Subject: [PATCH] Resolve several issues with the External Changelog with regards to Cookies and changes with updates and purging. More specifically these changes are resolving the following issues : OPENDJ-57 - ECL: lastChangeNumber and firstChangeNumber reset to zero when the changelog is purged to empty OPENDJ-172 - External ChangeLog Cookie varies when searching with an empty cookie. Cookie should be reproducible. OPENDJ-173 - External ChangeLog cookies content is altered by Change purging and prevents from continuing search with a previous returned cookie.
