In legacy (pre-merge) sync mode, headers were contiguously downloaded from the network and when no more headers were available, we checked every few seconds whether there are 64 new blocks to move the pivot.

In beacon (post-merge) sync mode, we don't need to check for new skeleton headers non stop, since those re delivered one by one by the engine API. The missing code snippet from the header fetcher was to actually look at the latest head and move the pivot if it was more than 2*64-8 away. This PR adds the missing movement logic.

This makes non-JS tracers execute all block txs on a single goroutine.
In the previous implementation, we used to prepare every tx pre-state
on one goroutine, and then run the transactions again with tracing enabled.
Native tracers are usually faster, so it is faster overall to use their output as
the pre-state for tracing the next transaction.

This PR removes the notion of fakeStorage from the state objects, and instead, for any state modifications that are needed, it simply makes the changes.

* p2p/discover: add more packet information in logs

This adds more fields to discv5 packet logs. These can be useful when
debugging multi-packet interactions.

The FINDNODE message also gets an additional field, OpID for debugging
purposes. This field is not encoded onto the wire.

I'm also removing topic system related message types in this change.
These will come back in the future, where support for them will be
guarded by a config flag.

* p2p/discover/v5wire: rename 'Total' to 'RespCount'

The new name captures the meaning of this field better.

Alarm is a timer utility that simplifies code where a timer needs to be rescheduled over
and over. Doing this can be tricky with time.Timer or time.AfterFunc because the channel
requires draining in some cases.

Alarm is optimized for use cases where items are tracked in a heap according to their expiry
time, and a goroutine with a for/select loop wants to be woken up whenever the next item expires.
In this application, the timer needs to be rescheduled when an item is added or removed
from the heap. Using a timer naively, these updates will always require synchronization
with the global runtime timer datastructure to update the timer using Reset. Alarm avoids
this by tracking the next expiry time and only modifies the timer if it would need to fire earlier
than already scheduled.

As an example use, I have converted p2p.dialScheduler to use Alarm instead of AfterFunc.

This change sends a HeadChainEvent when SetHead is invoked. The txpool will then reset the txnoncer on receiving the event. 

This changes moves the tracking of "deleted in this block" out from snap-only domain, so that it happens regardless of whether the execution is snapshot-backed or trie-backed.

This changes the StorageTrie method to return an error when the trie
is not available. It used to return an 'empty trie' in this case, but that's
not possible anymore under PBSS.

This PR builds on #26299, but also updates the tests to the most recent version, which includes tests regarding TheMerge.

This change adds checks to the beacon consensus engine, making it more strict in validating the pre- and post-headers, and not relying on the caller to have already correctly sanitized the headers/blocks. 

This PR implements resettable freezer by adding a ResettableFreezer wrapper.

The resettable freezer wraps the original freezer in a way that makes it possible to ensure atomic resets. Implementation wise, it relies on the os.Rename and os.RemoveAll to atomically delete the original freezer data and re-create a new one from scratch. 

This PR fixes an error in trie commit. If the trie.root is nil, it can be two possible scenarios:

-  The trie was empty, and no change happens
-  The trie was non-empty and all nodes are dropped

For the latter one, we should collect the deletions and apply them into database(e.g. in PBSS).

This ensures that RPC method handlers will react to a timeout or
cancelled request soon after the event occurs.

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.
