Aristo db with storage backends (#1603) * Generalised Aristo DB constructor for any type of backend details: * Records to be deleted are represented as key-void (rather than key-value) pairs by the put-function arguments * Allow direct driver access, iterators as example implementation and for testing. * Provide backend storage interface details: Stores the top layer onto backend tables * Implemented Rocks DB backend details: Transaction based `put()` functionality Iterators (based on direct RocksDB access)

# Data record transcoders, `deblobify()` and `blobify()`
Aristo db fixes n updates needed for filter fifo (#1728) * Set scheduler state as part of the backend descriptor details: Moved type definitions `QidLayoutRef` and `QidSchedRef` to `desc_structural.nim` so that it shares the same folder as `desc_backend.nim` * Automatic filter queue table initialisation in backend details: Scheduler can be tweaked or completely disabled * Updated backend unit tests details: + some code clean up/beautification, reads better now + disabled persistent filters so that there is no automated filter management which will be implemented next * Prettify/update unit tests source code details: Mostly replacing the `check()` paradigm by `xCheck()` * Somewhat simplified backend type management why: Backend objects are labelled with a `BackendType` symbol where the `BackendVoid` label is implicitly assumed for a `nil` backend object reference. To make it easier, a `kind()` function is used now applicable to `nil` references as well. * Fix DB storage layout for filter objects why: Need to store the filter ID with the object * Implement reverse [] index on fifo why: An integer index argument on `[]` retrieves the QueueID (label) of the fifo item while a QueueID argument on `[]` retrieves the index (so it is inverse to the former variant). * Provide iterator over filters as fifo why: This iterator goes along the cascased fifo structure (i.e. in historical order)

Aristo db update delete functionality (#1621) * Fix missing branch checks in transcoder why: Symmetry problem. `Blobify()` allowed for encoding degenerate branch vertices while `Deblobify()` rejected decoding wrongly encoded data. * Update memory backend so that it rejects storing bogus vertices. why: Error behaviour made similar to the rocks DB backend. * Make sure that leaf vertex IDs are not repurposed why: This makes it easier to record leaf node changes * Update error return code for next()/right() traversal why: Returning offending vertex ID (besides error code) helps debugging * Update Merkle hasher for deleted nodes why: Not implemented, yet also: Provide cache & backend consistency check functions. This was partly re-implemented from `hashifyCheck()` * Simplify some unit tests * Fix delete function why: Was conceptually wrong

Aristo db implement filter serialisation for storage (#1695) * Remove concept of empty/blind filters why: Not needed.

For a speedy memory database, a backend-less variant should be used. * Drop the `Aristo` prefix from names `AristoLayerRef`, etc. * Suppress compiler warning why: duplicate imports * Add filter serialisation transcoder why: Will be used as storage format

Extended data Payload specs for the backend. (#1630) why: For the main tree with root vertex ID 1, the leaf nodes hold the account data. These accounts may link to sub trees the storage root node ID of which must be registered here. There is no reverse key lookup on the backend. note: These definitions are experimental. Also, there are some tests missing for validating Payload data conversions.

Aristo db update delete functionality (#1621) * Fix missing branch checks in transcoder why: Symmetry problem. `Blobify()` allowed for encoding degenerate branch vertices while `Deblobify()` rejected decoding wrongly encoded data. * Update memory backend so that it rejects storing bogus vertices. why: Error behaviour made similar to the rocks DB backend. * Make sure that leaf vertex IDs are not repurposed why: This makes it easier to record leaf node changes * Update error return code for next()/right() traversal why: Returning offending vertex ID (besides error code) helps debugging * Update Merkle hasher for deleted nodes why: Not implemented, yet also: Provide cache & backend consistency check functions. This was partly re-implemented from `hashifyCheck()` * Simplify some unit tests * Fix delete function why: Was conceptually wrong

Aristo db fixes after storage slots dump tests added (#1595) * Fix missing Merkle key removal in `merge()` * Accept optional root hash argument in `hashify()` why: For importing a full database, there will be no proof data except the root key. So this can be used to check and set the root key in the database descriptor. also: Associate vertex ID to `hashify()` error return code * Added Aristo Trie traversal function why: * step along leaf vertices in sorted order * tree/trie consistency checks when debugging * Enabled storage slots test data for Aristo DB

Aristo db use filter betw backend and tx cache (#1678) * Provide deep copy for each transaction layer why: Localising changes. Selective deep copy was just overlooked. * Generalise vertex ID generator state reorg function `vidReorg()` why: makes it somewhat easier to handle when saving layers. * Provide dummy back end descriptor `NoneBackendRef` * Optional read-only filter between backend and transaction cache why: Some staging area for accumulating changes to the backend DB. This will eventually be an access layer for emulating a backend with multiple/historic state roots. * Re-factor `persistent()` with filter between backend/tx-cache => `stow()` why: The filter provides an abstraction from the physically stored data on disk. So, there can be several MPT instances using the same disk data with different state roots. Of course, all the MPT instances should not differ too much for practical reasons :). TODO: Filter administration tools need to be provided.

To make it easier, a `kind()` function is used now applicable to `nil` references as well. * Fix DB storage layout for filter objects why: Need to store the filter ID with the object * Implement reverse [] index on fifo why: An integer index argument on `[]` retrieves the QueueID (label) of the fifo item while a QueueID argument on `[]` retrieves the index (so it is inverse to the former variant). * Provide iterator over filters as fifo why: This iterator goes along the cascased fifo structure (i.e. in historical order)

Aristo db supporting forest and layered tx architecture (#1598) * Exclude some storage tests why: These test running on external dumps slipped through. The particular dumps were reported earlier as somehow dodgy. This was changed in `#1457` but having a second look, the change on hexary_interpolate.nim(350) might be incorrect. * Redesign `Aristo DB` descriptor for transaction based layers why: Previous descriptor layout made it cumbersome to push/pop database delta layers. The new architecture keeps each layer with the full delta set relative to the database backend. * Keep root ID as part of the `Patricia Trie` leaf path why; That way, forests are supported

This avoids linking `-lrocksdb` or any other back end libraries by default. * Re-factor transaction module why: Got the paradigm wrong.
