Aristo and ledger small updates (#1888) * Fix debug noise in `hashify()` for perfectly normal situation why: Was previously considered a fixable error * Fix test sample file names why: The larger test file `goerli68161.txt.gz` is already in the local archive. So there is no need to use the smaller one from the external repo. * Activate `accounts_cache` module from `db/ledger` why: A copy of the original `accounts_cache.nim` source to be integrated into the `Ledger` module wrapper which allows to switch between different `accounts_cache` implementations unser tha same API. details: At a later state, the `db/accounts_cache.nim` wrapper will be removed so that there is only one access to that module via `db/ledger/accounts_cache.nim`. * Fix copyright headers in source code

Aristo db refactor tx paradim (#1674) * Better error handling why: Bail out on some error as early as possible before any changes. * Implement `fetch()` as opposite of `merge()` rationale: In the `Aristo` realm, the action named `fetch()` and `merge()` indicate leaf value related actions on the MPT, while actions `get()` and `put()` handle vertex or hash key related operations that constitute the MPT. * Re-factor `merge()` prototypes why: The most used variant of `merge()` should have the simplest prototype. * Persistent DB constructor needs to import `aristo/aristo_init/persistent` why: Most applications use memory DB anyway. This avoids linking `-lrocksdb` or any other back end libraries by default. * Re-factor transaction module why: Got the paradigm wrong. The transaction descriptor did replace the database one but should be handled separately.

Aristo db update for short nodes key edge cases (#1887) * Aristo: Provide key-value list signature calculator detail: Simple wrappers around `Aristo` core functionality * Update new API for `CoreDb` details: + Renamed new API functions `contains()` => `hasKey()` or `hasPath()` which disables the `in` operator on non-boolean `contains()` functions + The functions `get()` and `fetch()` always return a not-found error if there is no item, available. The new functions `getOrEmpty()` and `mergeOrEmpty()` return an an empty `Blob` if there is no such key found. * Rewrite `core_apps.nim` using new API from `CoreDb` * Use `Aristo` functionality for calculating Merkle signatures details: For debugging, the `VerifyAristoForMerkleRootCalc` can be set so that `Aristo` results will be verified against the legacy versions. * Provide general interface for Merkle signing key-value tables details: Export `Aristo` wrappers * Activate `CoreDb` tests why: Now, API seems to be stable enough for general tests. * Update `toHex()` usage why: Byteutils' `toHex()` is superior to `toSeq.mapIt(it.toHex(2)).join` * Split `aristo_transcode` => `aristo_serialise` + `aristo_blobify` why: + Different modules for different purposes + `aristo_serialise`: RLP encoding/decoding + `aristo_blobify`: Aristo database encoding/decoding * Compacted representation of small nodes' links instead of Keccak hashes why: Ethereum MPTs use Keccak hashes as node links if the size of an RLP encoded node is at least 32 bytes. Otherwise, the RLP encoded node value is used as a pseudo node link (rather than a hash.) Such a node is nor stored on key-value database. Rather the RLP encoded node value is stored instead of a lode link in a parent node instead. Only for the root hash, the top level node is always referred to by the hash. This feature needed an abstraction of the `HashKey` object which is now either a hash or a blob of length at most 31 bytes. This leaves two ways of representing an empty/void `HashKey` type, either as an empty blob of zero length, or the hash of an empty blob. * Update `CoreDb` interface (mainly reducing logger noise) * Fix copyright years (to make `Lint` happy)

Core db update providing additional results code interface (#1776) * Split `core_db/base.nim` into several sources * Rename `core_db/legacy.nim` => `core_db/legacy_db.nim` * Update `CoreDb` API, dual methods returning `Result[]` or plain value detail: Plain value methods implemet the legacy API, they defect on error results * Redesign `CoreDB` direct backend access why: Made the `backend` directive integral part of the API * Discontinue providing unused or otherwise available functions details: + setTransactionID() removed, not used and not easily replicable in Aristo + maybeGet() removed, available via direct backend access + newPhk() removed, never used & was experimental anyway * Update/reorg backend API why: + Added error print function `$$()` + General descriptor completion (and optional validation) via `bless()` * Update `Aristo`/`Kvt` exception handling why: Avoid `CatchableError` exceptions, rather pass them as error code where appropriate. * More `CoreDB` compliant `Aristo` and `Kvt` methods details: + Providing functions like `contains()`, `getVtxRc()` (returns `Result[]`). + Additional error code: `NotImplemented` * Rewrite/reorg of Aristo DB constructor why: Previously used global object `DefaultQidLayoutRef` as default initialiser.

