core, cmd/puppeth: implement constantinople fix, disable EIP-1283 ( #18486 )
...
This PR adds a new fork which disables EIP-1283. Internally it's called Petersburg,
but the genesis/config field is ConstantinopleFix.
The block numbers are:
7280000 for Constantinople on Mainnet
7280000 for ConstantinopleFix on Mainnet
4939394 for ConstantinopleFix on Ropsten
9999999 for ConstantinopleFix on Rinkeby (real number decided later)
This PR also defaults to using the same ConstantinopleFix number as whatever
Constantinople is set to. That is, it will default to mainnet behaviour if ConstantinopleFix
is not set.This means that for private networks which have already transitioned
to Constantinople, this PR will break the network unless ConstantinopleFix is
explicitly set!

core/vm: adds refund as part of the json standard trace ( #17910 )
...
This adds the global accumulated refund counter to the standard
json output as a numeric json value. Previously this was not very
interesting since it was not used much, but with the new sstore
gas changes the value is a lot more interesting from a consensus
investigation perspective.
