features/changelog : historical journal consumption.
Facilitates Glusterfs with the ability to detect file-operations happened in past by scanning the back-end(brick-level) glusterfs journal (changelog). Design: * List of changelogs produces in one perfectly running session are stored in htime file which also holds necessary information about the session start and end time. * Involves fixed sized seeks to identify N'th changelog in the list. * Requires O(log n), (where n is number of changelogs in the list), time to identify the end changelog for the given start-end time interval. Currently the background processing of changelogs is sub optimal. BZ 1097041 tracks the development effort.
