This is a PR that removes all correctly flagged typos, in order to stop
an onslaught of slop PRs in its tracks. It should be followed by #34994
but the latter needs more configuration work and I want to limit the
stem of PRs right now.
This PR finally lands EIP-7928, collecting the block accessList during
the block execution and verifying against the block header.

EIP-7825 caps the transaction gas limit at `MaxTxGas`, but after
Amsterdam/EIP-8037 the transaction gas limit can include state gas
reservoir in addition to the regular gas dimension. Applying the Osaka
cap to the full `tx.Gas()` rejects otherwise valid Amsterdam
transactions that need more than `MaxTxGas` total gas because of state
gas, while their regular gas use remains within the intended limit.
This changes geth to stop applying the full transaction gas cap once
Amsterdam is active:
- txpool stateless validation no longer rejects `tx.Gas() > MaxTxGas`
under Amsterdam
- legacy pool reorg cleanup does not purge high-total-gas transactions
at the Osaka transition if Amsterdam is also active
- execution precheck mirrors the txpool behavior and does not reject
high-total-gas messages under Amsterdam
The block gas limit check remains in place, so transactions still cannot
request more total gas than the current block gas limit.
Validation run:
```
go test ./core/txpool ./core/txpool/legacypool
go test ./core -run TestStateProcessorErrors
```

This PR introduces a gasBudget struct to track the available gas for EVM
execution.
With the upcoming EIP-8037, multi-dimensional gas accounting will be
introduced, requiring multiple gas budget counters to be tracked
simultaneously. To support this, the counters are grouped into a gasBudget
structure.
This change is a prerequisite for internal refactoring in preparation
for EIP-8037.

This PR fixes https://github.com/ethereum/go-ethereum/issues/34623 by
changing the `vm.StateDB` interface:
Instead of `EmitLogsForBurnAccounts()` emitting burn logs, `LogsForBurnAccounts()
[]*types.Log` just returns these logs which are then emitted by the caller.
This way when tracing is used, `hookedStateDB.AddLog` will be used
automatically and there is no need to duplicate either the burn log
logic or the `OnLog` tracing hook.

This disables the tx gaslimit cap for eth_call and related RPC operations.
I don't like how this fix works. Ideally we'd be checking the tx
gaslimit somewhere else, like in the block validator, or any other place
that considers block transactions. Doing the check in StateTransition
means it affects all possible ways of executing a message.
The challenge is finding a place for this check that also triggers
correctly in tests where it is wanted. So for now, we are just combining
this with the EOA sender check for transactions. Both are disabled for
call-type messages.
[EIP-7594](https://eips.ethereum.org/EIPS/eip-7594) defines a limit of
max 6 blobs per transaction. We need to enforce this limit during block
processing.
> Additionally, a limit of 6 blobs per transaction is introduced.
Clients MUST enforce this limit when validating blob transactions at
submission time, when received from the network, and during block
production and processing.
Since we have the effective gas price in the message, we can compute tip by
simply subtracting the basefee. No need to recompute the effective price.

Adding values to the witness introduces a new class of issues for
computing gas: if there is not enough gas to cover adding an item to the
witness, then the item should not be added to the witness.
The problem happens when several items are added together, and that
process runs out of gas. The witness gas computation needs a way to
signal that not enough gas was provided. These values can not be
hardcoded, however, as they are context dependent, i.e. two calls to the
same function with the same parameters can give two different results.
The approach is to return both the gas that was actually consumed, and
the gas that was necessary. If the values don't match, then a witness
update OOG'd. The caller should then charge the `consumed` value
(remaining gas will be 0) and error out.
Why not return a boolean instead of the wanted value? Because when
several items are touched, we want to distinguish which item lacked gas.

This pull request enhances the block prefetcher by executing transactions
in parallel to warm the cache alongside the main block processor.
Unlike the original prefetcher, which only executes the next block and
is limited to chain syncing, the new implementation can be applied to any
block. This makes it useful not only during chain sync but also for regular
block insertion after the initial sync.

