This pull request delivers the new version of the state history, where
the raw storage key is used instead of the hash.
Before the cancun fork, it's supported by protocol to destruct a
specific account and therefore, all the storage slot owned by it should
be wiped in the same transition.
Technically, storage wiping should be performed through storage
iteration, and only the storage key hash will be available for traversal
if the state snapshot is not available. Therefore, the storage key hash
is chosen as the identifier in the old version state history.
Fortunately, account self-destruction has been deprecated by the
protocol since the Cancun fork, and there are no empty accounts eligible
for deletion under EIP-158. Therefore, we can conclude that no storage
wiping should occur after the Cancun fork. In this case, it makes no
sense to keep using hash.
Besides, another big reason for making this change is the current format
state history is unusable if verkle is activated. Verkle tree has a
different key derivation scheme (merkle uses keccak256), the preimage of
key hash must be provided in order to make verkle rollback functional.
This pull request is a prerequisite for landing verkle.
Additionally, the raw storage key is more human-friendly for those who
want to manually check the history, even though Solidity already
performs some hashing to derive the storage location.

This pull request doesn't bump the database version, as I believe the
database should still be compatible if users degrade from the new geth
version to old one, the only side effect is the persistent new version
state history will be unusable.

This pull request ports some changes from the main state snapshot
integration one, specifically introducing the flat state tracking in
pathdb.
Note, the tracked flat state changes are only held in memory and won't
be persisted in the disk. Meanwhile, the correspoding state retrieval in
persistent state is also not supported yet. The states management in
disk is more complicated and will be implemented in a separate pull
request.
Part 1: https://github.com/ethereum/go-ethereum/pull/30752
This PR fixes some issues with benchmarks
- [x] Removes log output from a log-test
- [x] Avoids a `nil`-defer in `triedb/pathdb`
- [x] Fixes some crashes re tracers
- [x] Refactors a very resource-expensive benchmark for blobpol.
**NOTE**: this rewrite touches live production code (a little bit), as
it makes the validator-function used by the blobpool configurable.
- [x] Switch some benches over to use pebble over leveldb
- [x] reduce mem overhead in the setup-phase of some tests
- [x] Marks some tests with a long setup-phase to be skipped if `-short`
is specified (where long is on the order of tens of seconds). Ideally,
in my opinion, one should be able to run with `-benchtime 10ms -short`
and sanity-check all tests very quickly.
- [x] Drops some metrics-bechmark which times the speed of `copy`.
