move db init to init (#2552)
When using the common interface, the database always (potentially) needs
init - take the opportunity to log some basic database info on startup.

Use `Hash256` directly for account path (#2439)
Account paths are always a hash - passing it around as such helps avoid
confusion as to how long it is

Only use pre hashed addresses as account keys (#2424)
* Normalised storage tree addressing in function prototypes

detail:
  Argument list is always `<db> <account-path> <slot-path> ..` with
  both path arguments as `openArray[]`

* Remove cruft

* CoreDb internally Use full account paths rather than addresses

* Update API logging

* Use hashed account address only in prototypes

why:
  This avoids unnecessary repeated hashing of the same account address.
  The burden of doing that is upon the application. In the case here,
  the ledger caches all kinds of stuff anyway so it is common sense to
  exploit that for account address hashes.

caveat:
  Using `openArray[byte]` argument types for hashed accounts is inherently
  fragile. In non-release mode, a length verification `doAssert` is
  enabled by default.

* No accPath in data record (use `AristoAccount` as `CoreDbAccount`)

* Remove now unused `eAddr` field from ledger `AccountRef` type

why:
  Is duplicate of lookup key

* Avoid merging the account record/statement in the ledger twice.

Update storage tree admin (#2419)
* Tighten `CoreDb` API for accounts

why:
  Apart from cruft, the way to fetch the accounts state root via a
  `CoreDbColRef` record was unnecessarily complicated.

* Extend `CoreDb` API for accounts to cover storage tries

why:
  In future, this will make the notion of column objects obsolete. Storage
  trees will then be indexed by the account address rather than the vertex
  ID equivalent like a `CoreDbColRef`.

* Apply new/extended accounts API to ledger and tests

details:
  This makes the `distinct_ledger` module obsolete

* Remove column object constructors

why:
  They were needed as an abstraction of MPT sub-trees including storage
  trees. Now, storage trees are handled by the account (e.g. via address)
  they belong to and all other trees can be identified by a constant well
  known vertex ID. So there is no need for column objects anymore.

  Still there are some left-over column object methods wnich will be
  removed next.

* Remove `serialise()` and `PayloadRef` from default Aristo API

why:
  Not needed. `PayloadRef` was used for unstructured/unknown payload
  formats (account or blob) and `serialise()` was used for decodng
  `PayloadRef`. Now it is known in advance what the payload looks
  like.

* Added query function `hasStorageData()` whether a storage area exists

why:
  Useful for supporting `slotStateEmpty()` of the `CoreDb` API

* In the `Ledger` replace `storage.stateEmpty()` by 	`slotStateEmpty()`

* On Aristo, hide the storage root/vertex ID in the `PayloadRef`

why:
  The storage vertex ID is fully controlled by Aristo while the
  `AristoAccount` object is controlled by the application. With the
  storage root part of the `AristoAccount` object, there was a useless
  administrative burden to keep that storage root field up to date.

* Remove cruft, update comments etc.

* Update changed MPT access paradigms

why:
  Fixes verified proxy tests

* Fluffy cosmetics

* CoreDb: Provide default db backend symbols

why:
  Handy for running `Aristo` against standard tests

note:
  These defaults are currently set to legacy DB types. The must be
  enabled manually in `db/core_db.nim`.

* Provide `Aristo` for macro assembler related tests

caveat:
  Some tests use `initStorageTrie()` which lets `Aristo` bail out. The
  test need to run on `distinct_ledgers` (or something like) rather than
  `distinct_tries`.

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)

* Nimbus folder environment update

details:

* The `nimbus` program does not compile yet as it needs the updates
  in the parallel `stateless` sub-folder.

* The `nimbus` program compiles now.

  `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)

Added basic async capabilities for vm2. (#1260)
* Added basic async capabilities for vm2.

This is a whole new Git branch, not the same one as last time
(https://github.com/status-im/nimbus-eth1/pull/1250) - there wasn't
much worth salvaging. Main differences:

I didn't do the "each opcode has to specify an async handler" junk
that I put in last time. Instead, in oph_memory.nim you can see
sloadOp calling asyncChainTo and passing in an async operation.
That async operation is then run by the execCallOrCreate (or
asyncExecCallOrCreate) code in interpreter_dispatch.nim.

