vbuterin c764202a57 Slashing penalty calculation change (#1217) 
If the exit queue is very long, then a validator may take many months to exit. With the code as currently written, however, self-slashing is a potentially lucrative route to get one's money out faster, because one can exit in 36 days.

This PR changes it so that slashing can only extend your withdrawal time, not contract it. Also, instead of the slashed balances used to calculate one's slashing penalty being those in `[withdrawal - 54 days ... withdrawal - 18 days]`, we now run the penalization algorithm once every 36 days that a validator is slashed but not withdrawn, so that it covers the 36-day period where the validator was actually slashed.  It also moves the minimum slashing penalty to the `slash_validator` function so that it is only applied once.

We also simplify the `slashed_balances` logic to be per-epoch.

Clarify `get_randao_mix` accessor 
We avoid a genesis underflow by taking the randao epoch in `generate_seed` to be `+ EPOCHS_PER_HISTORICAL_VECTOR`.

This conflicts with the expected epoch bounds noted  in `get_randao_mix` and this PR attempts to clarify the situation by leaving a note.

Diederik Loerakker d587c4fe61 Critical fix: introduce back total-value check (#1220) 
This was dropped in a376b6607f, as improvement in dust checking.
Now that dust-checking is done, we still need to check if the sender has the minimum value, as decrease balance just clips to 0.
See be86f966f8 for older dust-creation problem work around, which was dropped in the above.

The bug enabled you to transfer your full balance to someone else, and pay the same amount in fee, possibly to a puppet proposer to collect back funds.
Effectively enabling printing of money. Silly bug, good to fix and introduce tests for.

The comment seems to imply conjunction over each case, but the code implies disjunction; at the very least it is ambiguous.

Fix #1173 
The bug is that it's possible to include a participating validator which has custody bit one *without* specifying that validator in `attestation.aggregation_bitfield`. In other words, we want to check that every bit in `custody_bitfield` is zero whenever the corresponding bit in `aggregation_bitfield` is zero. Well spotted @protolambda

Tweak inclusion delay rewards and set BASE_REWARD_FACTOR 
Substantive changes:

1) Split the inclusion delay reward between attester and proposer to add up to at most one base reward. This is analogous to the reward logic in `slash_validator`, and makes the `BASE_REWARDS_PER_EPOCH` constant include proposer rewards.
2) Double `BASE_REWARD_FACTOR` to 2^6 (addressing item 4 in #1054). When the total effective balance is 2^17 ETH then maximum annual issuance is a bit below 2^21 ETH. Maximum annual issuance happens when a) all validators make perfect attestations (matching source, target, head, as well as consistent crosslink data), b) all attestations are included as fast as possible (in particular, no skip blocks), and c) there are no slashings.

```python
BASE_REWARD_FACTOR = 2**6
SLOTS_PER_EPOCH = 2**6
SECONDS_PER_SLOT = 6
BASE_REWARDS_PER_EPOCH = 5
GWEI_PER_ETH = 10**9
MAX_TOTAL_EFFECTIVE_BALANCE = 2**27 * GWEI_PER_ETH
TARGET_MAX_ISSUANCE = 2**21 * GWEI_PER_ETH

def integer_squareroot(n: int) -> int:
    """
    The largest integer ``x`` such that ``x**2`` is less than or equal to ``n``.
    """
    assert n >= 0
    x = n
    y = (x + 1) // 2
    while y < x:
        x = y
        y = (x + n // x) // 2
    return x

MAX_REWARDS_PER_EPOCH = MAX_TOTAL_EFFECTIVE_BALANCE * BASE_REWARD_FACTOR // integer_squareroot(MAX_TOTAL_EFFECTIVE_BALANCE) // BASE_REWARDS_PER_EPOCH
EPOCHS_PER_YEAR = 365.25*24*60*60 / (SECONDS_PER_SLOT * SLOTS_PER_EPOCH)
MAX_REWARDS_PER_YEAR = EPOCHS_PER_YEAR * MAX_REWARDS_PER_EPOCH * BASE_REWARDS_PER_EPOCH

print(MAX_REWARDS_PER_YEAR / TARGET_MAX_ISSUANCE)
```
