Includes a simple test harness for the merge interop M1 milestone
This aims to enable connecting nimbus-eth2 to nimbus-eth1 within
the testing protocol described here:
https://github.com/status-im/nimbus-eth2/blob/amphora-merge-interop/docs/interop_merge.md
To execute the work-in-progress test, please run:
In terminal 1:
tests/amphora/launch-nimbus.sh
In terminal 2:
tests/amphora/check-merge-test-vectors.sh
previously, every time the VMState was created, it will also create
new stateDB, and this action will nullify the advantages of cached accounts.
the new changes will conserve the accounts cache if the executed blocks
are contiguous. if not the stateDB need to be reinited.
this changes also allow rpcCallEvm and rpcEstimateGas executed properly
using current stateDB instead of creating new one each time they are called.
In RPC `eth_protocolVersion`, look at the live `EthereumNode` to find which
version of `eth/NN` protocol is active, instead of trusting a compile-time
constant. It's better to check dynamically. GraphQL already does this.
As a result, the RPC code doesn't depend on `eth_protocol` any more.
To make sure there are no more accidental users of the old constant,
`protocolVersion` is no longer exported from `protocol_eth65`.
(The simplest way to support `eth/65` was to make `eth_protocolVersion` use
`protocol_eth65.protocolVersion`, to get 65. But that's silly. More
seriously, when we add another version (`eth/66`) running alongside `eth/65`,
that expression would still compile ok yet return the wrong value, while still
passing the RPC test suite.)

This is the main patch which removes Whisper code from `nimbus-eth1` code.
It removes all configuration, help, startup, JSON-RPC calls and most types.
Note, there is still Whisper functionality in `nim-eth`. Also, the "wrapper"
under `wrappers/` isn't dealt with by this change, but it's not built by
default (and might not currently work).

instead of using stdlib/json, now we switch to json_serialization
the result is much tidier code and more robust when parsing
optional fields.
fixes#635
`estimateGas` used by JSON-RPC is another way to setup and call the EVM,
also used by GraphQL. Move it to `transaction/call_evm`.
This function has too much direct knowledge of details that shouldn't be used
outside transaction handling code, details we need to change when changing the
db and transaction memory layer.
Moving this one exposed quite a bit of abstraction leakage, as it calls
directly to the hexary trie db around `processTransaction`.
It looks like the _intended_ functionality of `estimateGas` is similar to
`rpcDoCall` with the only real difference being to not store the final state.
It looks like the extra stuff in `estimateGas` compared with `doCall` is a
messy workaround for computation not exposing the right API ("don't save final
state") for RPC to use.

Start gathering the functions that call the EVM into one place,
`transaction/call_evm.nim`.
This is first of a series of changes to gather all ways the EVM is called to
one place. Duplicate, slightly different setup functions have accumulated over
time, each with some knowledge of EVM internals. When they are brought
together, these methods will be changed to use a single entry point to the EVM,
allowing the entry point to be refactored, EVMC to be completed, and async
concurrency to be implemented on top. This also simplifies the callers.
First, a helper function used by RPC and GraphQL to make EVM calls without
permanently modifying the account state. `setupComputation` ->
`rpcSetupComputation`.

instead of using header as input param, now getReceipts using
receiptRoot hash, the intention is clearer and less data passed around
when we only using receiptRoot instead of whole block header.
