* 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.
