  * Maintains a monotonically increasing ID that is used for uniquely identifying {@link Tab}s.  This
  * class is responsible for ensuring that Tabs created in the same process, across every
  * {@link TabModel}, are allocated a unique ID.  Note that only the browser process should be
  * generating Tab IDs to prevent collisions.
  *
  * Calling {@link TabIdManager#incrementIdCounterTo(int)} will ensure new {@link Tab}s get IDs
  * greater than or equal to the parameter passed to that method.  This should be used when doing
  * things like loading persisted {@link Tab}s from disk on process start to ensure all new
  * {@link Tab}s don't have id collision.
  *
  * TODO(dfalcantara): Tab ID generation prior to M45 is haphazard and dependent on which Activity is
  *                    started first.  Unify the ways the maximum Tab ID is set (crbug.com/502384).
