[tracker/miner-fs-refactor: 24/127] libtracker-miner: Make TrackerMinerFS use TrackerIndexingTree

[Martyn James Russell <mr src gnome org>]

commit d0cd23e7ae14f22df0b5c9592c52d9a71ff161ca

    libtracker-miner: Make TrackerMinerFS use TrackerIndexingTree
    
    No more check-* or monitor-directory signals are emitted. Instead,
    the TrackerIndexingTree is used to determine whether files should
    be indexed.