Core db and aristo updates for destructor and tx logic (#1894) * Disable `TransactionID` related functions from `state_db.nim` why: Functions `getCommittedStorage()` and `updateOriginalRoot()` from the `state_db` module are nowhere used. The emulation of a legacy `TransactionID` type functionality is administratively expensive to provide by `Aristo` (the legacy DB version is only partially implemented, anyway). As there is no other place where `TransactionID`s are used, they will not be provided by the `Aristo` variant of the `CoreDb`. For the legacy DB API, nothing will change. * Fix copyright headers in source code * Get rid of compiler warning * Update Aristo code, remove unused `merge()` variant, export `hashify()` why: Adapt to upcoming `CoreDb` wrapper * Remove synced tx feature from `Aristo` why: + This feature allowed to synchronise transaction methods like begin, commit, and rollback for a group of descriptors. + The feature is over engineered and not needed for `CoreDb`, neither is it complete (some convergence features missing.) * Add debugging helpers to `Kvt` also: Update database iterator, add count variable yield argument similar to `Aristo`. * Provide optional destructors for `CoreDb` API why; For the upcoming Aristo wrapper, this allows to control when certain smart destruction and update can take place. The auto destructor works fine in general when the storage/cache strategy is known and acceptable when creating descriptors. * Add update option for `CoreDb` API function `hash()` why; The hash function is typically used to get the state root of the MPT. Due to lazy hashing, this might be not available on the `Aristo` DB. So the `update` function asks for re-hashing the gurrent state changes if needed. * Update API tracking log mode: `info` => `debug * Use shared `Kvt` descriptor in new Ledger API why: No need to create a new descriptor all the time

Aristo db allow shorter than 64 nibbles path keys (#1864) * Aristo: Single `FetchPathNotFound` error in `fetchXxx()` and `hasPath()` why: Missing path hike returns too many detailed reasons why it failed which becomes cumbersome to handle. also: Renamed `contains()` => `hasPath()` which disables the `in` operator on non-boolean `contains()` functions * Kvt: Renamed `contains()` => `hasKey()` why: which disables the `in` operator on non-boolean `contains()` functions * Aristo: Generalising `HashID` by variable length `PathID` why: There are cases when the `Aristo` database is to be used with shorter than 64 nibbles keys when handling transactions indexes with sequence IDs. caveat: This patch only works reliable for full length `PathID` values. Tests for shorter `PathID` values are currently missing.

Aristo db implement filter storage scheduler (#1713) * Rename FilterID => QueueID why: The current usage does not identify a particular filter but uses it as storage tag to manage it on the database (to be organised in a set of FIFOs or queues.) * Split `aristo_filter` source into sub-files why: Make space for filter management API * Store filter queue IDs in pairs on the backend why: Any pair will will describe a FIFO accessed by bottom/top IDs * Reorg some source file names why: The "aristo_" prefix for make local/private files is tedious to use, so removed. * Implement filter slot scheduler details: Filters will be stored on the database on cascaded FIFOs. When a FIFO queue is full, some filter items are bundled together and stored on the next FIFO.

This will eventually be an access layer for emulating a backend with multiple/historic state roots. * Re-factor `persistent()` with filter between backend/tx-cache => `stow()` why: The filter provides an abstraction from the physically stored data on disk. So, there can be several MPT instances using the same disk data with different state roots. Of course, all the MPT instances should not differ too much for practical reasons :).
