ldap_get_option($conn LDAP_OPT_HOST_NAME, but it does not return the full URI. Should we store the string URI in the object and add either a getter or a public-readonly property? This property would also appear in debugInfo output, helping with debug and testing. - [ ] Write an RFC with the proposed OO API
