This fixes 2 related issues:
* Now that the bor consensus engine is required for queries it can't be
created based on the pretense of a db directory, but must be based on
chain config read from the db. Using the DB presence causes Bor to get
instantiated for non bor chains which breaks.
* At the moment eth_calls on a remote daemon don't check Bor headers
prior to calling the EVM code as it was just using a fake ETHash
instance - which performs ETH header validation only.
The current version is mostly working but needs adapting to perform lazy
initialization of the engine.
This introduces _experimental_ block execution run by embedded Silkworm
API library:
- new command-line option `silkworm.path` to enable the feature by
specifying the path to the Silkworm library
- the Silkworm API shared library is dynamically loaded on-demand
- currently requires to build Silkworm library on the target machine
- available only on Linux at the moment: macOS has issue with [stack
size](https://github.com/golang/go/issues/28024) and Windows would
require [TDM-GCC-64](https://jmeubank.github.io/tdm-gcc/), both need
dedicated effort for an assessment
Whitelisting calculation of the roothash should not be dependent on the
bor api running. This will not always be the case, for example when
erigon is configured with a separate rpc deamon.
To fix this the calculation has been moved to Bor.
Additionally the redundant Bor API code has been removed as this is not
called by any code and the functionality looks to have migrated to the
turbo/jsonrpc package.
Fixes for label discrepancies in collector for summaries etc which have
a template which includes a quantile.
Initial native Prometheus client implementation of metrics - which is
currently turned off except for local testing and interface exports.
Closes#8078
This change is primarily intended to support go 1.21, but as a
side-effect requires updating libp2p, which in turn triggers an update
of golang.org/x/exp which creates quite a bit of (simple) churn in the
slice sorting.
This change introduces a new `cmp.Compare` function which can be used to
return an integer satisfying the compare interface for slice sorting.
In order to continue to support mplex for libp2p, the change references
github.com/libp2p/go-libp2p-mplex instead. Please see the PR at
https://github.com/libp2p/go-libp2p/pull/2498 for the official usptream
comment that indicates official support for mplex being moved to this
location.

This is a fix for at least one cause of this isssue:
https://github.com/ledgerwatch/erigon/issues/8212.
It happens after the end of the snapshot load, because the snapshot
processing which was introduced a couple of month ago does not deal with
validation of the headers at the start of the start of the chain.
I have also added a fix to the persistence so that the last snapshot is
recorded so that subsequent runs are not forced to process the whole
snapshot run from start.
The relationship between this an memory usage is that the fact that
headers are not processed leads to a queue of pending headers with size
of around 5GB. I have not changed any header parameters - so likely a
prolonged stop to header processing will result in a similar level of
memory growth.
Code to support react based UI for diagnostics:
* pprof, prometheus and diagnistics rationalized to use a single router
(i.e. they can all run in the same port)
* support_cmd updated to support node routing (was only first node)
* Multi content support in router tunnel (application/octet-stream &
appliaction/json)
* Routing requests changed from using http forms to rest + query params
* REST query requests can now be made against erigon base port and
diagnostics with the same url format/params

Some peer-review changes from the last related PR.
Addition of a flag for BlobSlots - for max allowed blobs per account in
txpool.
Use BlobFee from the block to validate txs in the pool.

This is the second part of the bor milestone release it contains the
following changes:
* Initialize services
* This is a change from the initial pull request I have moved all of the
initialization to the bor engine. To facilitate this I have just passed
in the heimdall client interface, rather than the whole engine
* Stage processing
* This is also a change from the original PR - the code is contained in
the bor heimdall stage rather than in headers - the effect should be the
same, but this needs testing

This is a non functional change which consolidates the various packages
under metrics into the top level package now that the dead code is
removed.
It is a precursor to the removal of Victoria metrics after which all
erigon metrics code will be contained in this single package.
Improve p2p error handling to propagate errors
from the origin up the call chain the Server peer removal code
using a new PeerError type containing a DiscReason and a more detailed
description.
The origin can be tracked down using PeerErrorCode (code) and DiscReason
(reason)
which looks like this in the log:
> [TRACE] [08-28|16:33:40.205] Removing p2p peer peercount=0
