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 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)

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 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)
