vc: fix missing attestations due to doppelganger in epoch 1 (#4688)
* log validator that triggers doppelganger
* move activity detection closer to where it's performed, record
aggregation as activity (since it's part of the liveness endpoint)
* vc: check for doppelgangers in epoch 0 also (so that activity in epoch
1 can happen)
* avoid some looping when processing activities

restore doppelganger check on connectivity loss (#4616)
* restore doppelganger check on connectivity loss

https://github.com/status-im/nimbus-eth2/pull/4398 introduced a
regression in functionality where doppelganger detection would not be
rerun during connectivity loss. This PR reintroduces this check and
makes some adjustments to the implementation to simplify the code flow
for both BN and VC.

* track when check was last performed for each validator (to deal with
late-added validators)
* track when we performed a doppel-detectable activity (attesting) so as
to avoid false positives
* remove nodeStart special case (this should be treated the same as
adding a validator dynamically just after startup)

* allow sync committee duties in doppelganger period

* don't trigger doppelganger when registering duties

* fix crash when expected index response is missing

* fix missing slashingSafe propagation

Types and scaffolding for EIP-4844 (#4365)
* Types and scaffolding for EIP-4844

This commit adds the EIP-4844 spec types, and fills in
scaffolding/boilerplate for the use of these types across the repo.

None of the actual EIP-4844 logic is introduced yet.

This follows the pattern used by @tersec when introducing Capella (#4276).

* use eth2-networks fork

* review feedback: add static check EIP4844_FORK_EPOCH == FAR_FUTURE_EPOCH

* review feedback: remove EIP4844 from /eth/v1/config/spec response

* Cleanup / review feedback

* Fix REST test

Fix a potential segfault and various potential stalls (#4003)
* Fixes a segfault during block production when the Keymanager API
  is disabled. The Keymanager is now disabled on half of the local
  testnet nodes to catch such problems in the future.

* Fixes multiple potential stalls from REST requests being done
  without a timeout. From practice, we know that such requests
  can hang forever if not cancelled with a timeout. At best,
  this would be a resource leak, at worst, it may lead to a
  full stall of the client and missed validator duties.

time: spring cleaning (#3262)
Time in the beacon chain is expressed relative to the genesis time -
this PR creates a `beacon_time` module that collects helpers and
utilities for dealing the time units - the new module does not deal with
actual wall time (that's remains in `beacon_clock`).

Collecting the time related stuff in one place makes it easier to find,
avoids some circular imports and allows more easily identifying the code
actually needs wall time to operate.

* move genesis-time-related functionality into `spec/beacon_time`
* avoid using `chronos.Duration` for time differences - it does not
support negative values (such as when something happens earlier than it
should)
* saturate conversions between `FAR_FUTURE_XXX`, so as to avoid
overflows
* fix delay reporting in validator client so it uses the expected
deadline of the slot, not "closest wall slot"
* simplify looping over the slots of an epoch
* `compute_start_slot_at_epoch` -> `start_slot`
* `compute_epoch_at_slot` -> `epoch`

A follow-up PR will (likely) introduce saturating arithmetic for the
time units - this is merely code moves, renames and fixing of small
bugs.

The spec imports are a mess to work with, so this branch cleans them up

* reexport crypto/digest/presets because these are part of the public
symbol set of the rest of the spec types

* fix circular deps in `ssz/spec_types` - this is the first step in
disentangling ssz from spec

the "natural" type set, then merge and so on, so no point in giving

remove false OnBlockAdded dependency on phase0 HashedBeaconState (#2661)
* remove false OnBlockAdded dependency on phase.HashedBeaconState

* introduce altair data types into block_clearance; update some alpha.6 spec refs to alpha.7; add get_active_validator_indices_len ForkedHashedBeaconState wrapper

* switch many modules from using datatypes (with phase0 states/blocks) to datatypes/base (fork-independent); update spec refs from alpha.6 to alpha.7 and remove rm'd G2_POINT_AT_INFINITY

* switch more modules from using datatypes (with phase0 states/blocks) to datatypes/base (fork-independent); update spec refs from alpha.6 to alpha.7

* remove unnecessary phase0-only wrapper of get_attesting_indices(); allow signatures_batch to process either fork; remove O(n^2) nested loop in process_inactivity_updates(); add altair support to getAttestationsforTestBlock()

* add Altair versions of asSigVerified(), asTrusted(), and makeBeaconBlock()

* fix spec URL to be Altair for Altair makeBeaconBlock()

Jacek Sieka abe0d7b4ae singe validator key cache
Instead of keeping a validator key list per EpochRef, this PR introduces
a single shared validator key list in ChainDAG, and cleans up some other
ChainDAG and key-related issues.

The PR does not introduce the validator key list in the state transition
- this is because we batch-check all signatures before entering the spec
code, thus the spec code never hits the cache.

A future refactor should _probably_ remove the threadvar altogether.

There's a few other small fixes in here that make the flow easier to
read:

* fix `var ChainDAGRef` -> `ChainDAGRef`
* fix `var QuarantineRef` -> `QuarantineRef`
* consistent `dag` variable name
* avoid using threadvar pubkey cache in most cases
* better error messages in batch signature checking

Perform attestation check before broadcast (#2550)
Currently, we have a bit of a convoluted flow where when sending
attestations, we start broadcasting them over gossip then pass them to
the attestation validation to include them in the local attestation pool
- it should be the other way around: we should be checking attestations
_before_ gossipping them - this serves as an additional safety net to
ensure that we don't publish junk - this becomes more important when
publishing attestations from the API.

Also, the REST API was performing its own validation meaning
attestations coming from REST would be validated twice - finally, the
JSON RPC wasn't pre-validating and would happily broadcast invalid
attestations.

* Unified attestation production pipeline with the same flow for gossip,
locally and API-produced attestations: all are now validated and entered
into the pool, then broadcast/republished
* Refactor subnet handling with specific SubnetId alias, streamlining
where subnets are computed, avoiding the need to pass around the number
of active validators
* Move some of the subnet handling code to eth2_network
* Use BitArray throughout for subnet handling

remove attestation/aggregate queue (#2519)
With the introduction of batching and lazy attestation aggregation, it
no longer makes sense to enqueue attestations between the signature
check and adding them to the attestation pool - this only takes up
valuable CPU without any real benefit.

* add successfully validated attestations to attestion pool directly
* avoid copying participant list around for single-vote attestations,
pass single validator index instead
* release decompressed gossip memory earlier, specially during async
message validation
* use cooked signatures in a few more places to avoid reloads and errors
* remove some Defect-raising versions of signature-loading
* release decompressed data memory before validating message
