* 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
* 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
* 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 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.
We no longer discriminate between ENR, MultiAddress or ENode
bootstrap records (all of them are remapped to ENodes).
The discovery loop will stochastically try to reconnect to
accidentally disconnected nodes.
* beacon node code cleanup
* rudimentary error checking on mainnet monitor
* start client even when sending deposit
* work around missing block number exception
* connect to testnet with web3 url
* pretty-print digests in json
* update to 0.10.1
* SSZ Generic and nbench uses the v0.10.1 fixtures
* Tests + spec links: v0.10.0 -> v0.10.1
* Add v0.10.1 TODO in get_latest_attesting_balance (forkchoice)
* SSZ Bytes are now ByteList
* Remove nim-result submodules that was leftover/added by mistake in the branch
* fix crash when state root is present but state is missing
* fix state root removal when state is removed
* fix block pool initialization which needs tail state
* remove tail block pruning
* incomplete - fork states are not pruned
* incomplete - fork blocks are not pruned
* incomplete - empty slot states are not pruned
* unknown - tail/finalized block on empty slot might be incorrect
* fix slot time navigation, add tests
* skip block proposal if head is more recent already - shouldn't happen
* use correct head when attesting to previous blocks
* log slot start/end processing
* state data cache in block pool
* keep head state around
* more attestation logic in attestation pool
* first fork choice tests (!)
* fix fork choice (it's still likely broken / out of date)
* re-enable test_interop based on zcli with 0.9.1 specs and update initialize_beacon_state_from_eth1(...) to 0.9.1
* switch many procs to funcs
* fix import os.nim instead; ospaths is deprecated [Deprecated] warnings
* off-by-one error in the returned range of blocks
* larger request time-outs to deal with non-responsive servers
* fix an unhandled exception when we fail to deliver a response chunk
