Added a start/end system where tracer can be notified that processing of some Ethereum system calls is starting processing and also notifies it when the processing has completed.
Doing a start/end for system call will enable tracers to "route" incoming next tracing events to go to a separate bucket than other EVM calls. Those not interested by this fact can simply avoid registering the hooks.
The EVM call is going to be traced normally afterward between the signals provided by those 2 new hooks but outside of a transaction context OnTxStart/End. That something implementors of live tracers will need to be aware of (since only "trx tracers" are not concerned by ProcessBeaconRoot).

This PR fixes some flaws with the existing tests.
The randomized testing (TestSnapshotRandom) executes a series of steps which modify the state and create journal-events. Later on, we compare the forward-going-states against the backwards-unrolling-journal-states, and check that they are identical.
The "identical" check is performed using various accessors. It turned out that we failed to check some things:
- the accesslist contents
- the transient storage contents
- the 'newContract' flag
- the dirty storage map
This change adds these new checks
Currently our state journal tracks each storage update to a contract, having the ability to revert those changes to the previously set value.
For the very first modification however, it behaves a bit wonky. Reverting the update doesn't actually remove the dirty-ness of the slot, rather leaves it as "change this slot to it's original value". This can cause issues down the line with for example write witnesses needing to gather an unneeded proof.
This PR modifies the storageChange journal entry to not only track the previous value of a slot, but also whether there was any previous value at all set in the current execution context. In essence, the PR changes the semantic of storageChange so it does not simply track storage changes, rather it tracks dirty storage changes, an important distinction for being able to cleanly revert the journal item.
This PR updates the bls contracts from our internal implementation which is an unmaintained fork of the kilic library to the gnark-crypto library that is actively maintained by consensys.
It also updates the gas-costs according to the EIP
This pull request defines a gentrie for snap sync purpose.
The stackTrie is used to generate the merkle tree nodes upon receiving a state batch. Several additional options have been added into stackTrie to handle incomplete states (either missing states before or after).
In this pull request, these options have been relocated from stackTrie to genTrie, which serves as a wrapper for stackTrie specifically for snap sync purposes.
Further, the logic for managing incomplete state has been enhanced in this change. Originally, there are two cases handled:
- boundary node filtering
- internal (covered by extension node) node clearing
This changes adds one more:
- Clearing leftover nodes on the boundaries.
This feature is necessary if there are leftover trie nodes in database, otherwise node inconsistency may break the state healing.
time.After is equivalent to NewTimer(d).C, and does not call Stop if the timer is no longer needed. This can cause memory leaks. This change changes many such occations to use NewTimer instead, and calling Stop once the timer is no longer needed.
