Core db update storage root management for sub tries (#1964)
* Aristo: Re-phrase `LayerDelta` and `LayerFinal` as object references

why:
  Avoids copying in some cases

* Fix copyright header

* Aristo: Verify `leafTie.root` function argument for `merge()` proc

why:
  Zero root will lead to inconsistent DB entry

* Aristo: Update failure condition for hash labels compiler `hashify()`

why:
  Node need not be rejected as long as links are on the schedule. In
  that case, `redo[]` is to become `wff.base[]` at a later stage.

  This amends an earlier fix, part of #1952 by also testing against
  the target nodes of the `wff.base[]` sets.

* Aristo: Add storage root glue record to `hashify()` schedule

why:
  An account leaf node might refer to a non-resolvable storage root ID.
  Storage root node chains will end up at the storage root. So the link
  `storage-root->account-leaf` needs an extra item in the schedule.

* Aristo: fix error code returned by `fetchPayload()`

details:
  Final error code is implied by the error code form the `hikeUp()`
  function.

* CoreDb: Discard `createOk` argument in API `getRoot()` function

why:
  Not needed for the legacy DB. For the `Arsto` DB, a lazy approach is
  implemented where a stprage root node is created on-the-fly.

* CoreDb: Prevent `$$` logging in some cases

why:
  Logging the function `$$` is not useful when it is used for internal
  use, i.e. retrieving an an error text for logging.

* CoreDb: Add `tryHashFn()` to API for pretty printing

why:
  Pretty printing must not change the hashification status for the
  `Aristo` DB. So there is an independent API wrapper for getting the
  node hash which never updated the hashes.

* CoreDb: Discard `update` argument in API `hash()` function

why:
  When calling the API function `hash()`, the latest state is always
  wanted. For a version that uses the current state as-is without checking,
  the function `tryHash()` was added to the backend.

* CoreDb: Update opaque vertex ID objects for the `Aristo` backend

why:
  For `Aristo`, vID objects encapsulate a numeric `VertexID`
  referencing a vertex (rather than a node hash as used on the
  legacy backend.) For storage sub-tries, there might be no initial
  vertex known when the descriptor is created. So opaque vertex ID
  objects are supported without a valid `VertexID` which will be
  initalised on-the-fly when the first item is merged.

* CoreDb: Add pretty printer for opaque vertex ID objects

* Cosmetics, printing profiling data

* CoreDb: Fix segfault in `Aristo` backend when creating MPT descriptor

why:
  Missing initialisation  error

* CoreDb: Allow MPT to inherit shared context on `Aristo` backend

why:
  Creates descriptors with different storage roots for the same
  shared `Aristo` DB descriptor.

* Cosmetics, update diagnostic message items for `Aristo` backend

* Fix Copyright year
