Core db update storage root management for sub tries (#1964)
* Aristo: Re-phrase `LayerDelta` and `LayerFinal` as object references

why:
  Avoids copying in some cases

* Fix copyright header

* Aristo: Verify `leafTie.root` function argument for `merge()` proc

why:
  Zero root will lead to inconsistent DB entry

* Aristo: Update failure condition for hash labels compiler `hashify()`

why:
  Node need not be rejected as long as links are on the schedule. In
  that case, `redo[]` is to become `wff.base[]` at a later stage.

  This amends an earlier fix, part of #1952 by also testing against
  the target nodes of the `wff.base[]` sets.

* Aristo: Add storage root glue record to `hashify()` schedule

why:
  An account leaf node might refer to a non-resolvable storage root ID.
  Storage root node chains will end up at the storage root. So the link
  `storage-root->account-leaf` needs an extra item in the schedule.

* Aristo: fix error code returned by `fetchPayload()`

details:
  Final error code is implied by the error code form the `hikeUp()`
  function.

* CoreDb: Discard `createOk` argument in API `getRoot()` function

why:
  Not needed for the legacy DB. For the `Arsto` DB, a lazy approach is
  implemented where a stprage root node is created on-the-fly.

* CoreDb: Prevent `$$` logging in some cases

why:
  Logging the function `$$` is not useful when it is used for internal
  use, i.e. retrieving an an error text for logging.

* CoreDb: Add `tryHashFn()` to API for pretty printing

why:
  Pretty printing must not change the hashification status for the
  `Aristo` DB. So there is an independent API wrapper for getting the
  node hash which never updated the hashes.

* CoreDb: Discard `update` argument in API `hash()` function

why:
  When calling the API function `hash()`, the latest state is always
  wanted. For a version that uses the current state as-is without checking,
  the function `tryHash()` was added to the backend.

* CoreDb: Update opaque vertex ID objects for the `Aristo` backend

why:
  For `Aristo`, vID objects encapsulate a numeric `VertexID`
  referencing a vertex (rather than a node hash as used on the
  legacy backend.) For storage sub-tries, there might be no initial
  vertex known when the descriptor is created. So opaque vertex ID
  objects are supported without a valid `VertexID` which will be
  initalised on-the-fly when the first item is merged.

* CoreDb: Add pretty printer for opaque vertex ID objects

* Cosmetics, printing profiling data

* CoreDb: Fix segfault in `Aristo` backend when creating MPT descriptor

why:
  Missing initialisation  error

* CoreDb: Allow MPT to inherit shared context on `Aristo` backend

why:
  Creates descriptors with different storage roots for the same
  shared `Aristo` DB descriptor.

* Cosmetics, update diagnostic message items for `Aristo` backend

* Fix Copyright year

Aristo db kvt maintenance update (#1952)
* Update KVT layers abstraction

details:
  modelled after Aristo layers

* Simplified KVT database iterators (removed item counters)

why:
  Not needed for production functions

* Simplify KVT merge function `layersCc()`

* Simplified Aristo database iterators (removed item counters)

why:
  Not needed for production functions

* Update failure condition for hash labels compiler `hashify()`

why:
  Node need not be rejected as long as links are on the schedule. In
  that case, `redo[]` is to become `wff.base[]` at a later stage.

* Update merging layers and label update functions

why:
+ Merging a stack of layers with `layersCc()` could be simplified
+ Merging layers will optimise the reverse `kMap[]` table maps
  `pAmk: label->{vid, ..}` by deleting empty mappings `label->{}` where
  they are redundant.
+ Updated `layersPutLabel()` for optimising `pAmk[]` tables

Core db use differential tx layers for aristo and kvt (#1949)
* Fix kvt headers

* Provide differential layers for KVT transaction stack

why:
  Significant performance improvement

* Provide abstraction layer for database top cache layer

why:
  This will eventually implemented as a differential database layers
  or transaction layers. The latter is needed to improve performance.

behavioural changes:
  Zero vertex and keys (i.e. delete requests) are not optimised out
  until the last layer is written to the database.

* Provide differential layers for Aristo transaction stack

why:
  Significant performance improvement

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)

Core db aristo hasher profiling and timing improvement (#1938)
* Explicitly use shared `Kvt` table on `Ledger` and `Clique` lookup.

why:
  Speeds up lookup time with `Aristo` backend. For writing `Clique` data,
  the `Companion` model allows to write `Clique` data past the database
  locked by evm transactions.

* Implement `CoreDb` profiling with API tracking

why:
  Chasing time spent per APT procs ...

* Implement `Ledger` profiling with API tracking

why:
  Chasing time spent per APT procs ...

* Always hashify when commiting or storing

why:
  A dirty cache makes no sense when committing

* Make sure that a zero key is created when adding/updating vertices

why:
  This is an error fix mainly for edge cases. A typical error was
  that the root key got deleted when there were only a few vertices
  left on the DB.

* Need all created and changed vertices zero-keyed on the cache

why:
  A zero key (i.e. empty Merkle hash) indicates that a vertex key
  needs to be updated. This would not be needed immediately after
  a merge as there is an actual leaf path on the cache layer. But
  after subsequent merge and delete operations this information
  might get blurred.

