core/vm: fix incorrect computation of BLS discount (#21253)
* core/vm: fix incorrect computation of discount

During testing on Yolov1 we found that the way geth calculates the discount
is not in line with the specification. Basically what we did is calculate
128 * Bls12381GXMulGas * discount / 1000 whenever we received more than 128 pairs
of values. Correct would be to calculate k * Bls12381... for k > 128.

* core/vm: better logic for discount calculation

* core/vm: better calculation logic, added worstcase benchmarks

all: seperate consensus error and evm internal error (#20830)
* all: seperate consensus error and evm internal error

There are actually two types of error will be returned when
a tranaction/message call is executed: (a) consensus error
(b) evm internal error. The former should be converted to
a consensus issue, e.g. The sender doesn't enough asset to
purchase the gas it specifies. The latter is allowed since
evm itself is a blackbox and internal error is allowed to happen.

This PR emphasizes the difference by introducing a executionResult
structure. The evm error is embedded inside. So if any error
returned, it indicates consensus issue happens.

And also this PR improve the `EstimateGas` API to return the concrete
revert reason if the transaction always fails

core/vm, crypto/blake2b: add BLAKE2b compression func at 0x09
The precompile at 0x09 wraps the BLAKE2b F compression function:
https://tools.ietf.org/html/rfc7693#section-3.2

The precompile requires 6 inputs tightly encoded, taking exactly 213
bytes, as explained below.

- `rounds` - the number of rounds - 32-bit unsigned big-endian word
- `h` - the state vector - 8 unsigned 64-bit little-endian words
- `m` - the message block vector - 16 unsigned 64-bit little-endian words
- `t_0, t_1` - offset counters - 2 unsigned 64-bit little-endian words
- `f` - the final block indicator flag - 8-bit word

[4 bytes for rounds][64 bytes for h][128 bytes for m][8 bytes for t_0]
[8 bytes for t_1][1 byte for f]

The boolean `f` parameter is considered as `true` if set to `1`.
The boolean `f` parameter is considered as `false` if set to `0`.
All other values yield an invalid encoding of `f` error.

The precompile should compute the F function as specified in the RFC
(https://tools.ietf.org/html/rfc7693#section-3.2) and return the updated
state vector `h` with unchanged encoding (little-endian).

See EIP-152 for details.

beff5fa578 params, core/vm: Istanbul EIP-1108 bn256 gas cost reduction (#19904)
* params: add IsIstanbul to config + rules

IstanbulBlock, used to determine if the config IsIstanbul, is currently
left nil until an actual block is chosen.

* params, core/vm: implement EIP-1108

Old gas costs for elliptic curve operations are given the PreIstanbul
prefix, while current gas costs retain the unprefixed names. The actual
precompile implementations are the same, so they are factored out into
common functions that are called by the pre-Istanbul and current
precompile structs. Finally, an Istanbul precompile list is added that
references the new precompile structs, which in turn reference the new
gas costs.

core/vm: instruction tests (#16327)
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.

ecb781297b 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!

4c0883e20d core/vm: adds refund as part of the json standard trace (#17910)
This adds the global accumulated refund counter to the standard

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.

ae992a5d73 core/vm: Hide read only flag from Interpreter interface (#17461)
Makes Interface interface a bit more stateless and abstract.

Obviously this change is dictated by EVMC design. The EVMC tries to keep the responsibility for EVM features totally inside the VMs, if feasible. This makes VM "stateless" because VM does not need to pass any information between executions, all information is included in parameters of the execute function.

32f28a9360 core/vm, tests: update tests, enable constantinople statetests, fix SAR opcode (#17538)
This commit does a few things at once:

- Updates the tests to contain the latest data from ethereum/tests repo.
- Enables Constantinople state tests. This is needed to be able to
  fuzz-test the evm with constantinople rules.
- Fixes the error in opSAR that we've known about for some time. I was
  kind of saving it to see if we hit upon it with the random test
  generator, but it's difficult to both enable the tests and have the
  bug there -- we don't want to forget about it, so maybe it's better
  to just fix it.
