* 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
* crypto: cleanup
* fix several Defect-on-user-input
* make crypto interface more similar to secp
* use `crypto.nim` in all of nbc
* digest: raises
* fix
* vendor
* remove all but one UnusedImport warning
* bump a few more spec version references from v0.10.1 to v0.11.1
* more v0.10.1 spec reference updates/removals
* yet more v0.10.1 spec reference updates
* 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* fix fork choice (it's still likely broken / out of date)
* rename get_genesis_beacon_state(...) to initialize_beacon_state_from_eth1(...); remove unused vestiges get_temporary_block_header(...) and get_empty_block(...); partly align initialize_beacon_state_from_eth1(...) with 0.8.0 version; implement CompactCommittee object type; update process_final_updates(...) to 0.8.0
* mark get_shard_delta(...) as 0.8.0
* mark get_total_active_balance(...) and epoch transition helper functions as 0.8.0
* move FORK_CHOICE_BALANCE_INCREMENT, not in spec anymore, to sole user in fork_choice
* Initial move constants to mainnet preset
* Bump fixtures to include shuffling with minimal preset
* Add minimal preset with shuffling test
* Add minimal preset to the full test suite
* use preset() everywhere
* signed_root -> signing_root
* implement new process_deposit; update timing parameters to 0.6.1; update Deposit to 0.6.1 and remove DepositInput
* update get_active_validator_indices and get_epoch_committee_count to 0.6.1; rm get_current_epoch_committee_count, get_previous_epoch_committee_count, and get_next_epoch_committee_count; bump state_sim default validator count a bit more
* re-introduce 0.5.1-ish get_active_validator_indices, get_epoch_committee_count as scaffolding for still-0.5.1ish shuffling
* avoid crash on invalid block production (fixes#209)
* fetch blocks every second, roughly
* fix start.sh param order
* run beacon node sim at slower pace
* no need to pass prev_block_root when updating state
* some Slot fixes
* fix `hash_tree_root` for Slot, Epoch
* detect missing hash_tree_root type support
* remove some <0.5 state checks
* ssz: update to 0.5.1:ish
* slightly fewer seq allocations
* still a lot of potential for optimization
* fixes#174
* ssz: avoid reallocating leaves (logN merkle impl)
* fix state db lookup typo
* fix randao reveal slot when proposing blocks
* only store blocks that can be applied to a state
* store state at every epoch boundary (yes, needs pruning!)
* split out state advancement function when there's no block
* default state sim to 0.9 attestation ratio
* implement in-memory block graph
* store tail block in database
* resolve unknown parents by syncing them from peers
* introduce concept of resolved blocks and attestations - those that
follow minimal protocol rules
* update state head lazily
* log more stuff
* shortHash -> shortLog
* start 9/10 beacon nodes by default, last can be started manually
* see also #134
* fix start.sh epoch length
