[nautilus/sam/tracker-3: 1/5] Port to Tracker 3




commit a43727bbd121acd0fdb0439b287731b5702c62d8
Author: Sam Thursfield <sam afuera me uk>
Date:   Sat May 2 16:46:28 2020 +0200

    Port to Tracker 3
    
    Mostly the port is straightforward, we connect to tracker-miner-fs
    explicitly over D-Bus instead of the centralized tracker-store daemon
    we connected to previously.
    
    The search-engine-tracker test is now isolated from the user's real
    Tracker index using the `tracker-sandbox` script provided by Tracker,
    and it lets tracker-miner-fs index the test file rather than trying
    to synthesize the expected database contents.
    
    There are more changes in nautilus-tag-manager.c.  Until now, starred
    file information was stored in the tracker-miner-fs database. This has
    some downsides, firstly the data is deleted if someone runs `tracker
    reset --hard`, secondly it isn't possible to do this from inside a
    Flatpak sandbox with Tracker 3.0.  because the
    
    This commit changes the NautilusTagManager to set up a private
    database inside XDG_DATA_HOME/nautilus/tags. This stores the starred
    file information. The database is managed with Tracker, which allows us
    to continue using the rename-tracking that tracker-miner-fs provides.
    The same limitations apply as before that only files in indexed
    locations can be starred.
