immutable validator database factoring (#2297)
* initial immutable validator database factoring * remove changes from chain_dag: this abstraction properly belongs in beacon_chain_db * add merging mutable/immutable validator portions; individually test database roundtripping of immutable validators and states-sans-immutable-validators * update test summaries * use stew/assign2 instead of Nim assignment * add reading/writing of immutable validators in chaindag * remove unused import * replace chunked k/v store of immutable validators with per-row SQL table storage * use List instead of HashList * un-stub some ncli_db code so that it uses * switch HashArray to array; move BeaconStateNoImmutableValidators from datatypes to beacon_chain_db * begin only-mutable-part state storage * uncomment some assigns * work around https://github.com/nim-lang/Nim/issues/17253 * fix most of the issues/oversights; local sim runs again * fix test suite by adding missing beaconstate field to copy function * have ncli bench also store immutable validators * extract some immutable-validator-specific code from the beacon chain db module * add more rigorous database state roundtripping, with changing validator sets * adjust ncli_db to use new schema * simplify putState/getState by moving all immutable validator accounting into beacon state DB * remove redundant test case and move code to immutable-beacon-chain module * more efficient, but still brute-force, mutable+immutable validator merging * reuse BeaconState in getState * ensure HashList/HashArray caches are cleared when reusing getState buffers; add ncli_db and a unit test to verify this * HashList.clear() -> HashList.clearCache() * only copy incrementally necessary immutable validators * increase strictness of test cases and fix/work around resulting HashList cache invalidation issues * remove explanatory scaffolding * allow for storage of full (with all validators) states for backwards/forwards-compatibility * adjust DbSeq type usage * store full, with-validators, state every 64 epochs to enable reverting versions * reduce memory allocation and intermediate objects in state storage codepath * eliminate allocation/copying through intermediate BeaconStateNoImmutableValidators objects * skip benchmarking initial genesis-validator-heavy state store * always store new-style state and sometimes old-style state * document intent behind BeaconState/Validator type-punnery * more accurate failure message on SQLite in-memory database initialization failure
