* Nimbus folder environment update details: * Integrated `CoreDbRef` for the sources in the `nimbus` sub-folder. * The `nimbus` program does not compile yet as it needs the updates in the parallel `stateless` sub-folder. * Stateless environment update details: * Integrated `CoreDbRef` for the sources in the `stateless` sub-folder. * The `nimbus` program compiles now. * Premix environment update details: * Integrated `CoreDbRef` for the sources in the `premix` sub-folder. * Fluffy environment update details: * Integrated `CoreDbRef` for the sources in the `fluffy` sub-folder. * Tools environment update details: * Integrated `CoreDbRef` for the sources in the `tools` sub-folder. * Nodocker environment update details: * Integrated `CoreDbRef` for the sources in the `hive_integration/nodocker` sub-folder. * Tests environment update details: * Integrated `CoreDbRef` for the sources in the `tests` sub-folder. * The unit tests compile and run cleanly now. * Generalise `CoreDbRef` to any `select_backend` supported database why: Generalisation was just missed due to overcoming some compiler oddity which was tied to rocksdb for testing. * Suppress compiler warning for `newChainDB()` why: Warning was added to this function which must be wrapped so that any `CatchableError` is re-raised as `Defect`. * Split off persistent `CoreDbRef` constructor into separate file why: This allows to compile a memory only database version without linking the backend library. * Use memory `CoreDbRef` database by default detail: Persistent DB constructor needs to import `db/core_db/persistent why: Most tests use memory DB anyway. This avoids linking `-lrocksdb` or any other backend by default. * fix `toLegacyBackend()` availability check why: got garbled after memory/persistent split. * Clarify raw access to MPT for snap sync handler why: Logically, `kvt` is not the raw access for the hexary trie (although this holds for the legacy database)
