Implementation of Nimbus eth_getProof RPC Endpoint. (#1960)
* Initial implementation of eth_getProof endpoint.

* Implemented generation of account and storage proofs.

* Minor fixes and additional tests.

* Refactor getBranch code into a separate file.

* Improve usage of test data.

* Fix copyright year.

* Return zero hash for codeHash and storageHash if account doesn't exist.

* Update copyright notice and moved trie key hashing to inside getBranch proc.

Fix default pruning for ledger and update core db and ledger logging (#1861)
* Make sure that storage tries are not pruned (by default) on the new Ledger API

why:
  Pruning might kill some unwanted entries from storage tries ending up with an unstable database
  leading to crashes.

* Implement `CoreDb` and `LedgerRef` API tracing

details:
+ Locally enabled at compile time via constants `ProvideCoreDbLegacyAPI`
  and `EnableApiTracking` in either `base.nim` source
+ If enabled it can be selectively turned on/off via public switches in
  the `CoreDb` descriptor.

* Allow suppressing opportunistic `ifNecessaryGetXxx()` functions

why:
  Better troubleshooting when the system crashes (assertions will then
  most probably happen outside an `async` function.)

Ledger abstraction for accounts cache (#1824)
* Provide TDD/debug facility for inspecting `persistBlocks()` working

detail:
+ Make sure that the last block of a test sample is the first batch
  item in `persistBlocks()`.
+ Additionally, allow `AccountsCache` API tracing by setting the flag
  `extraTraceMessages = true` in the file `accounts_cache.nim`

* Overload AccountsCache by abstraction wrapper

details:
  Can facilitate CoreDb API switch, details in `ledger/README.md`.

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. This object was created at compile time which lead to
  non-gc safe functions.

* Update nimbus/db/core_db/legacy_db.nim

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)

Refactored to introduce distinct types AccountsTrie and StorageTrie. (#1490)
This is in preparation for working on stateless mode; it's useful to
have a clearer and more type-safe interface for accessing accounts
versus slots.
