* CoreDb: Remove crufty second/off-site KVT why: Was used to allow late `Clique` to store directly to disk * CoreDb: Remove prune flag related functionality why: Is completely legacy stuff * CoreDb: Remove dependence on legacy API (tests unsupported yet) why: Does not fully support Aristo * Re-factoring `state_db` using new API details: Only minimum changes needed to compile `nimbus` * Update tests and aux modules * Turn off legacy API and remove `distinct_tries` comment: The legacy API has now cruft status, will be removed soon * Fix copyright years * Update rpc for verified proxy --------- Co-authored-by: Jacek Sieka <jacek@status.im>
