[tracker-miners/wip/carlosg/shuffle-libtracker-miner: 84/116] libtracker-miner: Port to G_ADD_PRIVATE



commit 8a8983d504129e84e164534941453eff8a9777a8
Author: Carlos Garnacho <carlosg gnome org>

    libtracker-miner: Port to G_ADD_PRIVATE
    
    The priv pointer has been removed from object structs for all private
    types. For public types it's got to be kept there for ABI stability.
