Fixes https://github.com/paritytech/parity-ethereum/issues/10648
I'm not sure this fix is Good™ but rustc seems happy enough.
There's a deeper issue which may or may not be related to this: the Engine is not shutdown properly and the `StepService` thread keeps running indefinitely after Ctrl-C (so `update_sealing()` is called repeatedly for 300sec). I don't think this is related to Clique as I've seen this happen on mainnet as well, but I wonder if the effects of it are worse for a PoA network where the node can create new blocks all on its own?
* Use saturating_sub
* WIP
* Fix warning, second attempt
The idea here is to avoid using `Arc::get_mut()` (which does not work: fails every time here) and instead trust `drop()` to do the right thing.
This is a conservative change. I think this can be reformed further, e.g. by `impl Drop for StepService` and halt the thread there, or even skip `join()`ing the thread entirely and trust the `AtomicBool` to signal shutdown. I also have doubts abut the `Option<StepService>`: seems a bit much to have an `Option` there and it makes things cumbersome.

Fix: new blocks notifications sometimes missing in pubsub RPC
Implement new struct to pass to `new_blocks()` with extra parameter - `has_more_blocks_to_import`, which was previously used to determine whether the notification should be sent. Now it's up to each implementation to decide what to do.
Updated all implementations to behave as before, except `eth_pubsub`, which will send notification even when the queue is not empty.

* aura: emit ancestry actions for finalizing blocks
* aura: refactor is_epoch_end to get finalized blocks as argument
* ethcore: add is_epoch_end_light method to Engine
The full client now tracks finality by querying the engine on each block import,
and it also persists the finalization state to the DB. For the light client
current it doesn't persist finality information and only keeps track of finality
for epoch signals, by calling `is_epoch_end_light`. This method implements the
previously existing logic of building finality for all the blocks in the current
epoch and then checking the finalized blocks against the transition store.
* ethcore: allow finalizing current block
* aura: fix construction of finality proof
* aura: fix warnings
- missing docs for is_epoch_end_light
- unused method unfinalized_hashes in RollingFinality
* aura: fix clone on copy types
* `ExecutionsRequest` from light-clients as read-only
This changes so all `ExecutionRequests` from light-clients are executed
as read-only which the `virtual``flag == true ensures.
This boost up the current transaction to always succeed
Note, this only affects `eth_estimateGas` and `eth_call` AFAIK.

Closes#9255
This PR also removes the limit of max 64 transactions per packet, currently we only attempt to prevent the packet size to go over 8MB. This will only be the case for super-large transactions or high-block-gas-limit chains.
Patching this is important only for chains that have blocks that can fit more than 4k transactions (over 86M block gas limit)
For mainnet, we should actually see a tiny bit faster propagation since instead of computing 4k pending set, we only need `4 * 8M / 21k = 1523` transactions.
Running some tests on `dekompile` node right now, to check how it performs in the wild.

* Replace Rlp with UntrustedRlp in views, explicity unwrap with expect
First pass to get it to compile. Need to figure out whether to do this or to propogate Errors upstream, which would require many more changes to dependent code. If we do this way we are assuming that the views are always used in a context where the rlp is trusted to be valid e.g. when reading from our own DB. So need to fid out whether views are used with data received from an untrusted (e.g. extrernal peer).
* Remove original Rlp impl, rename UntrustedRlp -> Rlp
* Create rlp views with view! macro to record debug info
Views are assumed to be over valid rlp, so if there is a decoding error we record where the view was created in the first place and report it in the expect
* Use $crate in view! macro to avoid import, fix tests
