This PR makes it easy to generate and execute testcases for VM arithmetic operations. By enabling and running the testcase TestWriteExpectedValues, a set of json files are created which contain input and output for each arith operation.
The test TestJsonTestcases executes all of those tests.

While meaningless as is, this PR makes it less risky to make changes (optimizations) to the vm operations, since there will be a larger body of testcases.

* all: simplify timestamps to uint64

* tests: update definitions

* clef, faucet, mobile: leftover uint64 fixups

* ethash: fix tests

* graphql: update schema for timestamp

* ethash: remove unused variable

core: prefetch next block state concurrently

console: handle eth.coinbase throws

light, params: update CHTs, integrate CHT for Goerli too

Corrected error for ExitWhenSyncedFlag, clarifying that the program exits after syncing completes.

swarm/network:   hive bug: needed shallow peers are not sent to nodes beyond connection's proximity order (#19326)

* swarm/network: fix hive bug not sending shallow peers

-  hive bug: needed shallow peers were not sent to nodes beyond connection's proximity order
- add extensive protocol exchange tests for initial subPeersMsg-peersMsg exchange
- modify bzzProtocolTester to allow pregenerated overlay addresses

* swarm/network: attempt to fix hive persistance test

* swarm/network: fix TestHiveStatePersistance (#1320)

* swarm/network: remove trace lines from the hive persistance test

* address PR review comments

* swarm/network: address PR comments on TestInitialPeersMsg

 * eliminate *testing.T argument from bzz/hive protocoltesters

 * add random (0 to MaxPeersPerPO) peers for each po
 * add extra peers closer to pivot than control

core/vm: Correct the Memory Gas Overflow condition

Add methods that allow for the unpacking of event logs into maps (allows for agnostic unpacking of logs)

core: cache tx signature before obtaining lock

previous overflow condition is too big to use.
0x7FFFFFFFF squre operation is overflowed uint64.

0x7FFFFFFFF^2 = 0x3F FFFF FFF0 0000 0001

* contracts/ens: revert bmt to keccak256

* contracts/ens: fix keccak256 hash code comment

Solves #15210 without changing consensus, in a backwards compatible way,
by adding tx inclusion information to the Receipt struct.

core: 3rd try on splitting the trie metrics correctly

eth: remove redundant chain config fields

Fixes #19337

This PR is a more advanced form of the dirty-to-clean cacher (#18995),
where we reuse previous database write batches as datasets to uncache,
saving a dirty-trie-iteration and a dirty-trie-rlp-reencoding per block.

This PR fixes two issues in the PoW calculation of a Whisper envelope,
compared to the spec (see PoW Requirements):

- The pow is supposed to take the leading number of zeroes (i.e. most
  significant zeroes) and what it did was to take the number of trailing
  zeroes (i.e. least significant zeroes). It has been fixed to match what
  the spec and Parity does.
- The spec expects to use the size of the RLP encoded envelope, and it took
  something else, as described in #18070.
