Changes:
* Do not send separate network packets for response codes and msg
len prefixes
* Close streams according to the spec
* Implement more timeouts according to the spec
* Make hello requests during syncing to update our knowledge of
the head block of the other peer.
* Hello is no longer a handshake message
(all handshakes related code was deleted for clarity)
* Deal with the single-parameter inlining defined in the new spec
* add test suite for voluntary exit
* update API to process_voluntary_exit
* Add range check of validator_index for voluntary exits
* Revert to dual single + multiple voluntary exits API + enable in test suite
* no cache or mocking needed
* Add attestation unit test
* process_attestation doesn't throw exceptions
* Allow SSZ deserialization of both real and invalid signatures
* Add new process_attestation checks - pass all process_attestation tests
* Add sanity check for #361
* Fix SSZ testing after fromBytes/fromSSZBytes changes
* Fixed getBeaconBlocks() and getRecentBeaconBlocks() to use BlockPool, not db.
* Got the sync_protocol to compiling state; Removed all obsolete RPC calls
* fix network sim
* mark BeaconState, state list/vector lengths, misc values, get_base_reward(...), verifyStateRoot(...), and process_slot(...) as 0.8.3; update minimal/mainnet config initial values to 0.8.3 by removing GENESIS_FORK_VERSION
* Add sanity check for slot processing (also impacted by https://github.com/status-im/nim-beacon-chain/issues/373)
* use reportDiff also for all state tests vs EF
* initial sanity checks for blocks - workaround zero signature in block headers: https://github.com/status-im/nim-beacon-chain/issues/374
* Remove generic object variant compare commented code
* Add the one block state transition sanity checks
* generalize blocks test to multiple blocks
* simplify slots test runner
* Add official epoch transitions, sanity blocks, sanity slots to the test suite
* Fix index out-of-bounds in initiate_validator_exit - enable proposer slashings unittest
* Update BLS fixtures to 0.8.3
* Bump fixtures with shuffling with minimal preset
* Update shuffling tests
* parseTest generic over file format (Json or SSZ)
* Initial crosslink parsing commit for debugging Nim crash
* Workaround https://github.com/status-im/nim-beacon-chain/issues/369
* Crosslink test works for minimal - https://github.com/status-im/nim-beacon-chain/issues/369 is back on mainnet
* Use ref objects to workaround https://github.com/status-im/nim-beacon-chain/issues/369
* Generalize state transition epoch test to all epoch tests
* Fix slashing (potential uint64 overflow in previous spec)
* Add a state debugging macro to deeply inspect the wrong fields
* make reportDiff visible
* Improve the debug state macro for containers
* add interop launcher scripts
* stick validator_keygen into beacon_node
* fix lmd ghost slot number on missing block
* use mocked eth1data when producing blocks
* use bls public key method for withdrawal credentials
* fix deposit domain
* prefer lowercase for a bunch of toHex
* build simulation binary in data folder to avoid data types confusion
* Introduce new mocking proc to replace:
- makeFakeValidatorPrivKey
- hackPrivKey
- getNextBeaconProposerIndex
- addBlock
- makeBlock
* Add comments on datastructure unsynced with the spec
* Add merkle tree constructor and initial mocking for deposits (missing merkle proofs)
* [Mock] Implement sparse merkle tree and merkle proof builder
* [Mocking] Genesis deposits
* Add compact_committees_roots init + mock genesis state
* [Tests] Add first deposit test using the new mocking procedures
* [Tests -deposits] add at and over 32 ETH deposit tests
* [Tests - deposits] Add test for validator top-up
* [Tests -deposits] Mention the TODO to test for invalid conditions
* [Tests] Add stub to test "is_valid_genesis_state"
* [Merkle proofs] Implement round-trip checks
* Deactivate roundtrips test
* SSZ - use EF convention for hash_tree_root / hashTreeRoot
* [Tests - Attestation] Attestation mocking + initial test
* Add mocking + 3 new tests for valid attestations + mention future invalid attestation tests
* Add crosslinks test (1 failing to attestations in block being duplicated in state transition)
* Single attestation crosslink test - workaround https://github.com/status-im/nim-beacon-chain/issues/361
* Add test for failed crosslink penalty
* Rebase fixes + add refactored tests to test suite
* justif-finalization helpers first batch
* Add 234 finalization tests
* Fix justif test, Rule I 234 finalization does not happen with sufficient support.
(Also unittest check template does not fail properly in some cases)
* Add tests for all finalization rules
* Properly delete nim-byteutils following c91727e7e5 (diff-7c3613dba5171cb6027c67835dd3b9d4)
* use digest helper for deposit root
* relax attestation validation when attestation is incoming but make it
more strict when adding to block
* share attestation validation logic between attestation pool and state
transition
* remove a bunch of redundant logging
* fix potential underflow in attestation delay checking
* fix committee used for attestation shard selection when attesting
* fix attestation data construction
