Clients can violate BufferPool invariants by calling ReservationTracker methods directly.

    Description

      If a client unpins some pages, then calls ReservationTracker::DecreaseReservation(), it can leave too many dirty unpinned pages in memory.

      Similarly, a client can cause mischief by calling AllocateFrom() and ReleaseTo() or by creating child ReservationTrackers.
