Simplify aristo tree deletion functionality (#2563)
* Cleaning up, removing cruft and debugging statements

* Make `aristo_delta` fluffy compatible

why:
  A sub-module that uses `chronicles` must import all possible
  modules used by a parent module that imports the sub-module.

* update TODO

Aristo lazily delete larger subtrees (#2560)
* Extract sub-tree deletion functions into separate sub-modules

* Move/rename `aristo_desc.accLruSize` => `aristo_constants.ACC_LRU_SIZE`

* Lazily delete sub-trees

why:
  This gives some control of the memory used to keep the deleted vertices
  in the cached layers. For larger sub-trees, keys and vertices might be
  on the persistent backend to a large extend. This would pull an amount
  of extra information from the backend into the cached layer.

  For lazy deleting it is enough to remember sub-trees by a small set of
  (at most 16) sub-roots to be processed when storing persistent data.
  Marking the tree root deleted immediately allows to let most of the code
  base work as before.

* Comments and cosmetics

* No need to import all for `Aristo` here

* Kludge to make `chronicle` usage in sub-modules work with `fluffy`

why:
  That `fluffy` would not run with any logging in `core_deb` is a problem
  I have known for a while. Up to now, logging was only used for debugging.

  With the current `Aristo` PR, there are cases where logging might be
  wanted but this works only if `chronicles` runs without the
  `json[dynamic]` sinks.

  So this should be re-visited.

* More of a kludge

Cache a storage root ID forever in the leaf payload of an account (#2551)
details:
  Stale root IDs are marked disabled while the ID is kept in the leaf
  payload.

why:
  This might lead to further caching advantages.

Provide portal proof functionality with coredb (#2550)
* Provide portal proof functions in `aristo_api`

why:
  So it can be fully supported by `CoreDb`

* Fix prototype in `kvt_api`

* Fix node constructor for account leafs with storage trees

* Provide simple path check based on portal proof functionality

* Provide portal proof functionality in `CoreDb`

* Update TODO list

Revive json tracer unit tests (#2538)
* Some `Aristo` clean-ups/updates

* Re-implemented core-db tracer functionality

* Rename nimbus tracer `no-tracer.nim` => `tracer.nim`

why:
  Restore original name for easy diff tracking with upcoming update

* Update nimbus tracer using new core-db tracer functionality

* Updating json tracer unit tests

* Enable json tracer unit tests

Provide partial tree support for preloading tests (#2536)
* Implement partial trees

why:
  This is currently needed for unit tests to pre-load the database
  with test data similar to `proof` node pre-load.

  The basic features for `snap-sync` boundary proofs are available
  as well for future use. What is missing is the final proof verification
  and a complete storage data load/merge function (stub is available.)

* Cosmetics, clean up

Hash keys and hash256 revisited (#2497)
* Remove cruft left-over from PR #2494

* TODO

* Update comments on `HashKey` type values

* Remove obsolete hash key conversion flag `forceRoot`

why:
  Is treated implicitly by having vertex keys as `HashKey` type and
  root vertex states converted to `Hash256`

Core db remove legacy phrases (#2468)
* Rename `newKvt()` -> `ctx.getKvt()`

why:
  Clean up legacy shortcut. Also, the `KVT` returned is not instantiated
  but refers to the shared `KVT` that resides in a context which is a
  generalisation of an in-memory database fork. The function `ctx`
  retrieves the default context.

* Rename `newTransaction()` -> `ctx.newTransaction()`

why:
  Clean up legacy shortcut. The transaction is applied to a context as a
  generalisation of an in-memory database fork. The function `ctx`
  retrieves the default context.

* Rename `getColumn(CtGeneric)` -> `getGeneric()`

why:
  No more a list of well known sub-tries needed, a single one is enough.
  In fact, `getColumn()` did only support a single sub-tree by now.

* Reduce TODO list

Aristo code cosmetics and tests update (#2434)
* Update some docu

* Resolve obsolete compile time option

why:
  Not optional anymore

* Update checks

why:
  The notion of what constitutes a valid `Aristo` db has changed due to
  (even more) lazy calculating Merkle hash keys.

* Disable redundant unit test for production

Coredb fix storage tree issues (#2317)
* Code cosmetics

* Re-org `aristo_merge`, internally split into sub-modules

why:
  Became a burden for maintenance because it hosts two different
  functionalities under the same merge paradigm: account/data merge
  and snap proof merge where the latter produces a partial trie.

* Fix CoreDb tracer

* Ledger: fix potential account vs. storage tree sync problems

* Remove bound on the size of removable whole storage trees

* Activate `test_tracer_json`

Aristo avoid storage trie update race conditions (#2251)
* Update TDD suite logger output format choices

why:
  New format is not practical for TDD as it just dumps data across a wide
  range (considerably larder than 80 columns.)

  So the new format can be turned on by function argument.

* Update unit tests samples configuration

why:
  Slightly changed the way to find the `era1` directory

* Remove compiler warnings (fix deprecated expressions and phrases)

* Update `Aristo` debugging tools

* Always update the `storageID` field of account leaf vertices

why:
  Storage tries are weekly linked to an account leaf object in that
  the `storageID` field is updated by the application.

  Previously, `Aristo` verified that leaf objects make sense when passed
  to the database. As a consequence
  * the database was inconsistent for a short while
  * the burden for correctness was all on the application which led
    to delayed error handling which is hard to debug.

  So `Aristo` will internally update the account leaf objects so that
  there are no race conditions due to the storage trie handling

* Aristo: Let `stow()`/`persist()` bail out unless there is a `VertexID(1)`

why:
  The journal and filter logic depends on the hash of the `VertexID(1)`
  which is commonly known as the state root. This implies that all
  changes to the database are somehow related to that.

* Make sure that a `Ledger` account does not overwrite the storage trie reference

why:
  Due to the abstraction of a sub-trie (now referred to as column with a
  hash describing its state) there was a weakness in the `Aristo` handler
  where an account leaf could be overwritten though changing the validity
  of the database. This has been changed and the database will now reject
  such changes.

  This patch fixes the behaviour on the application layer. In particular,
  the column handle returned by the `CoreDb` needs to be updated by
  the `Aristo` database state. This mitigates the problem that a storage
  trie might have vanished or re-apperaed with a different vertex ID.

* Fix sub-trie deletion test

why:
  Was originally hinged on `VertexID(1)` which cannot be wholesale
  deleted anymore after the last Aristo update. Also, running with
  `VertexID(2)` needs an artificial `VertexID(1)` for making `stow()`
  or `persist()` work.

* Cosmetics

* Activate `test_generalstate_json`

* Temporarily `deactivate test_tracer_json`

* Fix copyright header
