Split up the `ShufflingRef` acceleration logic into generically usable
parts and attester shuffling specific parts. The generic parts could be
used to accelerate other purposes, e.g., REST `/states/xxx/randao` API.
To enable additional use cases, e.g., `/states/###/randao` beacon API,
`ShufflingRef` acceleration logic needs to be able to operate on parts
of the DAG that do not have `BlockRef`. Changing `commonAncestor` to
act on `BlockId` instead of `BlockRef` is a step toward that and also
simplifies the logic some more.
Post-merge blocks contain all information to directly obtain RANDAO
without having to load any additional info. Take advantage of that to
further accelerate `ShufflingRef` computation. Note that it is still
necessary to verify that `blck` / `state` share a sufficiently recent
ancestor for the purpose of computing attester shufflings.

Running `makeTestDB` in tests currently always initializes DB with a
`phase0` state, preventing tests that configure a fork schedule that
starts in a different fork from working properly. Fix that by upgrading
the genesis state to whatever fork the fork schedule starts with.
Current RANDAO recovery logic is quite complex as it optimizes for the
minimum amount of database reads. Loading blocks isn't the bottleneck
though, so rather make the implementation more concise by avoiding the
complex strategy planning step. Note that this also prepares for an even
faster implementation for post-merge blocks in the future that extracts
RANDAO from `ExecutionPayload` directly if available, so even in cases
where efficiency is slightly lower, only historical data is affected.

When the requestmanager is busy fetching blocks, the queue might get
filled with multiple entries of the same root - since there is no
deduplication, requests containing the same root multiple times will be
sent out.
Also, because the items sit in the queue for a long time potentially,
the request might be stale by the time that the manager is ready with
the previous request.
This PR removes the queue and directly fetches the blocks to download
from the quarantine which solves both problems (the quarantine already
de-duplicates and is clean of stale information).
Removing the queue for blobs is left for a future PR.

* early exit `commonAncestor` when comparing with `finalizedHead`
As all `BlockRef` lead to `finalizedHead` (`parent == nil`),
can shortcut in that situation and immediately return `finalizedHead`
if passed as one of the arguments.

We have several modules that import `nim-eth` for the sole purpose of
its `keys.newRng` function. This function is meanwhile a simple wrapper
around `nim-bearssl`'s `HmacDrbgContext.new()`, so the import doesn't
really serve a use anymore. Replace `keys.newRng` with the direct call
to reduce `nim-eth` imports.
* require sync committee supermajority in CI
To better catch problems with sync committee messages in CI, extend
local testnet simulation to also verify that each block is signed
by a supermajority of the sync committee.
Requires #5083 and #5084
* lint
`produceSyncAggregate` is called in new slot when block is produced,
while the other functions in `sync_committee_msg_pool` are called in
previous slot. So, need to subtract 1 slot when producing sync aggregate
to accept the signatures using the old digest during fork transition.
* Refactor api.nim to provide more informative failure reasons.
Distinct between unexpected data and unexpected code.
Deprecate Option[T] usage.
* Fix 400 for produceBlindedBlock().
Get proper string conversion for strategy.
* Fix SSZ encoded versions of ProduceBlockResponseV2, ProduceBlockResponseV2 can be received and decoded.
Fix done() warnings.
Bump presto.
* Fix compilation error with new presto.
Use TcpNoDelay option for Web3Signer.
* Fix produceBlockV2() should provide SSZ responses too.
* Address block encoding issue.
* Fix signing test.
* Bump presto.
* Address review comments.
* also pack attestations where LMD vote is orphaned
When `attestation.data.beacon_block_root` gets orphaned, attestations
with a good `attestation.data.target.root` may still be valuable.
The LMD GHOST vote is not relevant for attestation rewards.
Switch to use the FFG vote (`attestation.data.target.root`) instead,
gossip validation ensures it is an ancestor of `beacon_block_root`.
* lint
* Clarify addOrphan error/logging
addOrphan returned a bool to indicate success. Change this to a Result
so that different errors can be distinguished.

When doing sync for blocks older than
MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS, we skip the blobs by range
request, but we then pass en empty blob sequence to
validation, which then fails.
To fix this: Use an Option[Blobsidecars] to allow expressing the
distinction between "empty blob sequence" and "blobs unavailable". Use
the latter for "old" blocks, and don't attempt to run blob validation.
`SyncCommitteeMsgPool` grouped messages by their `beacon_block_root`.
This is problematic around sync committee period boundaries and forks.
Around sync committee period boundaries, members from both the current
and next sync committee may sign the same `beacon_block_root`; mixing
the signatures from both committees together is a mistake. Likewise,
around fork transitions, the `signing_root` changes, so those messages
also need to be segregated.
