By pre-seeding the sync committee cache when applying blocks, we avoid a
significantly expensive validator set traversal / sync committee index
construction during sync / block application - 20-30% sync speedup
post-altair.
* also cache/reload total active balance for another cool 10%
The `/etc/os-release` file exists in most distributions and can be
easily read in Bash by sourcing it:
```
> docker run --rm -it debian:bullseye
root@2f5d6e038738:/# grep '^ID=' /etc/os-release
ID=debian
```
```
> docker run --rm -it ubuntu:22.04
root@316b572b6e4d:/# grep '^ID=' /etc/os-release
ID=ubuntu
```
The dependency on `lsb-release` tool
is unnecessary, and pulls in additional big dependencies like `python3`:
```
# apt show lsb-release | grep Depends
Depends: python3:any, distro-info-data
```
Which if used in a Docker container would make it unnecessarily big.

While syncing the finalized portion of the chain, the execution client
cannot efficiently sync and most of the time returns `SYNCING` - in this
PR, we use CL-verified optmistic sync as long as the block is claimed to
be finalized, only occasionally updating the EL with progress.
Although a peer might lie about what is finalized and what isn't,
eventually we'll call the execution client - thus, all a dishonest
client can do is delay execution verification slightly. Gossip blocks in
particular are never assumed to be finalized.
Extends fork choice state to also track slot numbers to improve accuracy
of `/eth/v1/debug/fork_choice` endpoint. Autoenable this API on devnet,
and disable some extra checks on devnet to aid focused testing efforts.
Align fork choice pruning logic with API based on checkpoints vs root.
* clean up some Nim 1.2 workarounds
* re-add notes about JS backend
* another proc/noSideEffect -> func
* revert ncli/ncli_common.nim changes; 19969 evidently wasn't backported to 1.6
To allow LC data retention longer than the one for historic states,
introduce persistent DB caches for `current_sync_committee` and
`LightClientHeader` for finalized epoch boundary blocks.
This way, historic `LightClientBootstrap` requests may still be honored
even after pruning. Note that historic `LightClientUpdate` requests are
already answered using fully persisted objects, so don't need changes.
Sync committees and headers are cached on finalization of new data.
For existing data, info is lazily cached on first access.

The "on" default for validator monitor details incurs a heavy
performance penalty on large-validator setups - this may cause excess
memory usage or slowdowns when metrics are queried - this PR changes the
default to off, as was intended for the 23.1.0 release.
* debug log upon sidecar validation failure
* Fill in signature catch upon SignedBeaconBlockAndBlobsSidecar deser
* Always fill blobssidecar slot and root
* Skip lastFCU when eth1monitor is nil
* fix
* Use cached root
When the epoch boundary block is missed, we incorrectly assume that the
next couple blocks improve finality, leading to repeated pushes of the
same light client finality update and incorrectly ignoring some gossip.
* combine common implementation of LC helpers
Combine replicated helper code from Altair/Capella/EIP4844 into single
`Forky` based implementation. Also convert `template` to `func` to avoid
selection of incorrect overload.
* fix
* eip4844 beacon block proposals
* Don't fetch blobs under minimal preset
@tersec's summary of the issue:
BlobsBundleV1 in the execution API spec assumes a mainnet preset blob
size, where the EIP4844 consensus spec defines
FIELD_ELEMENTS_PER_BLOB: 4 under the minimal preset, which leads to a
Blob having a length of 4 * 32, not 4096 * 32 which BlobsBundleV1
requires.
* Revert unintentional script change