* Re-org hashing algorithm

why:
  Apart from errors, the previous implementation was too slow for
  two reasons:
  + some control hashes were calculated for debugging (now all
    verification is done in `aristo_check` module)
  + the leaf paths stored on the cache are used to build the
    labelling (aka hashing) schedule; there paths were accumulated
    over successive hash sessions although it is clear that all
    keys were generated, already

Aristo db update merkle hasher (#1925)
* Register paths for added leafs because of trie re-balancing

why:
  While the payload would not change, the prefix in the leaf vertex
  would. So it needs to be flagged for hash recompilation for the
  `hashify()` module.

also:
  Make sure that `Hike` paths which might have vertex links into the
  backend filter are replaced by vertex copies before manipulating.
  Otherwise the vertices on the immutable filter might be involuntarily
  changed.

* Also check for paths where the leaf vertex is on the backend, already

why:
  A a path can have dome vertices on the top layer cache with the
  `Leaf` vertex on  the backend.

* Re-define a void `HashLabel` type.

why:
  A `HashLabel` type is a pair `(root-vertex-ID, Keccak-hash)`. Previously,
  a valid `HashLabel` consisted of a non-empty hash and a non-zero vertex
  ID. This definition leads to a non-unique representation of a void
  `HashLabel` with either root-ID or has void. This has been changed to
  the unique void `HashLabel` exactly if the hash entry is void.

* Update consistency checkers

* Re-org `hashify()` procedure

why:
  Syncing against block chain showed serious deficiencies which produced
  wrong hashes or simply bailed out with error.

  So all fringe cases (mainly due to deleted entries) could be integrated
  into the labelling schedule rather than handling separate fringe cases.

Core db update api tracking (#1907)
* Fix copyright year

* Show elapsed times with enabled `CoreDb` API tracking

* Show elapsed times with enabled `LedgerRef` API tracking

* Reorg `CoreDb` auto destructors for `Aristo` DB

why:
  While `Aristo` supports some parallelism for concurrent database access,
  this comes with a price of management overhead. With a naive approach,
  the auto-destructor will slow down execution because the ledger and
  evm treat the database in a shared mode where a DB descriptor is just
  created and thrown away shortly after.

  This is reflected in the `Coredb` abstraction layer above `Aristo`/`Kvt`
  where a few `Shared` type descriptors are cached and a shared reference
  is returned rather than a disposable new object.

* For `CoreDb` support transaction level tracking

details:
  This is mainly an extra for the legacy DB as `Aristo` and `Kvt` support
  this already.

  Also return an error on the legacy DB backend when `persistent()` is
  called while there are transactions pending (the `persistent()` call
  does nothing otherwise on the legacy backend.)

* Clear compiler warnings (remove unused variables etc.)

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

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)

Aristo db allow shorter than 64 nibbles path keys (#1864)
* Aristo: Single `FetchPathNotFound` error in `fetchXxx()` and `hasPath()`

why:
  Missing path hike returns too many detailed reasons why it failed
  which becomes cumbersome to handle.

also:
  Renamed `contains()` => `hasPath()` which disables the `in` operator on
  non-boolean 	`contains()` functions

* Kvt: Renamed `contains()` => `hasKey()`

why:
  which disables the `in` operator on non-boolean 	`contains()` functions

* Aristo: Generalising `HashID` by variable length `PathID`

why:
  There are cases when the `Aristo` database is to be used with
  shorter than 64 nibbles keys when handling transactions indexes
  with sequence IDs.

caveat:
  This patch only works reliable for full length `PathID` values. Tests
  for shorter `PathID` values are currently missing.

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.)

Fudge persistent legacy hexary db edge case (#1817)
details:

* Cosmetics: Move some unit test helpers to common sub-directory

* Extract constant from `accouns_cache.nim` => `constants.nim`

why:
  Logger dump data were wrongly dumped from the production database. This

  (instead of the memory logger.) This event in turn was enabled after
  fixing another inconsistency which just set up an empty iterator. Unit
  tests failed to detect that.

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.

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`)

Aristo db api extensions for use as core db backend (#1754)
* Update docu

* Update Aristo/Kvt constructor prototype

why:
  Previous version used an `enum` value to indicate what backend is to
  be used. This was replaced by using the backend object type.

* Rewrite `hikeUp()` return code into `Result[Hike,(Hike,AristoError)]`

why:
  Better code maintenance. Previously, the `Hike` object was returned. It
  had an internal error field so partial success was also available on
  a failure. This error field has been removed.

* Use `openArray[byte]` rather than `Blob` in functions prototypes

* Provide synchronised multi instance transactions

why:
  The `CoreDB` object was geared towards the legacy DB which used a single
  transaction for the key-value backend DB. Different state roots are
  provided by the backend database, so all instances work directly on the
  same backend.

  Aristo db instances have different in-memory mappings (aka different
  state roots) and the transactions are on top of there mappings. So each
  instance might run different transactions.

  Multi instance transactions are a compromise to converge towards the
  legacy behaviour. The synchronised transactions span over all instances
  available at the time when base transaction was opened. Instances
  created later are unaffected.

* Provide key-value pair database iterator

why:
  Needed in `CoreDB` for `replicate()` emulation

also:
  Some update of internal code

* Extend API (i.e. prototype variants)

why:
  Needed for `CoreDB` geared towards the legacy backend which has a more
  basic API than Aristo.
