Simple stupid key-value table companion for Aristo DB (#1746) why: Additional tables needed for the `CoreDB` object with separate key-value table and MPT. details: + Stripped down copy of Aristo DB to have a similar look'n feel. Otherwise it is just a posh way for accessing `Table` objects or `RocksDB` data. + No unit tests yet, will be tested on the go.

Triggered write event for kvt (#2351) * bump rockdb * Rename `KVT` objects related to filters according to `Aristo` naming details: filter* => delta* roFilter => balancer * Compulsory error handling if `persistent()` fails * Add return code to `reCentre()` why: Might eventually fail if re-centring is blocked. Some logic will be added in subsequent patch sets. * Add column families from earlier session to rocksdb in opening procedure why: All previously used CFs must be declared when re-opening an existing database. * Update `init()` and add rocksdb `reinit()` methods for changing parameters why: Opening a set column families (with different open options) must span at least the ones that are already on disk. * Provide write-trigger-event interface into `Aristo` backend why: This allows to save data from a guest application (think `KVT`) to get synced with the write cycle so the guest and `Aristo` save all atomically. * Use `KVT` with new column family interface from `Aristo` * Remove obsolete guest interface * Implement `KVT` piggyback on `Aristo` backend * CoreDb: Add separate `KVT`/`Aristo` backend mode for debugging * Remove `rocks_db` import from `persist()` function why: Some systems (i.p `fluffy` and friends) use the `Aristo` memory backend emulation and do not link against rocksdb when building the application. So this should fix that problem.

Kvt remodel tx and forked descriptors (#2168) * Aristo: Generalise alien/guest interface for piggiback on database * Aristo: Code cosmetics * CoreDb+Kvt: Update transaction API why: Use single addressable function `forkTx(backLevel: int)` as used in `Aristo`. So `Kvt` can be synced simultaneously to `Aristo`. also: Refactored `kvt_tx.nim` in a similar fashion to `Aristo`. * Kvt: Replace `LayerDelta` object by reference why: Will be needed when introducing filters * Kvt: Remodel backend filter facility similar to `Aristo` why: This allows to operate on several KVT instances simultaneously. * CoreDb+Kvt: Fix on-disk storage why: Overlooked name change: `stow()` => `persist()` for permanent storage * Fix copyright headers

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`)

Core db simplify new api storage modes (#2075) * Aristo+Kvt: Fix backend `dup()` function in api setup why: Backend object is subject to an inheritance cascade which was not taken care of, before. Only the base object was duplicated. * Kvt: Simplify DB clone/peers management * Aristo: Simplify DB clone/peers management * Aristo: Adjust unit test for working with memory DB only why: This currently causes some memory corruption persumably in the `libc` background layer. * CoredDb+Kvt: Simplify API for KVT why: Simplified storage models (was over engineered) for better performance and code maintenance. * CoredDb+Aristo: Simplify API for `Aristo` why: Only single database state needed here. Accessing a similar state will be implemented from outside this module using a context layer. This gives better performance and improves code maintenance. * Fix Copyright headers * CoreDb: Turn off API tracking why: CI would ot go through. Was accidentally turned on.
