vbuterin abed5ffdae Updated phase 1: fork choice rule (#586)
Adds the crosslink committee to the fork choice rule. This is useful because it means that even if a proposal committee is byzantine and attempts to prevent a crosslink via a "balance attack" (alternating between chain A and chain B being the canonical chain), the crosslink committee can force the equilibrium to flip to one side or the other.

vbuterin 086df84bdc
Attestation data contains latest crosslink, not just latest crosslink data
The reason to do this is that it makes it calculable from inside an attestation how many epochs the attestation spans over, which is needed for proof of custody reasons. It's a relatively small change and so arguably easier to do now than to do as a patch in phase 1.

Note that this changes the meaning of latest_crosslink.epoch, from the epoch when the latest crosslink was included to the epoch that the latest crosslink was for. This affects the line:

* `state.latest_crosslinks[shard].epoch > state.validator_registry_update_epoch` for every shard number `shard` in `[(state.current_epoch_start_shard + i) % SHARD_COUNT for i in range(get_current_epoch_committee_count(state))]` (that is, for every shard in the current committees)

But this may actually make it _more_ correct, as it means that in the case where >512 shards are processed per epoch, and so a committee from the previous epoch could get finalized in the current epoch, that would no longer count toward every shard having received a "new" crosslink.

Removes the source of the Vyper contract from the spec.
This change allows for easier maintenance of the code and the spec by
uncoupling them. Before any edit to either document resulted in having to
synchronize the other. By adding a reference to the canonical repo for the code
we avoid having to maintain a duplicate copy here.

SSZ list Merkle hashing change
The current spec is arguably inconsistent, in that if a set of N values gets chunked into M chunks where M is not an exact power of 2, the chunks between M and next_power_of_2(M) are filled with SSZ_CHUNK_SIZE zero bytes each, but the last chunk is not padded, and could be arbitrarily short (eg. if the values are 4 bytes and there are 257 of them, then that gets serialized into eight chunks chunks where the first four are 64 values each, the fifth is 4 bytes corresponding to the last value, and the last three chunks are SSZ_CHUNK_SIZE zero bytes). This PR fills every chunk up to exactly SSZ_CHUNK_SIZE bytes for consistency.

Remove the unnecessary double backticks on 'validator' in docstring.
The usual convention is that we mark function parameters in docstrings with
double backticks. There is no (longer a) parameter called 'validator' so we
update the docstring to conform to the convention.

Ben Edgington fb75c6dd55 Fix to verify bitfields and aggregate signature.
In blockprocessing, `crosslink_committee` is not defined. This is a fix.

In Phase 0 this check is redundant since we've already asserted that the
custody bitfield is all zero, but it will matter in later phases.

Remove exit counts
* Simplify by removing `exit_epoch` in `BeaconState` and `Validator`. (Also less storage for full nodes.)
* Replace with `exit_epoch` when ordering validator with withdrawal. Slight loss of granularity, but that's actually a good thing because it reduces the opportunity for manipulation by proposers.

Cleanup attestation inclusion logic
* (Logic change) Introduce invariant that attestations can be included for `EPOCH_LENGTH`.
* Simplify presentation by related checks into a single line.

Attester slashing fixes
* Fix bug whereby `intersection` (replaced by `slashable_indices `) could be non-empty, but no validator gets penalized because they were all already penalized.
* Rename `SlashableVote` to `SlashableAttestation` (for consistency with `Attestation`, and to avoid having "Vote" be a synonym of "Attestation").
* Rename `slot_included` to `inclusion_slot` for consistency with the `_slot` (and `_epoch`) postfix convention
* Homogenise ordering of fields in `Attestation` and `SlashableAttestation` objects (one has an `aggregation_bitfield` instead of the other's `validator_indices`).
* Homogenise ordering of fields in `Attestation` and `PendingAttestation` objects (one has an `aggregate_signature` instead of the other's `inclusion_slot`).
* Light presentation cleanup
