6617ad9531 Refactored finalization state. 
1. Removes state variables:
   - totalWeightedStakeThisEpoch
   - totalFeesCollectedThisEpoch
   - numActivePoolsThisEpoch

2. No longer indexes by epoch % 2

3. Renamed event StakingPoolActivated → StakingPoolEarnedRewards.

4. Renamed structs:
   - ActivePool → PoolStats. This holds stats for a pool that earned rewards.
   - UnfinalizedState → AggregatedStats. This aggregates stats from the former struct.

Make wrappers small again (#2243) 
* introduce --debug option to abi-gen and remove debug functions from @0x/abi-gen-wrappers
* make evmExecAsync protected; ignore deployedBytecode in doc comment
* trim deployedBytecode so it's undefined unless a contract has pure functions
* remove validateAndSendTransactionAsync
* Create `AwaitTransactionSuccessOpts` and `SendTransactionOpts` types 
* Remove duplicate types `IndexedFilterValues`, `DecodedLogEvent`, `EventCallback` from `@0x/base-contract`

54a03eacd6 @0x/contracts-staking: Refactor MixinCumulativeRewards and MixinStakingPoolRewards to better encapsulate cumulative rewards. 
`@0x/contracts-staking`: Make sure we don't overwrite an existing CR.
`@0x/contracts-staking`: Remove the need to initialize cumulative rewards when creating a pool.
`@0x/contracts-staking`: Just return an empty CR in `_getCumulativeRewardAtEpoch()` if one can't be found.
