This is a rewrite of the 'simulated backend', an implementation of the ethclient interfaces
which is backed by a simulated blockchain. It was getting annoying to maintain the old
version of the simulated backend feature because there was a lot of code duplication with
the main client.
The new version is built using parts that we already have: an in-memory geth node instance
running in developer mode provides the chain, while the Go API is provided by ethclient.
A backwards-compatibility wrapper is provided, but the simulated backend has also moved to
a more sensible import path: github.com/ethereum/go-ethereum/ethclient/simulated

When managing geth, it is sometimes desirable to do a partial wipe; deleting state but retaining freezer data. A partial wipe can be somewhat tricky to accomplish.
This change implements the ability to perform partial wipe by making it possible to run geth removedb non-interactive, using command line options instead.
This PR will allow a previously underpriced transaction back in after a timeout
of 5 minutes. This will block most transaction spam but allow for transactions to
be re-broadcasted on networks with less transaction flow.

# Conflicts:
# eth/fetcher/tx_fetcher.go
This is a minor refactor in preparation of changes to range verifier. This PR contains no intentional functional changes but moves (and renames) the light.NodeSet
* cmd, les, tests: remove light client code
This commit removes the light client (LES) code.
Since the merge the light client has been broken and
it is hard to maintain it alongside the normal client.
We decided it would be best to remove it for now and
maybe rework and reintroduce it in the future.
* cmd, eth: remove some more mentions of light mode
* cmd: re-add flags and mark as deprecated
* cmd: warn the user about deprecated flags
* eth: better error message
* triedb/pathdb: fix async node buffer diskroot mismatches when journaling
* triedb: check whether the async flush is done
* fix: generate new eth config

This pull request improves the condition to check if path state scheme is in use.
Originally, root node presence was used as the indicator if path scheme is used or not. However due to fact that root node will be deleted during the initial snap sync, this condition is no longer useful.
If PersistentStateID is present, it shows that we've already configured for path scheme.
Original problem was caused by #28595, where we made it so that as soon as we start to sync, the root of the disk layer is deleted. That is not wrong per se, but another part of the code uses the "presence of the root" as an init-check for the pathdb. And, since the init-check now failed, the code tried to re-initialize it which failed since a sync was already ongoing.
The total impact being: after a state-sync has begun, if the node for some reason is is shut down, it will refuse to start up again, with the error message: `Fatal: Failed to register the Ethereum service: waiting for sync.`.
This change also modifies how `geth removedb` works, so that the user is prompted for two things: `state data` and `ancient chain`. The former includes both the chaindb aswell as any state history stored in ancients.
