Speed up process_crosslinks(...) and get_crosslink_deltas(...) by 10x - 15x in state_sim (#314)
* remove some low-hanging perf silliness from get_winning_crosslink_and_attesting_indices(...) and switch inner/outer loop nesting order to get 10-15x function speedup for 128 and 512 validator cases by avoiding accidentally quadratic behavior, while keeping function signature unchanged and allowing easy ongoing verification of correctness of optimization

* avoid memory allocation with an openarray rather than seq

* update get_crosslink_deltas(...) to 0.8.0

* move non-spec ValidatorSetDeltaFlags from datatypes.nim to sync_protocol; fix mainnet MIN_ATTESTATION_INCLUSION_DELAY preset; update get_attestation_deltas(...) to 0.8.0; for 512 validators, get 90x speedup for get_attestation_deltas(...) from 179s to 2s

* explain purpose of when false portions, so they can be removed once accomplished

Dustin Brody e4321dc4ed Initial frozen phase 0/v0.8.0 spec (#305)
* rename slot_to_epoch(...) to compute_epoch_of_slot(...)

* rename aggregation_bitfield/custody_bitfield fields to aggregation_bits/custody_bits; rename convert_to_indexed(...) to get_indexed_attestation(...); mark BeaconBlockHeader as 0.8.0; update minimal preset MIN_ATTESTATION_INCLUSION_DELAY/time parameters in general to 0.8

* fix beacon node compilation; it used slightly different capitalizations of slot_to_epoch/slotToEpoch

* mark integer_squareroot(...), Deposit, VoluntaryExit, and Transfer as 0.8.0; rename get_epoch_start_slot(...) to compute_start_slot_of_epoch(...)

* add new Domain alias for uint64; rename bls_domain(...) to compute_domain(...), MAX_INDICES_PER_ATTESTATION to MAX_VALIDATORS_PER_COMMITTEE, and SignatureDomain to DomainType; update get_domain(...) to 0.8.0

* update/mark initiate_validator_exit(...) and Crosslink as 0.8.0; rename BeaconState.latest_block_roots -> BeaconState.block_roots; mark HistoricalBatch as 0.8.0

Dustin Brody f36c2d86dc begin 0.5.0 spec update (#179)
* begin 0.5.0 spec update: parent_root -> previous_block_root, BeaconState.justified_epoch -> BeaconState.current_justified_epoch, DOMAIN_PROPOSAL -> DOMAIN_BEACON_BLOCK, temporarily rename BeaconBlockHeader to BeaconBlockHeaderRLP to allow for gradual re-merging without disrupting RLP; mark a few unchanged functions and data types, implement get_temporary_block_header/get_empty_block/should_update_validator_registry/processBlockHeader/cacheState; update a few others

* a dozen or so more trivial mostly comment changes, finding more unchanged parts of 0.5.0

* several more trivial changes; goal is to reduce noise around the upcoming substantial changes (epoch processing, etc)

Zahary Karadjov 903cb8a8b5 A LibP2P-based networking stack;
To enable it, comment out the 'withLibp2p' line in nim.cfg

The history was squashed in order to remove an accidentally
commited binary file.

Other changes:

* SSZ was adapted to use the common serialization framework

* gossibsup.subscribe is not using async handlers at the moment
  and this allowed me to simplify it

spec updates (#34)
* spec updates

* make several constants uint64 to help minimize casting
* document data type woes - will have to revisit these
* change comment style on fields and constants to make room for better
comments
* add BLSVerify and BLSAddPbkeys facades to insulate spec code from
milagro
* fix proof of possession type
* drop explicitly ordered container fields from ssz - there's an issue
open to sort this out before committing it to the spec
