Reusing state between benchmark iterations resulted in inconsistent
results across runs, which surfaced in https://github.com/ethereum/go-ethereum/issues/30778 .
If these errors are triggered again, they will now trigger panic.

This reverts commit 23800122b3.
The original pull request introduces a bug and some flaky tests are
detected because of this flaw.

Before the original PR, the snapshot would block the function until the
disk layer
was fully generated under the following conditions:
(a) explicitly required by users with `AsyncBuild = false`.
(b) the snapshot was being fully rebuilt or *the disk layer generation
had resumed*.
Unfortunately, with the changes introduced in that PR, the snapshot no
longer waits
for disk layer generation to complete if the generation is resumed. It
brings lots of
uncertainty and breaks this tiny debug feature.
This updates the message you get when trying to initialize Geth with
genesis.json that doesn't have `terminalTotalDifficulty`. The previous
message was a bit obscure, I had to check the code to find out what the
problem was.
This PR is purely for improved readability; I was doing work involving
the file and think this may help others who are trying to understand
what's going on.
1. `snapshot.Tree.Rebuild()` now returns a function that blocks until
regeneration is complete, allowing `Tree.waitBuild()` to be removed
entirely as all it did was search for the `done` channel behind this new
function.
2. Its usage inside `New()` is also simplified by (a) only waiting if
`!AsyncBuild`; and (b) avoiding the double negative of `if !NoBuild`.

#28764 updated `func MakeTopics` to support negative `*big.Int`s.
However, it also changed the behavior of the function from just
_reading_ the input `*big.Int` via `Bytes()`, to leveraging
`big.U256Bytes` which is documented as being _destructive_:
This change updates `MakeTopics` to not mutate the original, and
also applies the same change in signer/core/apitypes.
This PR improves the output of the markdown logger a bit.
- Remove `RStack` field,
- Move `Stack` last, since it may have very large vertical expansion
- Make the pre- and post-exec metadata structured into a bullet-list
This change fixes a bug on the `DirectoryFlag` and the `BigFlag`, which would trigger a `panic` with the message "flag redefined" in case an alias was added to such a flag.
This pull request removes the destruct flag from the state snapshot to
simplify the code.
Previously, this flag indicated that an account was removed during a
state transition, making all associated storage slots inaccessible.
Because storage deletion can involve a large number of slots, the actual
deletion is deferred until the end of the process, where it is handled
in batches.
With the deprecation of self-destruct in the Cancun fork, storage
deletions are no longer expected. Historically, the largest storage
deletion event in Ethereum was around 15 megabytes—manageable in memory.
In this pull request, the single destruct flag is replaced by a set of
deletion markers for individual storage slots. Each deleted storage slot
will now appear in the Storage set with a nil value.
This change will simplify a lot logics, such as storage accessing,
storage flushing, storage iteration and so on.
This pull request refactors the EVM constructor by removing the
TxContext parameter.
The EVM object is frequently overused. Ideally, only a single EVM
instance should be created and reused throughout the entire state
transition of a block, with the transaction context switched as needed
by calling evm.SetTxContext.
Unfortunately, in some parts of the code, the EVM object is repeatedly
created, resulting in unnecessary complexity. This pull request is the
first step towards gradually improving and simplifying this setup.

In many cases, there is a need to create somewhat nontrivial bytecode. A
recent example is the verkle statetests, where we want a `CREATE2`- op
to create a contract, which can then be invoked, and when invoked does a
selfdestruct-to-self.
It is overkill to go full solidity, but it is also a bit tricky do
assemble this by concatenating bytes. This PR takes an approach that
has been used in in goevmlab for several years.
Using this utility, the case can be expressed as:
```golang
// Some runtime code
runtime := program.New().Ops(vm.ADDRESS, vm.SELFDESTRUCT).Bytecode()
// A constructor returning the runtime code
initcode := program.New().ReturnData(runtime).Bytecode()
// A factory invoking the constructor
outer := program.New().Create2AndCall(initcode, nil).Bytecode()
```
We have a lot of places in the codebase where we concatenate bytes, cast
from `vm.OpCode` . By taking tihs approach instead, thos places can be made a
bit more maintainable/robust.
This adds an API method `DropTransactions` to legacy pool, blob pool and
txpool interface. This method removes all txs currently tracked in the
pools.
It modifies the simulated beacon to use the new method in `Rollback`
which removes previous hacky implementation that also erroneously reset
the gas tip to 1 gwei.

The [kilic](https://github.com/kilic/bls12-381) bls12381 implementation
has been archived. It shouldn't be necessary to include it as a fuzzing
target any longer.
This also adds fuzzers for G1/G2 mul that use inputs that are guaranteed
to be valid. Previously, we just did random input fuzzing for these
precompiles.
