Nautilus is a file manager, so we should star files.
Previously we starred the content resources extracted by Tracker Miner
FS, instead. This had the advantage that the stars would follow file
renames. It had the downside of being more complex and limited in
which files can be starred. In Tracker 2.x, the feature only worked
in folders indexed by Tracker Miner FS. With Tracker 3.x, it was
additionally limited to files where Tracker had extracted metadata
-- mainly just documents and media files.
This commit takes the simpler approach of storing the star against
the file URL. All files can now be starred, and stars will no longer
persist when a file is moved or renamed.

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.
