Replaces #29297, descendant from #27535
---------
This PR removes `locals` as a concept from transaction pools. Therefore,
the pool now acts as very a good simulation/approximation of how our
peers' pools behave. What this PR does instead, is implement a
locals-tracker, which basically is a little thing which, from time to
time, asks the pool "did you forget this transaction?". If it did, the
tracker resubmits it.
If the txpool _had_ forgotten it, chances are that the peers had also
forgotten it. It will be propagated again.
Doing this change means that we can simplify the pool internals, quite a
lot.
### The semantics of `local`
Historically, there has been two features, or usecases, that has been
combined into the concept of `locals`.
1. "I want my local node to remember this transaction indefinitely, and
resubmit to the network occasionally"
2. "I want this (valid) transaction included to be top-prio for my
miner"
This PR splits these features up, let's call it `1: local` and `2:
prio`. The `prio` is not actually individual transaction, but rather a
set of `address`es to prioritize.
The attribute `local` means it will be tracked, and `prio` means it will
be prioritized by miner.
For `local`: anything transaction received via the RPC is marked as
`local`, and tracked by the tracker.
For `prio`: any transactions from this sender is included first, when
building a block. The existing commandline-flag `--txpool.locals` sets
the set of `prio` addresses.

The total difficulty is the sum of all block difficulties from genesis
to a certain block. This value was used in PoW for deciding which chain
is heavier, and thus which chain to select. Since PoS has a different
fork selection algorithm, all blocks since the merge have a difficulty
of 0, and all total difficulties are the same for the past 2 years.
Whilst the TDs are mostly useless nowadays, there was never really a
reason to mess around removing them since they are so tiny. This
reasoning changes when we go down the path of pruned chain history. In
order to reconstruct any TD, we **must** retrieve all the headers from
chain head to genesis and then iterate all the difficulties to compute
the TD.
In a world where we completely prune past chain segments (bodies,
receipts, headers), it is not possible to reconstruct the TD at all. In
a world where we still keep chain headers and prune only the rest,
reconstructing it possible as long as we process (or download) the chain
forward from genesis, but trying to snap sync the head first and
backfill later hits the same issue, the TD becomes impossible to
calculate until genesis is backfilled.
All in all, the TD is a messy out-of-state, out-of-consensus computed
field that is overall useless nowadays, but code relying on it forces
the client into certain modes of operation and prevents other modes or
other optimizations. This PR completely nukes out the TD from the node.
It doesn't compute it, it doesn't operate on it, it's as if it didn't
even exist.
Caveats:
- Whenever we have APIs that return TD (devp2p handshake, tracer, etc.)
we return a TD of 0.
- For era files, we recompute the TD during export time (fairly quick)
to retain the format content.
- It is not possible to "verify" the merge point (i.e. with TD gone, TTD
is useless). Since we're not verifying PoW any more, just blindly trust
it, not verifying but blindly trusting the many year old merge point
seems just the same trust model.
- Our tests still need to be able to generate pre and post merge blocks,
so they need a new way to split the merge without TTD. The PR introduces
a settable ttdBlock field on the consensus object which is used by tests
as the block where originally the TTD happened. This is not needed for
live nodes, we never want to generate old blocks.
- One merge transition consensus test was disabled. With a
non-operational TD, testing how the client reacts to TTD is useless, it
cannot react.
Questions:
- Should we also drop total terminal difficulty from the genesis json?
It's a number we cannot react on any more, so maybe it would be cleaner
to get rid of even more concepts.

This PR modifies how the metrics library handles `Enabled`: previously,
the package `init` decided whether to serve real metrics or just
dummy-types.
This has several drawbacks:
- During pkg init, we need to determine whether metrics are enabled or
not. So we first hacked in a check if certain geth-specific
commandline-flags were enabled. Then we added a similar check for
geth-env-vars. Then we almost added a very elaborate check for
toml-config-file, plus toml parsing.
- Using "real" types and dummy types interchangeably means that
everything is hidden behind interfaces. This has a performance penalty,
and also it just adds a lot of code.
This PR removes the interface stuff, uses concrete types, and allows for
the setting of Enabled to happen later. It is still assumed that
`metrics.Enable()` is invoked early on.
The somewhat 'heavy' operations, such as ticking meters and exp-decay,
now checks the enable-flag to prevent resource leak.
The change may be large, but it's mostly pretty trivial, and from the
last time I gutted the metrics, I ensured that we have fairly good test
coverage.

Lots of packages depend on eth/downloader just for the SyncMode type.
Since we have a dedicated package for eth protocol configuration, it
makes more sense to define SyncMode there, turning eth/downloader into
more of a leaf package.
* eth: drop support for forward sync triggers and head block packets
* consensus, eth: enforce always merged network
* eth: fix tx looper startup and shutdown
* cmd, core: fix some tests
* core: remove notion of future blocks
* core, eth: drop unused methods and types
* eth: make transaction propagation paths in the network deterministic
* eth: avoid potential division by 0
* eth: make tx propagation dependent on local node id too
* eth: fix review comments
* eth: enforce announcement metadatas and drop peers violating the protocol
* eth/fetcher: relax eth/68 validation a bit for flakey clients
* tests/fuzzers/txfetcher: pull in suggestion from Marius
* eth/fetcher: add tests for peer dropping
* eth/fetcher: linter linter linter linter linter
This changes the forkID calculation to ignore time-based forks that occurred before the
genesis block. It's supposed to be done this way because the spec says:
> If a chain is configured to start with a non-Frontier ruleset already in its genesis, that is NOT considered a fork.
This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way
of keeping the blob sidecar within types.Transaction. It's better this way because most
code in go-ethereum does not care about blob transactions, and probably never will. This
will start mattering especially on the client side of RPC, where all APIs are based on
types.Transaction. Users need to be able to use the same signing flows they already
have.
However, since blobs are only allowed in some places but not others, we will now need to
add checks to avoid creating invalid blocks. I'm still trying to figure out the best place
to do some of these. The way I have it currently is as follows:
- In block validation (import), txs are verified not to have a blob sidecar.
- In miner, we strip off the sidecar when committing the transaction into the block.
- In TxPool validation, txs must have a sidecar to be added into the blobpool.
- Note there is a special case here: when transactions are re-added because of a chain
reorg, we cannot use the transactions gathered from the old chain blocks as-is,
because they will be missing their blobs. This was previously handled by storing the
blobs into the 'blobpool limbo'. The code has now changed to store the full
transaction in the limbo instead, but it might be confusing for code readers why we're
not simply adding the types.Transaction we already have.
Code changes summary:
- txpool.Transaction removed and all uses replaced by types.Transaction again
- blobpool now stores types.Transaction instead of defining its own blobTx format for storage
- the blobpool limbo now stores types.Transaction instead of storing only the blobs
- checks to validate the presence/absence of the blob sidecar added in certain critical places
