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 aristo and kvt updates preparing for integration (#1760)
* Kvt: Implemented multi-descriptor access on the same backend

why:
  This behaviour mirrors the one of Aristo and can be used for
  simultaneous transactions on Aristo + Kvt

* Kvt: Update database iterators

why:
  Forgot to run on the top layer first

* Kvt: Misc fixes

* Aristo, use `openArray[byte]` rather than `Blob` in prototype

* Aristo, by default hashify right after cloning descriptor

why:
  Typically, a completed descriptor is expected after cloning. Hashing
  can be suppressed by argument flag.

* Aristo provides `replicate()` iterator, similar to legacy `replicate()`

* Aristo API fixes and updates

* CoreDB: Rename `legacy_persistent` => `legacy_rocksdb`

why:
  More systematic, will be in line with Aristo DB which might have
  more than one persistent backends

* CoreDB: Prettify API sources

why:
  Better to read and maintain

details:
  Annotating with custom pragmas which cleans up the prototypes

* CoreDB: Update MPT/put() prototype allowing `CatchableError`

why:
  Will be needed for Aristo API (legacy is OK with `RlpError`)

Unified database frontend integration (#1670)
* Nimbus folder environment update

details:
* Integrated `CoreDbRef` for the sources in the `nimbus` sub-folder.
* The `nimbus` program does not compile yet as it needs the updates
  in the parallel `stateless` sub-folder.

* Stateless environment update

details:
* Integrated `CoreDbRef` for the sources in the `stateless` sub-folder.
* The `nimbus` program compiles now.

* Premix environment update

details:
* Integrated `CoreDbRef` for the sources in the `premix` sub-folder.

* Fluffy environment update

details:
* Integrated `CoreDbRef` for the sources in the `fluffy` sub-folder.

* Tools environment update

details:
* Integrated `CoreDbRef` for the sources in the `tools` sub-folder.

* Nodocker environment update

details:
* Integrated `CoreDbRef` for the sources in the
  `hive_integration/nodocker` sub-folder.

* Tests environment update

details:
* Integrated `CoreDbRef` for the sources in the `tests` sub-folder.
* The unit tests compile and run cleanly now.

* Generalise `CoreDbRef` to any `select_backend` supported database

why:
  Generalisation was just missed due to overcoming some compiler oddity
  which was tied to rocksdb for testing.

* Suppress compiler warning for `newChainDB()`

why:
  Warning was added to this function which must be wrapped so that
  any `CatchableError` is re-raised as `Defect`.

* Split off persistent `CoreDbRef` constructor into separate file

why:
  This allows to compile a memory only database version without linking
  the backend library.

* Use memory `CoreDbRef` database by default

detail:
 Persistent DB constructor needs to import `db/core_db/persistent

why:
 Most tests use memory DB anyway. This avoids linking `-lrocksdb` or
 any other backend by default.

* fix `toLegacyBackend()` availability check

why:
  got garbled after memory/persistent split.

* Clarify raw access to MPT for snap sync handler

why:
  Logically, `kvt` is not the raw access for the hexary trie (although
  this holds for the legacy database)

More work on withdrawals (#1482)
* Part of EIP-4895: add withdrawals processing to block processing.

* Refactoring: extracted the engine API handler bodies into procs.

Intending to implement the V2 versions next. (I need the bodies to be
in separate procs so that multiple versions can use them.)

* Working on Engine API changes for Shanghai.

* Updated nim-web3, resolved ambiguity in Hash256 type.

* Updated nim-eth3 to point to master, now that I've merged that.

* I'm confused about what's going on with engine_client.

But let's try resolving this Hash256 ambiguity.

* Still trying to fix this conflict with the Hash256 types.

* Does this work now that nimbus-eth2 has been updated?

* Corrected blockValue in getPayload responses back to UInt256.

c834f67a37

* Working on getting the withdrawals-related tests to pass.

* Fixing more of those Hash256 ambiguities.

(I'm not sure why the nim-web3 library introduced a conflicting type
named Hash256, but right now I just want to get this code to compile again.)

* Bumped a couple of libraries to fix some error messages.

* Needed to get "make fluffy-tools" to pass, too.

* Getting "make nimbus_verified_proxy" to build.
