Zahary Karadjov 8da71715eb Bump the beacon_node version; Make the simulation script compatible with macOS
The shell expansion syntax used in the run_node script was not handled properly
by the bash shell shipped with macOS. In particular, it was not able to handle
range expressions involving interpolated vars:

cp foo/{$FIRST_INDEX..$LAST_INDEX} ...

Dustin Brody 46b4154ce8 begin 0.6.0 (#256)
* begin 0.6.0: new get_domain/increase_balance/reduce_balance, BeaconState.validator_balances -> BeaconState.balances, some renamed constants, transaction processing changes, SlashableAttestation field name changes, 0.6.0 get_beacon_proposer_index always uses given state's slot, update tests subrepo

* mark get_bitfield_bit/bls_verify_multiple/stat-list-lengths/is_active_validator/is_surround_vote/slot_to_epoch/int_to_bytes/etc as unchanged in 0.6.0; rm Eth1DataVote/maybe_reset_eth1_period and thus adjust expected tree hash test results

Dustin Brody c53de3e550 Caching updates/refactoring & state_sim defaults updates (#235)
* rm now-superceded shuffling cache (shuffling is only called from get_crosslinks), which was badly architected due to trying to exist in state; rm one more vestige of previous light-client regime (one more to go, from datatypes)

* fix wrong shuffling list size (active validator size, not validator size) to make consistent with 0.5.1 (will be inconsistent with testnet0); fix typo and change defaults in state_sim

* doAssert a couple of constant relationships necessary to avoid underflow; rm non-spec, unused helper function get_new_recent_block_roots

* refactor separate crosslink_committee_cache and winning_root_participants_cache(s) into StateData object; remove last vestige of previous shuffling cache

* separate out caching parts of StateData to new StateCache object

a network running with a different number of shards).

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
