Aristo cull journal related stuff (#2288)
* Remove all journal related stuff

* Refactor function names journal*() => delta*(), filter*() => delta*()

* remove `trg` fileld from `FilterRef`

why:
  Same as `kMap[$1]`

* Re-type FilterRef.src as `HashKey`

why:
  So it is directly comparable to `kMap[$1]`

* Moved `vGen[]` field from `LayerFinalRef` to `LayerDeltaRef`

why:
  Then a separate `FilterRef` type is not needed, anymore

* Rename `roFilter` field in `AristoDbRef` => `balancer`

why:
  New name more appropriate.

* Replace `FilterRef` by `LayerDeltaRef` type

why:
  This allows to avoid copying into the `balancer` (see next patch set)
  most of the time. Typically, only one instance is running on the backend
  and the `balancer` is only used as a stage before saving data.

* Refactor way how to store data persistently

why:
  Avoid useless copy when staging `top` layer for persistently saving to
  backend.

* Fix copyright header?
