The code field can be accessed in Solidity for an arbitrary address using `extcodesize`, `extcodehash`, and `extcodecopy` or helper commands (such as `address.code.Length`). The presence of this field is used by contract developers to (erroneously) deny smart contract access to other smart contracts (and therefore, validators). This PR fixes that oversight by returning the same values as other EOAs for known validator addresses. Obviously, it needs a hard fork that will be scheduled separately. * Fix context passing. * Clean up code. * Removed engine dependency. * Fix possible panic. * Clean up code. * Network type. * Fix tests. * Revert "Removed engine dependency."
