This commit does the following:
- Prevent overflow in `verify_timestamp()` by not adding `now` to found faulty timestamp
- Use explicit `CheckedSystemTime::checked_add` to prevent potential consensus issues because SystemTime is platform
depedent
- remove `#[cfg(not(time_checked_add))]` conditional compilation
* Add a way to signal shutdown to snapshotting threads
* Pass Progress to fat_rlps() so we can abort from there too.
* Checking for abort in a single spot
* Remove nightly-only weak/strong counts
* fix warning
* Fix tests
* Add dummy impl to abort snapshots
* Add another dummy impl for TestSnapshotService
* Remove debugging code
* Return error instead of the odd Ok(())
Switch to AtomicU64
* Use fewer threads for snapshotting
When taking a snapshot the current default number of threads is equal to half the number of **logical** CPUs in the system. On HT enabled CPUs this value seems a bit high, e.g. 6 snapshotting threads on a 6/12 core/hyperthread CPU. Maybe a better default value is half the number of physical cores?

* Use Drop to shutdown stepper thread
Make period == 0 an error and remove the Option from step_service
* Remove StepService
Remove StepService and spawn the stepping thread in `Clique::new()`. Don't store the thread handle and instead trust the `AtomicBool` to signal shutdown time.
Don't check for `period > 0`: we assume a valid chainspec file.
* Don't shutdown the stepper thread at all, just let it run until exit
Also: fix a few warnings and tests
* Put kvdb_memorydb back
* Warn&exit when engine is dropped
Don't sleep too long!
* Don't delay stepping thread
* Better formatting
* Remove annoying compiler warnings
* Fix compiler warning (that will become an error)
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.
* Don't panic if extra_data is longer than VANITY_LENGTH
Seems like `extra_data().len()` can be longer than 32 (was 39 here) so this fixes that panic.
