This PR fixes a flaky jwt-test.
The test is a jwt "from one second in the future". The test passes; the
reason for this is that the CI-system is slow, and by the time the jwt
is actually evaluated, that second has passed, and it's no longer
future.
Alternative to #30380
This PR changes how sidechains are handled.
Before the merge, it was possible to import a chain with lower td and not set it as canonical. After the merge, we expect every chain that we get via InsertChain to be canonical. Non-canonical blocks can still be inserted
with InsertBlockWIthoutSetHead.
If during the InsertChain, the existing chain is not canonical anymore, we mark it as a sidechain and send the SideChainEvents normally.
This pull request fixes a flaw in prefetcher.
In verkle tree world, both accounts and storage slots are committed into
a single tree instance for state hashing. If the prefetcher is activated, we will
try to pull the trie for the prefetcher for performance speedup.
However, we had a special logic to skip pulling storage trie if the
storage root is empty. While it's true for merkle as we have nothing to
do with an empty storage trie, it's totally wrong for verkle. The consequences
for skipping pulling is the storage changes are committed into trie A, while the
account changes are committed into trie B (pulled from the prefetcher), boom.
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.

This PR adds the bulk verkle witness+proof production at the end of block
production. It reads all data from the tree in one swoop and produces
a verkle proof.

When attempting to hash a typed data struct that includes a type
reference with a fixed-size array, the validation process fails.
According to EIP-712, arrays can be either fixed-size or dynamic,
denoted by `Type[n]` or `Type[]` respectively, although it appears this
currently isn't supported.
This change modifies the validation logic to accommodate types
containing fixed-size arrays.
This is a follow-up to #29520, and a preparatory PR to a more thorough
change in the journalling system.
### API methods instead of `append` operations
This PR hides the journal-implementation details away, so that the
statedb invokes methods like `JournalCreate`, instead of explicitly
appending journal-events in a list. This means that it's up to the
journal whether to implement it as a sequence of events or
aggregate/merge events.
### Snapshot-management inside the journal
This PR also makes it so that management of valid snapshots is moved
inside the journal, exposed via the methods `Snapshot() int` and
`RevertToSnapshot(revid int, s *StateDB)`.
### SetCode
JournalSetCode journals the setting of code: it is implicit that the
previous values were "no code" and emptyCodeHash. Therefore, we can
simplify the setCode journal.
### Selfdestruct
The self-destruct journalling is a bit strange: we allow the
selfdestruct operation to be journalled several times. This makes it so
that we also are forced to store whether the account was already
destructed.
What we can do instead, is to only journal the first destruction, and
after that only journal balance-changes, but not journal the
selfdestruct itself.
This simplifies the journalling, so that internals about state
management does not leak into the journal-API.
### Preimages
Preimages were, for some reason, integrated into the journal management,
despite not being a consensus-critical data structure. This PR undoes
that.

In few tests the returned error from `SendTransaction` is not being
checked. This PR checks the returned err in tests.
Returning errors also revealed tx in `TestCommitReturnValue` is not
actually being sent, and returns err ` only replay-protected (EIP-155)
transactions allowed over RPC`. Fixed the transaction by using the
`testTx` function.
`WriteToUDP` was never called, since `meteredUdpConn` exposed directly
all the methods from the underlying `UDPConn` interface.
This fixes the `discover/egress` metric never being updated.
This pull request adds a few more performance metrics, specifically:
- The average time cost of an account read
- The average time cost of a storage read
- The rate of account reads
- The rate of storage reads