This PR does a few things including:
- Remove `ContractRef` interface
- Remove `vm.AccountRef` which implements `ContractRef` interface
- Maintain the `jumpDests` struct in EVM for sharing between call frames
- Simplify the delegateCall context initialization
Here we add some more changes for live tracing API v1.1:
- Hook `OnSystemCallStartV2` was introduced with `VMContext` as parameter.
- Hook `OnBlockHashRead` was introduced.
- `GetCodeHash` was added to the state interface
- The new `WrapWithJournal` construction helps with tracking EVM reverts in the tracer.

We still need to decide how to handle non-specfic `chainId` in the JSON
encoding of authorizations. With `chainId` being a uint64, the previous
implementation just used value zero. However, it might actually be more
correct to use the value `null` for this case.
Here I am proposing two small changes to the exported API for EIP-7702:
(1) `Authorization` has a very generic name, but it is in fact only used
for one niche use case: authorizing code in a `SetCodeTx`. So I propose
calling it `SetCodeAuthorization` instead. The signing function is
renamed to `SignSetCode` instead of `SignAuth`.
(2) The signing function for authorizations should take key as the first
parameter, and the authorization second. The key will almost always be
in a variable, while the authorization can be given as a literal.
This PR implements EIP-7702: "Set EOA account code".
Specification: https://eips.ethereum.org/EIPS/eip-7702
> Add a new transaction type that adds a list of `[chain_id, address,
nonce, y_parity, r, s]` authorization tuples. For each tuple, write a
delegation designator `(0xef0100 ++ address)` to the signing account’s
code. All code reading operations must load the code pointed to by the
designator.

This change relocates the EVM tx context switching to the ApplyMessage function.
With this change, we can remove a lot of EVM.SetTxContext calls before
message execution.
### Tracing API changes
- This PR replaces the `GasPrice` field of the `VMContext` struct with
`BaseFee`. Users may instead take the effective gas price from
`tx.EffectiveGasTipValue(env.BaseFee)`.

Way back we've added `common.math.BigMin` and `common.math.BigMax`.
These were kind of cute helpers, but unfortunate ones, because package
all over out codebase added dependencies to this package just to avoid
having to write out 3 lines of code.
Because of this, we've also started having package name clashes with the
stdlib `math`, which got solves even more badly by moving some helpers
over ***from*** the stdlib into our custom lib (e.g. MaxUint64). The
latter ones were nuked out in a previous PR and this PR nukes out BigMin
and BigMax, inlining them at all call sites.
As we're transitioning to uint256, if need be, we can add a min and max
to that.
This is a successor PR to #25743. This PR is based on a new iteration of
the spec: https://github.com/ethereum/execution-apis/pull/484.
`eth_multicall` takes in a list of blocks, each optionally overriding
fields like number, timestamp, etc. of a base block. Each block can
include calls. At each block users can override the state. There are
extra features, such as:
- Include ether transfers as part of the logs
- Overriding precompile codes with evm bytecode
- Redirecting accounts to another address
## Breaking changes
This PR includes the following breaking changes:
- Block override fields of eth_call and debug_traceCall have had the
following fields renamed
- `coinbase` -> `feeRecipient`
- `random` -> `prevRandao`
- `baseFee` -> `baseFeePerGas`

This PR implements changes related to
[EIP-6800](https://eips.ethereum.org/EIPS/eip-6800) and
[EIP-4762](https://eips.ethereum.org/EIPS/eip-4762) spec updates.
A TL;DR of the changes is that `Version`, `Balance`, `Nonce` and
`CodeSize` are encoded in a single leaf named `BasicData`. For more
details, see the [_Header Values_ table in
EIP-6800](https://eips.ethereum.org/EIPS/eip-6800#header-values).
The motivation for this was simplifying access event patterns, reducing
code complexity, and, as a side effect, saving gas since fewer leaf
nodes must be accessed.

It's a bit confusing to add msg.value into the balanceCheck within the conditional.
No impact on block validation since GasFeeCap is always set when processing transactions.
