* remove incorrect/obsolete comment; deprecate BeaconState state transition functions
* remove deprecated state_transition(state: var BeaconState)
* add specific workarounds for state_transition() and process_slots() to nfuzz_block() and addTestBlock()
* Jenkins: add timeouts to testnet finalisation tests
- add nicer child process management to "launch_local_testnet.sh"
- correct a comment in "start.sh"
* the Jenkins worker's version of "timeout" doesn't support "-v"
* remove near-duplicate code paths: process_slot(), process_slots(), and state_transition() for BeaconState are now wrappers around the HashedBeaconState versions
* convert tests/test_state_transition.nim to use HashedBeaconState
* convert mocking infrastructure and spec_block/epoch_processing tests to use HashedBeaconBlock, and remove thus unused process_slot*(state: var BeaconState)
* ssz: move ref support outside
Instead of allocating ref's inside SSZ, move it to separate helper:
* makes `ref` allocations explicit
* less magic inside SSZ
* `ref` in nim generally means reference whereas SSZ was loading as
value - if a type indeed used references it would get copies instead of
references to a single value on roundtrip which is unexpected
TODO: EF tests would benefit from some refactoring since they all do the
same thing practically..

* refactor blook pool caches to directly use TableRef to avoid SSZ decoding, which was consuming 20% of profile on mainnet eth2_network_simulation
* use table's hasKeyOrPut
* bump eth2 spec reference to v0.11.1
* cache whole StateData objects and switch from expensive clear() to cheaper new object instantiation for caching
* remove scaffolding and stop re-assigning to part of StateData object
* 80-character lines
* Create a json log named "nbc.log" only when the --dev-build option
is specified to the connect_to_testnet script.
This option is specified for the targets "testnet0", "testnet1"
and "schlesi-dev"
Please see the newly added 'schlesi-dev' Makefile target.
It demonstrates how the log level can be specified for individual topics.
Additionally, when connecting to testnets like 'schlesi' there will be
two additional log files produced in the working directory:
* json-log.txt
* text-log.txt (in the textblocks format)
In BlockPool, we keep the head state around, so it's trivial to restore
the temporary state there and keep going as if nothing happened.
This solves 3 problems:
* stack space - the state copy on mainnet is huge
* GC scanning - using stack space for state slows down the GC
significantly
* reckless copying - the copy itself takes a long time
In state_sim, we'll do the same and allocate on heap - this helps a
little with GC - without it, the collection of the temporary strings
created with `toHex` while printing the json dominates the trace.
* add another check for inconsistent aggregation and committee length, since ncli_transition bypasses process_attestation(...)/check_attestation(...) and calls almost directly into process_epoch(...)
* bump validator functions to v0.11.1 spec references
* bump some spec references to v0.11.1
* poke
* Add "drop by score" ability to PeerPool.
Add tests.
Fix syncmanager queue to start from most fresh data.
* Fix endless cycle at the end of syncing process.
* reduce stack space usage in process_final_updates(...) to avoid fuzzed segfault in https://github.com/status-im/nim-beacon-chain/issues/921
* document motivation behind manually constructing hash_tree_root of a HistoricalBatch
* 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
