refactor chain_config and add decodeNetworkParams
allow custom network not only loaded from file but also
decoded from json string

Jordan Hrycaj 215e9856d3
Jordan/custom network (#962)
* Rearrange/rename test_kintsugu => test_custom_network

why:
  Debug, fix and test more general problems related to running
  nimbus on a custom network.

* Update UInt265/Json parser for --custom-network command line option

why:
  As found out with the Kintsugi configuration, block number and balance
  have the same Nim type which led to misunderstandings. This patch makes
  sure that UInt265 encoded string values "0x11" decodes to 17, and "b"
  and "11" to 11.

* Refactored genesis.toBlock() => genesis.toBlockHeader()

why:
  The function toBlock(g,db) may return different results depending on
  whether the db descriptor argument is nil, or initialised. This is due
  to the db.config data sub-descriptor which may give various outcomes
  for the baseFee field of the genesis header.

  Also, the version where db is non-nil initialised is used internally
  only. So the public rewrite toBlockHeader() that replaces the toBlock()
  function expects a full set of NetworkParams.

* update comments

* Rename toBlockHeader() => toGenesisHeader()

why:
  Polymorphic prototype used for BaseChainDB or NetworkParams argument.
  With a BaseChainDB descriptor argument, the name shall imply that the
  header is generated from the config fields rather than fetched from
  the database.

* Added command line option --static-peers-file

why:
  Handy feature to keep peer nodes in a file, similar to the
  --bootstrap-file option.

Zahary Karadjov 137eb97766 Initial implementation of the merge spec
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:

Arrow Glacier fork
Add the new [Arrow Glacier fork](https://eips.ethereum.org/EIPS/eip-4345).

Only the difficulty calculation is changed, but as a new fork it still affects
a number of places in the code.

To the best of my knowledge the change is only scheduled on Mainnet.

In addition:

- The fork date comments in `chain_config.nim` have been checked against the
  real networks, set consistently in UTC instead of random timezones, and made
  neater.  Maybe we'll keep these when transferring config to a file someday.

- It's added to forkid hash tests (EIP-2124/EIP-2364), of course.

preparation for London hard fork
This preparation is needed for subsequent
EIPs included in London.

- Add London to Fork enum
- Block number to fork
- Parsing London fork in chain config
- Prepare gas costs table for London
- Prepare EVM opcode dispatcher for London
- Block rewards for London
- Prepare hive script for London

drop PublicNetwork enum usage and replace it with NetworkId
we cannot limit the `--networkid` switch to values available in
`PublicNetwork` enum. it should able to accept very wide range of
custom NetworkId.

fixes crappy custom genesis and chain config parser
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
