avoid initTable (#2328)
`initTable` is obsolete since nim 0.19 and can introduce significant
memory overhead while providing no benefit (since the table will be
grown to the default initial size on first use anyway).

In particular, aristo layers will not necessarily use all tables they
initialize, for exampe when many empty accounts are being created.

Core db disable legacy api n remove distinct tries (#2299)
* CoreDb: Remove crufty second/off-site KVT

why:
  Was used to allow late `Clique` to store directly to disk

* CoreDb: Remove prune flag related functionality

why:
  Is completely legacy stuff

* CoreDb: Remove dependence on legacy API (tests unsupported yet)

why:
  Does not fully support Aristo

* Re-factoring `state_db` using new API

details:
  Only minimum changes needed to compile `nimbus`

* Update tests and aux modules

* Turn off legacy API and remove `distinct_tries`

comment:
  The legacy API has now cruft status, will be removed soon

* Fix copyright years

* Update rpc for verified proxy

Ledger activate unified accounts cache wrapper (#1939)
* Activate `LedgerRef` wrapper for `AccountsCache`

details:
  `accounts_cache.nim` methods are indirectly processed by the wrapper
  methods from `ledger.nim`.

  This works for all sources except `test_state_db.nim` where the source
  `accounts_cache.nim` is included (rather than imported) in order to
  access objects privy to the very source.

* Provide facility to switch to a preselected `LedgerRef` type

details:
  Can be set as suggestion when initialising `CommonRef`

* Update `CoreDb` test suite for better time tracking

details:
+ Allow time logging by pre-defined block intervals
+ Print `CoreDb`/`Ledger`profiling results (if enabled)

Optional accounts cache module for creating genesis (#1897)
* Split off `ReadOnlyStateDB` from `AccountStateDB` from `state_db.nim`

why:
  Apart from testing, applications use `ReadOnlyStateDB` as an easy
  way to access the accounts ledger. This is well supported by the
  `Aristo` db, but writable mode is only parially supported.

  The writable AccountStateDB` object for modifying accounts is not
  used by production code.

  So, for lecgacy and testing apps, the full support of the previous
  `AccountStateDB` is now enabled by `import db/state_db/read_write`
  and the `import db/state_db` provides read-only mode.

* Encapsulate `AccountStateDB` as `GenesisLedgerRef` or genesis creation

why:
  `AccountStateDB` has poor support for `Aristo` and is not widely used
   in favour of `AccountsLedger` (which will be abstracted as `ledger`.)

   Currently, using other than the `AccountStateDB` ledgers within the
   `GenesisLedgerRef` wrapper is experimental and test only. Eventually,
    the wrapper should disappear so that the `Ledger` object (which
    encapsulates `AccountsCache` and `AccountsLedger`) will prevail.

* For the `Ledger`, provide access to raw accounts `MPT`

why:
  This gives to the `CoreDbMptRef` descriptor from the `CoreDb` (which is
  the legacy version of 	CoreDxMptRef`.) For the new `ledger` API, the
  accounts are based on the `CoreDxMAccRef` descriptor which uses a
  particular sub-system for accounts while legacy applications use the
  `CoreDbPhkRef` equivalent of the `SecureHexaryTrie`.

  The only place where this feature will currently be used is the
 `genesis.nim` source file.

* Fix `Aristo` bugs, missing boundary checks, typos, etc.

* Verify root vertex in `MPT` and account constructors

why:
  Was missing so far, in particular the accounts constructor must
  verify `VertexID(1)

* Fix include file

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 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

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)

Some work on speculative execution (#1552)
* Recreating some of the speculative-execution code.

Not really using it yet. Also there's some new inefficiency in
memory.nim, but it's fixable - just haven't gotten around to it yet.

The big thing introduced here is the idea of "cells" for stack,
memory, and storage values. A cell is basically just a Future (though
there's also the option of making it an Identity - just a simple
distinct wrapper around a value - if you want to turn off the
asynchrony).

* Bumped nim-eth.

* Cleaned up a few comments.

* Bumped nim-secp256k1.

* Oops.

* Fixing a few compiler errors that show up with EVMC enabled.
