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

Core db and aristo maintenance update (#2014) * Aristo: Update error return code why: Failing of `Aristo` function `delete()` might fail because there is no such data item on the db. This must return a single error code as is done with `fetch()`. * Ledger: Better error handling why: The `expect()` clauses have been replaced by raising asserts indicating the error from the database backend. Also, `delete()` failures are legitimate if the item to delete does not exist. * Aristo: Delete function must always leave a label on DB for `hashify()` why: The `hashify()` uses the labels left bu `merge()` and `delete()` to compile (and optimise) a scheduler for subsequent hashing. Originally, the labels were not used for deleted entries and `delete()` still had some edge case where the deletion label was not properly handled. * Aristo: Update `hashify()` scheduler, remove buggy optimisation why: Was left over from version without virtual state roots which did not know about account payload leaf vertices referring to storage roots. * Aristo: Label storage trie account in `delete()` similar to `merge()` details; The `delete()` function applied to a non-static state root (assumed to be a storage root) will check the payload of an accounts leaf and mark its Merkle keys to be re-checked when runninh `hashify()` * Aristo: Clean up and re-org recycled vertex IDs in `hashify()` why: Re-organising the recycled vertex IDs list intends to reduce the size of the list. This list is organised as a LIFO (or stack.) By reorganising it in a way so that the least vertex ID numbers are on top, the list will be kept smaller as observed on some examples (less than 30%.) * CoreDb: Accept storage trie deletion requests in non-initialised state why: Due to lazy initialisation, the root vertex ID might not yet exist. So the `Aristo` database handlers would reject this call with an error and this condition needs to be handled by the API (which realises the lazy feature.) * Cosmetics & code massage, prettify logging * fix missing import
