/* Replication module runs when OVSDB server runs in the backup mode.
*
* API Usage
*===========
*
* - replication_set_db() needs to be called whenever database switches into
* the backup mode.
*
* - replication_remove_db() needs to be called whenever backup database
* switches into an active mode.
*
* - replication_destroy() should be called when OVSDB server shutdown to
* reclaim resources.
*
* - replication_run(), replication_wait(), replication_is_alive() and
* replication_get_last_error() should be call within the main loop
* whenever OVSDB has backup databases.
*
* - parse_excluded_tables(), get_excluded_tables() and replication_usage()
* are support functions used mainly by unixctl commands.