In the test code, the (previously existing) macro called "assembler"
now allows you to add a section called "initialStorage", specifying
fake data to be used by the EVM computation run by that test. (In
the long run we'll obviously want to write tests that for-real use
the JSON-RPC API to asynchronously fetch data; for now, this was
just an expedient way to write a basic unit test that exercises the
async-EVM code pathway.)

There's also a new macro called "concurrentAssemblers" that allows
you to write a test that runs multiple assemblers concurrently (and
then waits for them all to finish). There's one example test using
this, in test_op_memory_lazy.nim, though you can't actually see it
doing so unless you uncomment some echo statements in
async_operations.nim (in which case you can see the two concurrently
running EVM computations each printing out what they're doing, and
you'll see that they interleave).

A question: is it possible to make EVMC work asynchronously? (For
now, this code compiles and "make test" passes even if ENABLE_EVMC
is turned on, but it doesn't actually work asynchronously, it just
falls back on doing the usual synchronous EVMC thing. See
FIXME-asyncAndEvmc.)

* Moved the AsyncOperationFactory to the BaseVMState object.

* Made the AsyncOperationFactory into a table of fn pointers.

Also ditched the plain-data Vm2AsyncOperation type; it wasn't
really serving much purpose. Instead, the pendingAsyncOperation
field directly contains the Future.

* Removed the hasStorage idea.

It's not the right solution to the "how do we know whether we
still need to fetch the storage value or not?" problem. I
haven't implemented the right solution yet, but at least
we're better off not putting in a wrong one.

* Added/modified/removed some comments.

(Based on feedback on the PR.)

* Removed the waitFor from execCallOrCreate.

There was some back-and-forth in the PR regarding whether nested
waitFor calls are acceptable:

https://github.com/status-im/nimbus-eth1/pull/1260#discussion_r998587449

The eventual decision was to just change the waitFor to a doAssert
(since we probably won't want this extra functionality when running
synchronously anyway) to make sure that the Future is already
finished.

Redesign of BaseVMState descriptor (#923)
* Redesign of BaseVMState descriptor

why:
  BaseVMState provides an environment for executing transactions. The
  current descriptor also provides data that cannot generally be known
  within the execution environment, e.g. the total gasUsed which is
  available not before after all transactions have finished.

  Also, the BaseVMState constructor has been replaced by a constructor
  that does not need pre-initialised input of the account database.

also:
  Previous constructor and some fields are provided with a deprecated
  annotation (producing a lot of noise.)

* Replace legacy directives in production sources

* Replace legacy directives in unit test sources

* fix CI (missing premix update)

* Remove legacy directives

* chase CI problem

* rebased

* Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation

why:
  Constructing a new 'AccountsCache' descriptor can be avoided sometimes
  when the current state root is properly positioned already. Such a
  feature existed already as the update function 'initStateDB()' for the
  'BaseChanDB' where the accounts cache was linked into this desctiptor.

  The function 'initStateDB()' was removed and re-implemented into the
  'BaseVmState' constructor without optimisation. The old version was of
  restricted use as a wrong accounts cache state would unconditionally
  throw an exception rather than conceptually ask for a remedy.

  The optimised 'BaseVmState' re-initialisation has been implemented for
  the 'persistBlocks()' function.

also:
  moved some test helpers to 'test/replay' folder

* Remove unused & undocumented fields from Chain descriptor

why:
  Reduces attack surface in general & improves reading the code.

move stateDB from VMState to chainDB
previously, every time the VMState was created, it will also create
new stateDB, and this action will nullify the advantages of cached accounts.

the new changes will conserve the accounts cache if the executed blocks
are contiguous. if not the stateDB need to be reinited.

this changes also allow rpcCallEvm and rpcEstimateGas executed properly
using current stateDB instead of creating new one each time they are called.

Assembler: First asmSetupComputation to support asmCallEvm
In the `macro_assembler` test code, `initComputation` is another variant of
`rpcSetupComputation` and `txSetupComputation` with slightly different
paremeters.  The similarity is obvious.

It is a special setup for testing, though, as it requires a contract-creation
transaction for parameters, but sets up a `CALL` execution not `CREATE`.

Gather this into `call_evm`: `initComputation` -> `asmSetupComputation`.
