* database state storage benchmarking via ncli_db
* more cleanups from immutable validator state branch
* unexport some eth2_network constants and remove unused variables/templates
* make two PeerScore constants public
* Create CLI tool for slashing export
* Use SQLite as a DB instead of a KV-store
* Keeps v1 and v2 DBs around
* Uses the same schema as Lighthouse v1.1.0
* Passes all interchange tests + skeleton of finalization pruning
* Removes tests that would violate v5 / minimal slashing DB and MinSlot rules
* Migration tool added using low-watermark scheme for faster migration of large number of validators
* force pushing to fix unstable base
* increase attestation/aggregate queue sizes
when there are many validators, many aggregates and attestations arrive
every slot - increase the queue size a bit - also do batches on each
idle loop iteration since it's fairly quick
* don't score subnets for now
* wrapping up
* refactor and cleanups
* gossip parameters fixes
* comment fix

* hotfix gossip scoring
* skip gossip scoring parameters validation as they violate for now (but does not matter cos we don't score)
* workaround again gossip validation
* expose node signatures
* format bitseqs as hex strings
* format trusted sigs as hex strings (same as untrusted)
* reuse rpc client sigs
* include validator index in duties
* move SyncInfo to spec
when there are many validators, many aggregates and attestations arrive
every slot - increase the queue size a bit - also do batches on each
idle loop iteration since it's fairly quick
* use IntSet rather than HashSet[ValidatorIndex]
* add bounds check before uint64 -> int conversion
* use intsets in block transitions
* remove superfluous Nim issue explanation/reference
* performance fixes
* don't mark tree cache as dirty on read-only List accesses
* store only blob in memory for keys and signatures, parse blob lazily
* compare public keys by blob instead of parsing / converting to raw
* compare Eth2Digest using non-constant-time comparison
* avoid some unnecessary validator copying
This branch will in particular speed up deposit processing which has
been slowing down block replay.

* use `idleAsync` to more evenly divide cpu attention when syncing in
particular - this gives networking better latency
* more strict exception handling in eth2_processor
* allow always-on subscription to all attestation subnets when gossiping
* in subscribe-all-subnets mode, consider all subnets to be stability subnets for ENR purposes
* remove await/async from sub/unsub
* fix unsubscribe wrong key (missed _snappy)
* use the right libp2p commit hash
* remove unused async
* fix inspector
* fix subnet calculation in RPC and insert broadcast attestations into node's pool
* unify codepaths to ensure only mostly-checked-to-be-valid attestations enter the pool, even from node's own broadcasts
* update attestation pool tests for new validateAttestation param

* fix subnet calculation in RPC and insert broadcast attestations into node's pool
* unify codepaths to ensure only mostly-checked-to-be-valid attestations enter the pool, even from node's own broadcasts
* update attestation pool tests for new validateAttestation param
* make subnet cycling more robust; use one stability subnet/validator; explicitly represent gossip enabled/disabled
* fix asymmetry in _snappy being used for subscriptions but not unsubscriptions
* remove redundant comment
* minimal RPC and VC support for infoming BN of subnets
* create and verify slot signatures in RPC interface and VC
* loosen old slot check
* because Slot + uint64 works but uint64 + Slot doesn't
* document assumptions for head state use; don't clear stability subnets; guard against VC not having checked an epoch ahead, fixing a crash; clarify unsigned comparison
* revert unsub fix
* checkpoint database at end of each slot
To avoid spending time on synchronizing with the file system while doing
processing, the manual checkpointing mode turns off fsync during
processing and instead checkpoints the database when the slot has ended.
From an sqlite perspecitve, in WAL mode this guaranees database
consistency but may lead to data loss which is fine - anything missing
from the beacon chain database can be recovered on the next startup.
* log sync status and delay in slot start message
* bump
* detect already-aggregate-voted condition before attestation pool; add is_aggregator tests
* replace pair of attestation-per-epoch tracking lists with single list and remove Option use
* fix attestation condition
* use safer type conversions; add more is_aggregator tests
* don't lag aggregated attestations by a slot
* don't use aggregation topic at all
* use aggregates again, but with aggressively low ATTESTATION_PROPAGATION_SLOT_RANGE; seems to hold on to LH 1.0 nodes
* clean up scaffolding and double ATTESTATION_PROPAGATION_SLOT_RANGE to 16
* increase ATTESTATION_PROPAGATION_SLOT_RANGE to 24
* increase ATTESTATION_PROPAGATION_SLOT_RANGE to 28 and isolate in only used function due to customization; remove TRAILING_DISTANCE machinery
