[epiphany/history-rewrite] ephy-history-service: add 'visit-url' signal

    ephy-history-service: add 'visit-url' signal
    
    Similar to the old EphyHistory 'add-page' signal. It allows blocking
    the visit by handling the signal, since the actual logic to add the
    visit is in the class' default handler.
    
    The add_visit(s) methods won't emit this signal, but for now we'll
    assume that whoever is using those knows what he's doing.
