reduce `nim-eth` dependencies just for RNG (#5099)
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.

use correct slot when producing sync aggregate around forks (#5089)
`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.

segregate sync committee messages by period / fork (#4953)
`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.

drop subset sync contributions in gossip (#4490)
* correctly report ignored contributions in metrics
* avoid counting subset contributions in vmon (bring in line with
attestation aggregates)
* avoid signature checks for subset attestations

A being a non-strict subset is a sufficient condition to ignore.

enable `styleCheck:usages` (#3573)
Some upstream repos still need fixes, but this gets us close enough that
style hints can be enabled by default.

In general, "canonical" spellings are preferred even if they violate
nep-1 - this applies in particular to spec-related stuff like
`genesis_validators_root` which appears throughout the codebase.

dynamic sync committee subscriptions (#3308)
* dynamic sync committee subscriptions

* fast-path trivial case rather than rely on RNG with probability 1 outcome

Co-authored-by: zah <zahary@gmail.com>

* use func instead of template; avoid calling async function unnecessarily

* avoid unnecessary sync committee topic computation; use correct epoch lookahead; enforce exception/effect tracking

* don't over-optimistically update ENR syncnets; non-looping version of nearSyncCommitteePeriod

* allow separately setting --allow-all-{sub,att,sync}nets

* remove unnecessary async

batch-verify sync messages for a small perf boost (#3151)
* batch-verify sync messages for a small perf boost

Generally reuses the same structure as attestation and aggregate
verification

* normalize `signatures` and `signature_batch` to use the same pattern
of verification
* normalize parameter names, order etc for signature stuff in general
* avoid calling `blsSign` directly - instead, go through `signatures`
consistently

Cleanups (#3123)
Renames and cleanups split out from the validator monitoring branch, so
as to reduce conflict area vs other PR:s

* add constants for expected message timing
* name validators after the messages they validate, mostly, to make
grepping easier
* unify field naming of EpochInfo across forks to make cross-fork code
easier

remove privkey from mock withdrawal credentials (#2936)
In tests, the private key was put into the validator deposit's withdraw
credentials so that it can be recovered later. This leads to problems
when creating the validators through other means that do not put the key
there. In general, mock private keys only depend on the validator index,
though, and because it is clear what the index of a validator is, it is
not actually needed to put the key into the credentials.
