* add another check for inconsistent aggregation and committee length, since ncli_transition bypasses process_attestation(...)/check_attestation(...) and calls almost directly into process_epoch(...)

* fix remaining block pool extended validation issues and re-enable first-block-received and block-signature EV checks; enable Merkle validation in beacon_node in eth2_network_simulation; refactor some Merkle proof generation code outside tests/ as a result
* re-enable Merkle validation skipping, since while it works on make eth2_network_simulation, it has issues with local testnet
* tighten already-seen-block blockpool check; move comment closer to conceptually proximate code; queue up maybe-future-valid-blocks as pending to keep libp2p-synchronous interrupt handling time lower
* revert the cleanups, now in a separate PR
* remove the remaining merkle_minimal cleanup remnants, also moved to other PR
* restore PR to only modifying one file after rebasing
* use signatures as summary to compare block contents
* switch signature comparison to be raw byte-wise to ensure no attempts to deserialize it to valid (or not) BLS signatures first
* fix mainnet finalization and swith eth2_network_simulation to a kind of small-mainnet profile
* Fix slot reference in trace logging
* bump a couple of spec refs from v0.11.0 to v0.11.1
* bump another spec ref to v0.11.1, one more try at Jenkins test vector download CI issue
* fix other slot reference in trace logging and skip past single-block/multi-slot gaps to re-approach from ancestry side by state_transitioning, by requiring exact match on both root hash and slot for fast path
* make more precise the fast path condition
* redo logic to make uniform with BeaconChainDB; fix chronos deprecation warning
* revert not-working replacement of deprecated chronos futures `or`
* switch testnet1 to mainnet
* if we don't have validators, don't consider aggregation work
* if we do have validators, don't aggregate when we're out of sync
* when we do aggregate, use a fresh state, and not one from before
sleeping
* fix warnings by switching from deprecated chronos API addTimer(...) to setTimer(...) and removing especially some unnecessary chronicles and extras imports from test suite modules
* update a couple v0.10.1 spec references to v0.11.1
* crypto: cleanup
* fix several Defect-on-user-input

* digest: raises
* fix
* vendor
* remove all but one UnusedImport warning
* bump a few more spec version references from v0.10.1 to v0.11.1
* more v0.10.1 spec reference updates/removals
* yet more v0.10.1 spec reference updates
* refactor and fix merkle proof construction in test suite and thereby remove most remaining skipMerkleValidation flags, now unnecessary
* a few non-semantic comment update/removals
* initial fork-choice refactor
* Add fork_choice test for "no votes"
* Initial test with voting: fix handling of unknown validators and parent blocks
* Fix tiebreak of votes
* Cleanup debugging traces
* Complexify the vote test
* fakeHash use the bigEndian repr of number + fix tiebreak for good
* Stash changes: found critical bug in nimcrypto `==` and var openarray
* Passing fork choice tests with varying votes
* Add FFG fork choice scenario + fork choice to the test suite
* Not sure why lmdb / rocksdb reappeared in rebase
* Add sanity checks to .nimble file + integrate fork choice tests to the test DB and test timing
* Cleanup debugging echos
* nimcrypto fix https://github.com/status-im/nim-beacon-chain/pull/864 as been merged, remove TODO comment
* Turn fork choice exception-free
* Cleanup "result" to ensure early return is properly used
* Add a comment on private/public error code vs Result
* result -> results following https://github.com/status-im/nim-beacon-chain/pull/866
* Address comments:
- raises: [Defect] doesn't work -> TODO
- process_attestation cannot fail
- try/except as expression pending Nim v1.2.0
- cleanup TODOs
* re-enable all sanity checks
* tag no raise for process_attestation
* use raises defect everywhere in fork choice and fix process_attestation test
* initial attestation aggregation
* fix usage of committee index, vs index in committee; uniformly set trailing/following distance; document how the only-broadcast-if mechanism works better and what aggregation already happens, not otherwise sufficiently clear; use correct BlockSlot across epoch boundaries
* address inconsistent notion of which slot in past to target for aggregate broadcast; follow 0.11.x aggregate broadcast p2p interface topic
* Fix get_slot_signature(...) call after get_domain(...) change required genesis_validators_root
* mark all spec references which aren't dealt with in other PRs as v0.11.1
* update two more spec refs to v0.11.1
* initial extended validation setup
* flesh out all TODO items for attestation and beaconblock verification
* fix finalization and add chronicles debugging messages
* directly use blockPool.headState rather than pointlessly updating it and document this constraint
* fix logic relating to first-attestation checking; support validating blocks across multiple forks
* initial 0.11.1 spec commit; no test regressions and finalizes in eth2_network_simulation
* with BLS 0.10/0.11 available, stop skipping attester slashing, proposer slashing, and voluntary exist operations fixture tests
* switch param orders to group state.{fork, genesis_validators_root}; bump spec/datatypes spec version for network purposes
* mark attestation construction and broadcast and some minimal/mainnet constants as 0.11.1-compatible; remove phase 1 sharding constants from minimal which don't exist in that preset
* complete (except for get_domain(...)) 0.11.0 beacon chain spec update
* mark compute_start_slot_at_epoch(...), is_active_validator(...), compute_signing_root(...), and get_seed(...) as 0.11.0
* Initial implementation of runtime bls skipping.
Add libnfuzz skipBLSValidation handling, check that it propagates.
* Rename skipBLSValidation -> skipBlsValidation, start skipStateRootValidation
* Replace skipValidation flags with more granular flags.
Also added skipBlockParentRootValidation flag
Mainly replaced with skipBlsValidation but also StateRoot or
BlockParentRootValidation flags where appropriate.
* Adjust interop test to pass when skipping merkle validation.
* Stop skipping validation for mainchain_monitor.
* Remove comment.
* Also skipMerkleValidation for test_beacon_chain_db.
This used to behave properly before the rebase, but currently
it forces the bootstrap node to exit, because it ends up being
launched with an ENR list telling it to connect to itself.
The root cause will be investigated in a follow-up PR.
Turns out the DiscV5 code relies heavily on the presence of ENR
records at the moment, so we cannot drive it with ENodes. @kdeme
is working on refactoring that will relax these requirements.
* The bootstrap_nodes.txt file in the node's data dir is now optional
* Log more data on start-up
* Use the latest ENR APIs
* Fix simulation build errors
