Remove placeholders 
Remove all custody and VDF placeholders (56 lines less!). A few notes on the placeholder fields and logic:

* All placeholder fields were dummy fields that can easily be restored in the phase 1 hard fork.
* One special case to the above is `custody_bit_0_validator_indices` in `SlashableVoteData` which was renamed to `validator_indices`. Renaming it back is *not* a spec change because SSZ field names are [no longer part of the spec](a9328157a8 (diff-8d8fe480a35579c7be2f976d9b321216)).
* The placeholder logic was written using generalised functions (e.g. `bls_verify_multiple` vs `bls_verify`, and `indices(slashable_vote_data)` vs `slashable_vote_data.validator_indices`). This generality was unnecessary because it was not triggered when all custody bits were 0. This means we can simplify the logic without being inconsistent with phase 1.

Rationale:

* Keep phase 0 (likely far harder to deliver than phase 1) as clean as possible
* Focus on upgrade paths and incremental releases
* Custody is still under research—keep the design space open

BLS-based RANDAO and custody (friendly to decentralised pools) 
Unlock decentralised pools using m-of-n threshold BLS signatures for both RANDAO and custody. We also simplify a bunch:

* Remove `randao_commitment` and `custody_commitment`
* Remove miscellaneous logic such as `repeat_hash`

(Side note: Dfinity seems to be working to reduce the communication complexity of BLS DKG (Distributed Key Generation) so validator pools should also benefit from that.)

Implement #459 
Contents:

* Peg entries and exits to epoch boundaries
* Add a store of historical active index roots
* Mix it into the randomness
* Remove the delta hash chain

Note that the actual light client implementation is beyond the scope of the spec.

[Note to reviewers: verify that the invariant added in the PR is correct]

Question:

* Do we want to also only store epoch-boundary randao values? I don't think we use the epoch-intermediate ones anywhere.....

Fix typo with initial generation of `latest_penalized_exit_balances` 
The spec as written is not valid python -- the generator of the list
comprehension must be iterable.

It looks like the author simply meant to `range` over the intended length.

This commit fixes the missing `range` operator

Truncate the index into the Merkle tree to bytes[8] 
The beacon chain expects a `uint64` in part to avoid big-int computation.
This commit updates the `Deposit` log so that it broadcasts data of the
appropriate size.

Jim Posen b25154c774 Correct references to sig scheme in beacon spec. 
BLS is the name of the signature scheme and BLS12-381 is the name of the
curve that it is defined over. So it is more correct to talk about a
"BLS signature/pubkey" rather than a "BLS12-381 signature/pubkey".

Reorder type so the ssz serialization matches other uses 
There is an order based on the Vyper deposit contract which should be maintained
here. There is also a reference to it when processing `Deposit` messages.

This commit corrects the order here so all serializations will match.

Fixes bugs with description of deposit verification. 
1. The order of the `deposit_data` serialization does not match the current
Vyper contract. The description now matches that serialization.

2. The `deposit.merkle_tree_index` was not being used (at least explicitly) so
the text now reflects which inputs are to be used for which parameters in the
pseudocode spec that follows.

3. There seems to be a bug where we want the initial leaf to be the `hash` of
the `DepositData`, not the data itself. The text now reflects this requirement.

Ben Edgington 994a42e6b1 Add getter to Vyper contract for Merkle branches 
Returns the Merkle branch for the leaf at index `index`. This getter provides
an alternative way for beacon chain proposers to access the Merkle tree of
deposits rather than being Ethereum 1.0 light clients. The method can be
called on a trusted Ethereum 1.0 archive node at specific past block numbers
to retrieve the Merkle branch needed to register a validator.

Fixes typo in `sorted` function. 
In keeping with the rest of the code in this document we adhere to valid Python
where possible.

The custom comparator keyword argument for `sorted` is `key` so this commit

Fixes bug with Merkle proof branch selection 
This code determines the order in which the next branch element and the
current value should be hashed to produce the parent node in the Merkle tree.

The existing code fails to verify branches constructed in the standard way.

This patch fixes the spec code so that it works properly by using an appropriate
parity calculation.

Example code here to illustrate it working:
