about 40% better slot processing times (with LTO enabled) - these don't
do BLS but are used
heavily during replay (state transition = slot + block transition)

* Slashing protection + interchange initial commit
* Restrict the when UseSlashingProtection dance in other modules
* Integrate slashing tests in other all_tests
* Add attestation slashing protection support
* Add a message that mention if built with/without slashing protection
* no op the initialization proc
* test slashing protection in Jenkins (temp)
* where to configure NIMFLAGS in Jenkins ...
* Jenkins -> ensure Built with slashing protection
* Add slashing protection complete import
* use Opt.get(otherwise)
* Don't use negation in proc name
* Turn slashing protection on by default
* Refactor peer_pool.
Fix eth2_network peer counters.
Fix PeerPool do not allow to add more peers when empty space available.
* Remove unused imports.
* Add test for a bug.
* Fix eth2_network disconnect should deletePeer not release.
More PeerPool refactoring.
* remove some superfluous gcsafes
* remove getTailState (unused)
* don't store old epochrefs in blocks
* document attestation pool a bit
* remove `pcs =` cruft from log
* Quick fix to prune some states, pending smarter state storage
Adverse effects might include slow rewinds - typically the protocol
doesn't ask for pre-finalized states but RPC might
* document issue, add test
* fix cache miss log
* stop discarding non-existent future epochs during epoch state transitions; remove a pointless StateCache() construction in advance_slots()
* update nbench to pass StateCache to process_slots()
This implements disparity, resolving a part of
https://github.com/status-im/nim-beacon-chain/issues/1367
* make BeaconTime a duration for fractional seconds
* factor out attestation/aggregate validation
* simplify recording of queued attestations
* simplify attestation signature check
* fix blocks_received metric
* add some trivial validation tests
* remove unresolved attestation table - attestations for unknown blocks
are dropped instead (cannot verify their signature)
* initial - cheaper pruning - addresses #1534
* Pass tests: update offset when pruning, proper handling of pruned parents
* Use options instead of nil for nilable newHead (finalization passing but rootcause not solved)
* First line of defense against stackoverflow in tests
* Fix compute_delta offset after pruning
* Rebase fix - medalla ready
* Remove Option[BlockRef]
Replace shuffling function with zrnt version - `get_shuffled_seq` in
particular puts more strain on the GC by allocating superfluous seq's
which turns out to have a significant impact on block processing (when
replaying blocks for example) - 4x improvement on non-epoch, 1.5x on
epoch blocks (replay is done without signature checking)

When blocks and attestations arrive, they are SSZ-decoded twice: once
for validation and once for processing. This branch enqueues the decoded
block directly for processing, avoiding the second, slow
deserialization.
* move processing of blocks and attestations to queue
* ...and out from beacon_node
* split attestation processing into attestations and aggregates
* also updates metrics
* clean up logging to better follow the lifetime of gossip: arrival,
validation and processing
* drop attestations and aggregates if there are too many
* try to prioritise blocks and aggregates before single-validator
attestations
* collect all epochrefs in specific blocks to make them easier to find
and to avoid lots of small seqs
* reuse validator key databases more aggressively by comparing keys
* make state cache available from within `withState`
* make epochRef available from within onBlockAdded callback
* integrate getEpochInfo into block resolution and epoch ref logic such
that epochrefs are created when blocks are added to pool or lazily when
needed by a getEpochRef
* fill state cache better from EpochRef, speeding up replay and
validation
* store epochRef in specific blocks to make them easier to find and
reuse
* fix database corruption when state is saved while replaying quarantine
* replay slots fully from block pool before processing state
* compare bls values more smartly
* store epoch state without block applied in database - it's recommended
to resync the node!
this branch will drastically speed up processing in times of long
non-finality, as well as cut memory usage by 10x during the recent
medalla madness.
* add attestation processing queue so attestations don't get processed
too early
* rework justified slot delay to match spec / lighthouse better
* keep less state in fork choice
* request epochref less
* Bump BLSCurve
* Use unified aggregation API
* use new blscurve with unified aggregate API
* bump
* fix toRaw
* replace state_sim combine with AggregateSignature
* Fix 32-bit
* Fix 32-bit for real and test deactivating ccache for fno-tree-lopp-vectorize flag
* change compilation switches to narrow down Linux issue
* Use -fno-tree-vectorize to disable both tree-loop-vectorize and tree-slp-vectorize
* blscurve now disables both Loop and SLP vectorization
* Add tests for the miracl/milagro fallback
* Travis has max log size of 4MB
* Test with Miracl in the finalization test
* fix state_sim log level
* Coment out the slow fallback tests
* fix invalid state root being written to database
When rewinding state data, the wrong block reference would be used when
saving the state root - this would cause state loading to fail by
loading a different state than expected, preventing blocks to be
applied.
* refactor state loading and saving to consistently use and set
StateData block
* avoid rollback when state is missing from database (as opposed to
being partially overwritten and therefore in need of rollback)
* don't store state roots for empty slots - previously, these were used
as a cache to avoid recalculating them in state transition, but this has
been superceded by hash tree root caching
* don't attempt loading states / state roots for non-epoch slots, these
are not saved to the database
* simplify rewinder and clean up funcitions after caches have been
reworked
* fix chaindag logscope
* add database reload metric
* re-enable clearance epoch tests
* names
* Eliminate possibilities for range errors and overflows
* Handle more properly invalid requests for furute slots
* Eliminate the confusing surrounding the MAX_REQUEST_BLOCKS constant
Addresses https://github.com/status-im/nim-beacon-chain/issues/1366
* Allow sync manager process blocks one by one.
* Log storeBlock() and updateHead() duration.
* Calculate duration only for blocks added without any error.
* Fix float compilation error.
* Fix duration.
* Fix SyncQueue tests.
