Batch slashing protection registration (#5604)
This PR brings down the time to send 100 attestations from ~1s to
~100ms, making it feasible to run 10k validators on a single node (which
regularly send 300 attestations / slot).

This is done by batching the slashing protection database write in a
single transaction thus avoiding a slow fsync for every signature -
effects will be more pronounced on slow drives.

The benefit applies both to beacon and client validators.

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

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.

Harden CommitteeIndex, SubnetId, SyncSubcommitteeIndex (#3259)
* Harden CommitteeIndex, SubnetId, SyncSubcommitteeIndex

Harden the use of `CommitteeIndex` et al to prevent future issues by
using a distinct type, then validating before use in several cases -
datatypes in spec are kept simple though so that invalid data still can
be read.

* fix invalid epoch used in REST
`/eth/v1/beacon/states/{state_id}/committees` committee length (could
return invalid data)
* normalize some variable names
* normalize committee index loops
* fix `RestAttesterDuty` to use `uint64` for `validator_committee_index`
* validate `CommitteeIndex` on ingress in REST API
* update rest rules with stricter parsing
* better REST serializers
* save lots of memory by not using `zip` ...at least a few bytes!
