* 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
