…nSync (erigontech#6222) Change from: ``` begin(TxNoSync) exec new block, index nee data do limited pruning commit() send notifications about new data arrival to other apps, they may start reading new data at this time (by new read transactions) ``` Change to: ``` begin(TxNoSync) exec new block, index nee data commit() // no fsync here send notifications about new data arrival to other apps, they may start reading new data at this time (by new read transactions) begin() do pruning commit() // fsync here ``` it allows notify earlier. Fsync (of all changes) on modern drives is fast, but on cloud-drives it’s about 1sec in worst cases.
This ensures that the filter bad transactions can use the same context each time, so increases an account nonce in the first batch of transactions is committed to the simulation just in case the same account appears in the next batch of transactions. Also makes use of the new txpool candidate functionality to ensure we're getting fresh transactions each time.

This is described in: https://github.com/ethereum/consensus-specs/blob/dev/specs/phase0/beacon-chain.md#compute_shuffled_index.

) Works around a flaw in the upgrade logic of the system contracts. Since they are updated directly, without first being self-destructed and then re-created, the usual incarnation logic does not get activated, and all historical records of the code of these contracts are retrieved as the most recent version. This problem will not exist in erigon3, but until then, a workaround will be used to access code of such contracts through a special structure, `SystemContractCodeLookup` Fixes erigontech#5865 Co-authored-by: Alexey Sharp <alexeysharp@Alexeys-iMac.local>

Prior to withdrawals, it was extremely unlikely to have short (RLP < 32) top trie nodes outside test scenarios.
Postfix after PR erigontech#6440
Run tests from a new repo https://github.com/ethereum/execution-spec-tests. Also introduce `HashCheck()` function that checks correctness of block's uncle, transaction, and withdrawals hashes.
