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.

Add code to the headers state to break processing if a bor milestone
rewind is detected.
The rewind processing happens in the bor/heimdall stage - this change
just avoids unnecessary header loading
if a milestone fork is likely to be detected

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

For example, erigon on devnet8 marked a block as bad due to
"mdbx_cursor_open: cannot allocate memory":

With this PR blocks are marked as bad only on genuine protocol errors.
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.
ergon/metrics contains a lot of unused types - the pull is removing them
prior to rationalizing between Prometheus and Victoria Metrics types.
It also have upgrades of golang-lru + sets types to v2 when possible.
This is an update of:
https://github.com/ledgerwatch/erigon/pull/7846
which uses a local fork of victoria metrics to include the changes that
https://github.com/anshalshukla added to the original for we where
using.
It also includes code to address the duplicate metrics issue identified
here:
https://github.com/ledgerwatch/erigon/issues/8053
It has one more associated fix which is to correctly add a metadata
label to counters, these where previously labelled as gauges.
e.g.
```
# TYPE p2p_peers counter
p2p_peers 0
```
rather than
```
# TYPE p2p_peers gauge
p2p_peers 0
```

I have added:
```go
{
ID: stages.BorHeimdall,
Description: "Download Bor-specific data from Heimdall",
Forward: func(firstCycle bool, badBlockUnwind bool, s *StageState, u Unwinder, tx kv.RwTx, logger log.Logger) error {
if badBlockUnwind {
return nil
}
return BorHeimdallForward(s, u, ctx, tx, borHeimdallCfg, true, logger)
},
Unwind: func(firstCycle bool, u *UnwindState, s *StageState, tx kv.RwTx, logger log.Logger) error {
return BorHeimdallUnwind(u, ctx, s, tx, borHeimdallCfg)
},
Prune: func(firstCycle bool, p *PruneState, tx kv.RwTx, logger log.Logger) error {
return BorHeimdallPrune(p, ctx, tx, borHeimdallCfg)
},
},
```
To MiningStages as well as Default as otherwise bor events are not added
when the block producer creates new blocks.
There are a couple of questions I have around this implementation:
* Is this the right place to add this
* As the state is also executed when the default stage is processed ther
is some duplicate processing for the block producing node.
* There is a duplicated call to heimdall which could be removed if the
stages share state - but its not clear if we want to do this.
* I don't think the mining stage needs to prune as this will be
replicated in the default iteration
This can be tested using the devnet with the following arguments:
```
--chain bor-devnet --bor.localheimdall --scenarios state-sync
```
This will generate sync events via an ethereum devnet which are
transmitted to bor chain and will be executed at the end of the snapshot
delay, which results in events generated from the bor chain. This tests
the whole sync, block generation, event lifecycle. As it needs to wait
for sprints to end after a sufficient delay it is quite slow to run.
This fixes an indexing panic when bor sync event logs are returned via a
subscription.
It applies the same tx computation that is used by the getlogs rpc call
This request implements the insertion of Bor ephemeral transactions into
snapshot indexes.
I does this by taking the block hash from the header index and passing
it to the transaction indexer to add an additional index entry per block
into the transaction hash -> block index.
The passed entries are currently contained in an in memory array which
is (32 * number of blocks / sprint size) bytes.
In addition to the functional code there is also an update to the
`dump_test.go` so that it runs `DumpBlocks` to exercise the indexing
code. To facilitate this the `InsertChain` method in `mock_sentry` has
been modified so that it can process >128 blocks.
The code in this request also includes additional bor/consensus code
with the following functions:
`CalculateSprint`
`CalculateSprintCount`
The first function is a modification of the code in erigon-lib so that
the sprints are numerically rather than lexically ordered. This code
should be migrated to erigon-lib and should have its sprint set
calculated once from its underlying map rather than this process being
repeated every calculation.

This PR separates ENGINE from Ethbackend. It makes it so:
1) EthBackend not a god class
2) We can abstract away engine API so that we can make it CL-like and
enable Consensus-Execution driven design
3) Objective is Json-RPC -> Engine Consensus Module -> Execution module.
- breaks dependency from staged_sync to package with block_reader
implementation
- breaks dependency from snap_sync to package with block_reader
implementation
- breaks dependency from mining to txpool implementation
