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

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.

Refactor interpreter dispatch (#65)
* move forks constants, rename errors

* Move vm/utils to vm/interpreter/utils

* initial opcodes refactoring

* Add refactored Comparison & Bitwise Logic Operations

* Add sha3 and address, simplify macro, support pop 0

* balance, origin, caller, callValue

* fix gas copy opcodes gas costs, add callDataLoad/Size/Copy, CodeSize/Copy and gas price opcode

* Update with 30s, 40s, 50s opcodes + impl of balance + stack improvement

* add push, dup, swap, log, create and call operations

* finish opcode implementation

* Add the new dispatching logic

* Pass the opcode test

* Make test_vm_json compile

* halt execution without exceptions for Return, Revert, selfdestruct (fix #62)

* Properly catch and recover from EVM exceptions (stack underflow ...)

* Fix byte op

* Fix jump regressions

* Update for latest devel, don't import old dispatch code as quasiBoolean macro is broken by latest devel

* Fix sha3 regression on empty memory slice and until end of range slice

* Fix padding / range error on expXY_success (gas computation left)

* update logging procs

* Add tracing - expXY_success is not a regression, sload stub was accidentally passing the test

* Reuse the same stub as OO implementation

* Delete previous opcode implementation

* Delete object oriented fork code

* Delete exceptions that were used as control flows

* delete base.nim 🔥, yet another OO remnants

* Delete opcode table

* Enable omputed gotos and compile-time gas fees

* Revert const gasCosts -> generates SIGSEGV

* inline push, swap and dup opcodes

* loggers are now template again, why does this pass new tests?

* Trigger CI rebuild after rocksdb fix https://github.com/status-im/nim-rocksdb/pull/5

* Address review comment on "push" + VMTests in debug mode (not release)

* Address review comment: don't tag fork by default, make opcode impl grepable

* Static compilation fixes after rebasing

* fix the initialization of the VM database

* add a missing import

* Deactivate balance and sload test following #59

* Reactivate stack check (deactivated in #59, necessary to pass tests)

* Merge remaining opcodes implementation from #59

* Merge callDataLoad and codeCopy fixes, todo simplify see #67

zah 18b7bbb3b0 Implemented most of the stubbed-out state handling instructions (#59)
Merge note: currently cannot compile due to `quasiBoolean` (#63). This will be solved by https://github.com/status-im/nimbus/pull/65
----

* Implemented most of the stubbed out state handling instructions

The code compiles, but still fails at the moment due to incorrect

initialization of the VM. Don't merge yet. More commits will be
pushed in the coming days.

* Fixed crash

* trie put and del are void now

* getBlockTransactionData and getReceipts

* Working code for extcodesize0.json

* fix origin.json

* fix calldatasize1

* fix calldataloadSizeTooHighPartial

* fix calldataloadSizeTooHigh

* more efficient PushX implementation

* fix and, or, xor

* memory: use a template again and avoid (?) a cstring-> string conversion

* Fix stack test regression

* Fix recursive dependency on logging_ops, test_vm_json compiles but regression :/

* Fix signextend regression

* Fix 3 signed test and sha3 test
