[tracker/wip/carlosg/domain-ontologies: 104/124] libtracker-control: Add domain argument to tracker_miner_manager_new_full

[Carlos Garnacho <carlosg src gnome org>]

commit 72e010124c19e97c432952a4ef7fecf86ad182d8
Author: Carlos Garnacho <carlosg gnome org>

    libtracker-control: Add domain argument to tracker_miner_manager_new_full
    
    I personally prefer using the excuse of the major version bump than adding
    a tracker_miner_manager_new_fuller() variant, as this is clearly a
    construct_only thing. Creating a TrackerMinerManager with an specific
    domain will allow dealing with the miners spawned for it.
