Experimental MP-trie (#1573) * Experimental MP-trie why: Deleting records is a infeasible with the current structure * Added vertex ID recycling management Todo: Provide some unit tests * DB layout update why: Main news is the separation of `Merkel` hashes into an extra table. details: The code fragments cover conversion between compact MPT records and Aristo DB records as well as some rudimentary cache handling for the `Merkel` hashes (i.e. the extra table entries.) todo: Add some simple unit test for the descriptor record (currently used for vertex ID management, only.) * Updated vertex ID recycling management details: added simple unit tests (mainly testing ABI) * docu update

Aristo db merkle hashify functionality added (#1593) * Keep vertex ID generator state with each db-layer why: The vertex ID generator state is part of the difference to the below layer * Move otherwise unused source to test directory * Add Merkle hash generator also: * Verification facility for debugging * Empty Merkle key hashes encoded as `EMPTY_ROOT_HASH`

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

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 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. A non-existent filter is is coded as a nil reference. * Slightly generalised backend iterators why: * VertexID as key for the ID generator state makes no sense * there will be more tables addressed by non-VertexID keys * Store serialised/blobified vertices on memory backend why: This is more in line with the RocksDB backend so more appropriate for testing when comparing behaviour. 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 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.

Aristo db implement filter serialisation for storage (#1695) * Remove concept of empty/blind filters why: Not needed. A non-existent filter is is coded as a nil reference. * Slightly generalised backend iterators why: * VertexID as key for the ID generator state makes no sense * there will be more tables addressed by non-VertexID keys * Store serialised/blobified vertices on memory backend why: This is more in line with the RocksDB backend so more appropriate for testing when comparing behaviour. 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

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

# Transaction wrappers
Aristo db refactor tx paradim (#1674) * Better error handling why: Bail out on some error as early as possible before any changes. * Implement `fetch()` as opposite of `merge()` rationale: In the `Aristo` realm, the action named `fetch()` and `merge()` indicate leaf value related actions on the MPT, while actions `get()` and `put()` handle vertex or hash key related operations that constitute the MPT. * Re-factor `merge()` prototypes why: The most used variant of `merge()` should have the simplest prototype. * Persistent DB constructor needs to import `aristo/aristo_init/persistent` why: Most applications use memory DB anyway. This avoids linking `-lrocksdb` or any other back end libraries by default. * Re-factor transaction module why: Got the paradigm wrong. The transaction descriptor did replace the database one but should be handled separately.

After defining abbreviations (and its meaning) it seems easier to use `getVtxUBE()` and `getKeyBE()`. * Integrate `hashify()` process into transaction logic why: Is now transparent unless explicitly controlled. details: Cache changes imply setting a `dirty` flag which in turn triggers `hashify()` processing in transaction and `pack()` directives. * Removed `aristo_tx.exec()` directive why: Inconsistent implementation, functionality will be provided with a different paradigm.

Aristo db traversal helpers (#1638) * Misc fixes detail: * Fix de-serialisation for account leafs * Update node recovery from unit tests * Remove `LegacyAccount` from `PayloadRef` object why: Legacy accounts use a hash key as storage root which is detrimental to the working of the Aristo database which uses a vertex ID. * Dissolve `hashify_helper` into `aristo_utils` and `aristo_transcode` why: Functions are of general interest so they should live in first level code files. * Added left/right iterators over leaf nodes * Some helper/wrapper functions that might be useful

Add items to `Aristo Trie` database (#1586) details: 1. Merging a leaf vertex merges a `Patricia Trie` path (while adding/modiying vertices) and adds a leaf node with payload 2. Merging a Merkel node merges a single vertex to the `Patricia Trie` and registers merkel hashes 3. Action 2 can be used before action 1 in order to construct a Merkel proof as required for handling `snap/1` data. 4. Unit tests show that action 3 is benign for now :)
