Bug 633168 - Share backend dbEnv with the replication changelog

https://bugzilla.redhat.com/show_bug.cgi?id=633168

Description:
* cl5_api.c, cl5_api.h
  - fetches dbEnv from backend using slapi_back_get_info.
  - unused macros and DB helper functions and APIs are removed.
* cl5_config.c
  - local changelog DB related config parameters are removed.
* Added SLAPI_PLUGIN_BE_PRE_CLOSE_FN and SLAPI_PLUGIN_BE_POST_OPEN_FN to
  close changelog DB before dbEnv is closed and to open changelog DB after
  dbEnv is opened, respectively.
* Added slapi APIs slapi_back_get_info and slapi_back_set_info to get/set
  the backend info.
* back-ldbm
  - db2bak[.pl] and bak2db[.pl] backs up and restores the database files
    including changelog db.
  - changelog dir is backed up in <backupdir>/.repl_changelog_backup.
  - underlying implementation ldbm_back_get_info for slapi_back_get_info
    is added.
* Added an upgrade script 81changelog.pl
