        Refactor Backups to turtle files support out to a
        org.freedesktop.Tracker.Backup interface.

        * data/dbus/tracker-backup.xml: Definition for the new interface.
        * data/dbus/tracker-daemon.xml: Remove Backup method.

        * src/libtracker-data/Makefile.am:
        * src/libtracker-data/tracker-data-backup.[ch]: New files, contain
        the actual saving/restoring to/from turtle files, this was spread
        before in tracker-indexer and trackerd.

        * src/tracker-indexer/tracker-indexer.c
        (tracker_indexer_restore_backup) (restore_backup_cb): Use new
        functions in libtracker-data.

        * src/trackerd/tracker-backup.[ch]: Now they contain TrackerBackup,
        the object that's going to handle petitions from DBus.
        * src/trackerd/tracker-dbus.c: Hook the new object into trackerd.
        * src/trackerd/tracker-daemon.c: Remove implementation for Backup
        method.
