Kotresh H R f2bac9f9d5 features/libgfchangelog: APIs to process history changelogs.
1. Create directories in following fashion for history API's
   usage when consumer is registered with libgfchangelog
   shared library through gf_changelog_register.
       scratch_dir/.history
       scratch_dir/.history/.current
       scratch_dir/.history/.processed
       scratch_dir/.history/.processing

2. Added new file 'gf-history-changelog.c' and following APIs
   are provided for consumers to process history changelogs.

    1. gf_history_changelog_scan:
            Move processed history changelog file from
            .processing to .processed
    2. gf_history_changelog_next_change:
            Return the next history changelog file entry.
            Zero means all history chanelogs are consumed.
    3. gf_history_changelog_done:
            Scan .processing directory and generate a list of
            change entries.
    4. gf_history_changelog_start_fresh:
            For a set of changelogs, start from the begining.

NOTE: Though this patch provides above funcationalities.
      It is considered functionally full with the
      patch (http://review.gluster.org/#/c/6930/).
