* Fix vertex ID generator state handling for rocksdb backend why: * Key error in walk iterator * Needs to be loaded when opening the database * Use non-zero sub-table prefixes for rocksdb why: Handy for debugging * Fix error code for missing key on rocksdb backend why: Previously returned `VOID_HASH_KEY` rather than `GetKeyNotFound` * Explicitly copy vertex data between internal table and function/result argument why: Function argument or return reference may still refer to the same data object. * Updated error symbols why: Error symbol names for the hike module now start with the prefix `Hike`. * Write back modified branch node into local top layer cache why: With the backend available, the source of the branch node references might not be the top layer cache. So any change must be explicitely recorded.
