This change makes use of uin256 to represent balance in state. It touches primarily upon statedb, stateobject and state processing, trying to avoid changes in transaction pools, core types, rpc and tracers.
This PR moves our fuzzers from tests/fuzzers into whatever their respective 'native' package is.
The historical reason why they were placed in an external location, is that when they were based on go-fuzz, they could not be "hidden" via the _test.go prefix. So in order to shove them away from the go-ethereum "production code", they were put aside.
But now we've rewritten them to be based on golang testing, and thus can be brought back. I've left (in tests/) the ones that are not production (bls128381), require non-standard imports (secp requires btcec, bn256 requires gnark/google/cloudflare deps).
This PR also adds a fuzzer for precompiled contracts, because why not.
This PR utilizes a newly rewritten replacement for go-118-fuzz-build, namely gofuzz-shim, which utilises the inputs from the fuzzing engine better.
* core/vm: set basefee to 0 internally on eth_call
* core: nicer 0-basefee, make it work for blob fees too
* internal/ethapi: make tests a bit more complex
* core: fix blob fee checker
* core: make code a bit more readable
* core: fix some test error strings
* core/vm: Get rid of weird comment
* core: dict wrong typo

This updates the reference tests to the latest version and also adds logic
to process EIP-4844 blob transactions into the state transition. We are now
passing most Cancun fork tests.

The EIP150Hash was an idea where, after the fork, we hardcoded the forked hash as an extra defensive mechanism. It wasn't really used, since forks weren't contentious and for all the various testnets and private networks it's been a hassle to have around.
This change removes that config field.

This PR removes the Debug field from vmconfig, making it so that if a tracer is set, debug=true is implied.

When interacting with geth as a library to e.g. produce state tests, it is desirable to obtain the consensus-correct jumptable definition for a given fork. This changes adds accessors so the instructionset can be obtained and characteristics about opcodes can be inspected.
This is a breaking change in the tracing hooks API as well as semantics of the callTracer:
- CaptureEnter hook provided a nil value argument in case of DELEGATECALL. However to stay consistent with how delegate calls behave in EVM this hook is changed to pass in the value of the parent call.
- callTracer will return parent call's value for DELEGATECALL frames.

This change improves reusability of the EVM struct. Two methods are added:
- SetBlockContext(...)
- SetTracer(...)
Other attributes like the TransactionContext and the StateDB can already be updated.
BlockContext and Tracer are partially not updateable right now. This change fixes it and
opens the potential to reuse an EVM struct in more ways.

This PR changes the API so that uint64 is used for fork timestamps.
It's a good choice because types.Header also uses uint64 for time.

This makes non-JS tracers execute all block txs on a single goroutine.
In the previous implementation, we used to prepare every tx pre-state
on one goroutine, and then run the transactions again with tracing enabled.
Native tracers are usually faster, so it is faster overall to use their output as
the pre-state for tracing the next transaction.

This removes the 'time' field from logs, as well as from the tracer interface. This change makes the trace output deterministic. If a tracer needs the time they can measure it themselves. No need for evm to do this.
