* 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()
* bump chronos
this reverts backwards-incompatible changes to CancelledError and
resores other functionality.
chronos metrics are lost and will need to be reimplemented.
* bump
* ignore sqlite WAL journal files in git; switch attestation resolved from info to debug
* promote sent attestations/blocks to notice rather than demote resolved attestations/blocks to debug
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)
* Jenkins: run benchmarks
* don't exit the workspace
* try calling the benchmark plugin from the config file
* pass all params
* separate Jenkins job for benchmarks
* harden beacon_pending_deposits metrics calculation
* ...
* move beacon_pending_deposits and beacon_processed_deposits_total out of specs and into chain DAG
* 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]
* book updates
* save progress
* save progress
* work on deposit data section + edits
* title edit
* minor edits
* edits and clarifications
* add images, launchpad steps, and a note on expected wait time
* add images + edits
* restructure, simplify, edits
* faq corrections
* rework intro: cp
* update intro and faq
* add note on requestiong goerli eth
* typo fix
* add numbers to steps in walletstore guide"
* chapter 8 title: replace Nimbus with NBC

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)
