[Beta] Backports (#7945 )

* ECIP 1041 - Remove Difficulty Bomb (#7905) Enable difficulty bomb defusion at block: - 5900000 on Ethereum Classic mainnet, - 2300000 on morden testnet. Reference: https://github.com/ethereumproject/ECIPs/blob/master/ECIPs/ECIP-1041.md * spec: Validate required divisor fields are not 0 (#7933) * Add validate_non_zero function It's used to validate that a Spec's uint field used as a divisor is not zero. * Add deserialize_with to gas_limit_bound_divisor Prevents panics due to divide-by-zero on the gas_limit_bound_divisor field. * Add deserialize_with to difficulty_bound_divisor Prevents panics due to divide-by-zero on the difficulty_bound_divisor field. * Add validate_optional_non_zero function Used to validate Option<Uint> divisor fields. * Use deserialize_with on optional divisor fields. * Add #[serde(default)] attribute to divisor fields When using `#[serde(deserialize_with)]`, `#[serde(default)]` must be specified so that missing fields can be deserialized with the deserializer for `None`. * Kovan WASM fork code (#7849) * kovan fork code * introduce ethcore level vm_factory and let it fail * fix json tests * wasmcosts as option * review changes * wasm costs in parser * fix evm tests * review fixes * fix test * remove redundant json field

I've enabled Whisper on a custom test network and inserted traces into Whisper handler implementation (Network<T> and NetworkProtocolHandler for Network<T>) and I noticed that the handler was never invoked. After further research on this matter, I found out that AttachedProtocol's register function does nothing: https://github.com/paritytech/parity/blob/master/sync/src/api.rs#L172 but there was an implementation originally: 99075ad#diff-5212acb6bcea60e9804ba7b50f6fe6ec and it did the actual expected logic of registering the protocol in the NetworkService. However, as of 16d84f8#diff-5212acb6bcea60e9804ba7b50f6fe6ec ("finished removing ipc") this implementation is gone and only the no-op function is left. Which leads me to a conclusion that in fact Whisper's handler never gets registered in the service and therefore two nodes won't communicate using it. Solution: Resurrect original non-empty `AttachedProtocols.register` implementation Resolves #7566 * Fix Temporarily Invalid blocks handling (#7613) * Handle temporarily invalid blocks in sync. * Fix tests.	2018-01-23 12:32:34 +01:00
