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.
Here we add a Go API for running tracing plugins within the main block import process.
As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within
that file register your custom tracer implementation. Then recompile geth and select your tracer
on the command line. Hooks defined in the tracer will run whenever a block is processed.
The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of
requiring an interface, for several reasons:
- We plan to keep this API stable long-term. The core/tracing hook API does not depend on
on deep geth internals.
- There are a lot of hooks, and tracers will only need some of them. Using a struct allows you
to implement only the hooks you want to actually use.
All existing tracers in eth/tracers/native have been rewritten to use the new hook system.
This change breaks compatibility with the vm.EVMLogger interface that we used to have.
If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking
your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM.

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.
The code to compute a versioned hash was duplicated a couple times, and also had a small
issue: if we ever change params.BlobTxHashVersion, it will most likely also cause changes
to the actual hash computation. So it's a bit useless to have this constant in params.
EIP-4844 adds a new transaction type for blobs. Users can submit such transactions via `eth_sendRawTransaction`. In this PR we refrain from adding support to `eth_sendTransaction` and in fact it will fail if the user passes in a blob hash.
However since the chain can handle such transactions it makes sense to allow simulating them. E.g. an L2 operator should be able to simulate submitting a rollup blob and updating the L2 state. Most methods that take in a transaction object should recognize blobs. The change boils down to adding `blobVersionedHashes` and `maxFeePerBlobGas` to `TransactionArgs`. In summary:
- `eth_sendTransaction`: will fail for blob txes
- `eth_signTransaction`: will fail for blob txes
The methods that sign txes does not, as of this PR, add support the for new EIP-4844 transaction types. Resuming the summary:
- `eth_sendRawTransaction`: can send blob txes
- `eth_fillTransaction`: will fill in a blob tx. Note: here we simply fill in normal transaction fields + possibly `maxFeePerBlobGas` when blobs are present. One can imagine a more elaborate set-up where users can submit blobs themselves and we fill in proofs and commitments and such. Left for future PRs if desired.
- `eth_call`: can simulate blob messages
- `eth_estimateGas`: blobs have no effect here. They have a separate unit of gas which is not tunable in the transaction.

This PR unifies the error handling in miner.
Whenever an error occur while applying a transaction, the transaction should be regarded as invalid and all following transactions from the same sender not executable because of the nonce restriction. The only exception is the `nonceTooLow` error which is handled separately.
This PR removes the Debug field from vmconfig, making it so that if a tracer is set, debug=true is implied.

Here, the core.Message interface turns into a plain struct and
types.Message gets removed.
This is a breaking change to packages core and core/types. While we do
not promise API stability for package core, we do for core/types. An
exception can be made for types.Message, since it doesn't have any
purpose apart from invoking the state transition in package core.
types.Message was also marked deprecated by the same commit it
got added in, 4dca5d4db7 (November 2016).
The core.Message interface was added in December 2014, in commit
db494170dc, for the purpose of 'testing' state transitions. It's the
same change that made transaction struct fields private. Before that,
the state transition used *types.Transaction directly.
Over time, multiple implementations of the interface accrued across
different packages, since constructing a Message is required whenever
one wants to invoke the state transition. These implementations all
looked very similar, a struct with private fields exposing the fields
as accessor methods.
By changing Message into a struct with public fields we can remove all
these useless interface implementations. It will also hopefully
simplify future changes to the type with less updates to apply across
all of go-ethereum when a field is added to Message.

A comment suggests that contract creation happens if the recipient of a call is 0x00..00 ("zero address") but in fact the sender must be nil. The zero address is a regular valid address that is commonly used as a "burn" address.
This changes the CI / release builds to use the latest Go version. It also
upgrades golangci-lint to a newer version compatible with Go 1.19.
In Go 1.19, godoc has gained official support for links and lists. The
syntax for code blocks in doc comments has changed and now requires a
leading tab character. gofmt adapts comments to the new syntax
automatically, so there are a lot of comment re-formatting changes in this
PR. We need to apply the new format in order to pass the CI lint stage with
Go 1.19.
With the linter upgrade, I have decided to disable 'gosec' - it produces
too many false-positive warnings. The 'deadcode' and 'varcheck' linters
have also been removed because golangci-lint warns about them being
unmaintained. 'unused' provides similar coverage and we already have it
enabled, so we don't lose much with this change.
During RPC calls such as eth_call and eth_estimateGas, st.evm.Config.NoBaseFee is set
which allows the gas price to be below the base fee. This results the tip being negative,
and balance being subtracted from the coinbase instead of added to it, which results in a
potentially negative coinbase balance interestingly. This can't happen during normal chain
processing as outside of RPC calls the gas price is required to be at least the base fee,
as NoBaseFee is false.
This change prevents this behavior by disabling fee payment when the fee is not set.

This adds a check to verify that a sender-account does not have code, which means that the codehash is either `emptyCodeHash` _OR_ not present. The latter occurs IFF the sender did not previously exist, a situation which can only occur with zero cost gasprices.
When processing a transaction with London fork rules, EIP-1559 mandates
checking that the sender must have sufficient balance to cover gas * gasFeeCap.
In the EIP's pseudocode, this check happens after the value transferred by the
transaction has already been deducted. However, in go-ethereum, the balance
has not yet been updated when the check happens, and therefore needs to be
added explicitly.
