Beta 2.5.3 (#10776)
* ethcore/res: activate atlantis classic hf on block 8772000 (#10766)

* fix docker tags for publishing (#10741)

* fix: aura don't add `SystemTime::now()` (#10720)

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

* fix(extract `timestamp_checked_add` as lib)

* fix(whisper types): remove unused `EmptyTopics`

* fix(time-lib): feature-flag to use time-lib or std

This commit adds conditional compilation checks that falls back to `our time-lib` when
`time_checked_add` is not available in the standard library

Note, `time_checked_add` covers both `checked_add` and `checked_sub`

Implement len caching for parking_lot RwLock (#10032)

LenCachingMutex (#9988)
New util LenCachingMutex can be used in place of a Mutex, when working
with collections, or other types with a len() method. When
the Guard is dropped, the value returned from len() is stored
into an AtomicUsize and can be queried using load_len() without
needing to lock the Mutex. Implementations for ```Vec``` and
```VecDeque```.

Now used in [Verification](4ded4181a6/ethcore/src/verification/queue/mod.rs (L196)) so that calls to ```VerificationQueue.queue_info()```
no longer require locks.

a511264433 Implement NoProof for json tests and update tests reference (replaces #9744) (#9814)
* Update test reference.
Block test are really not working so I disabled a few by commenting
directly in source.

* Move ethtest commit cursor.

* Implements 'NoProof' engine from https://github.com/ethereum/tests/issues/464 .

Since tests has been regenerated those one were failing on block
difficulty check.

Update ethereum/tests, waiting for cost fix (block test are still
commented).

* Update tests submodule reference to latest (all test passing except an
identified case).
Fix block reward of constantinople json.

* Restore broken test by using old json tests files.

* Use CanonNoSeal instead of a custom engine, still have to include some
additional tests code.

* Gas upper limit check in json_chain test was bad, moving the test to
verification, the test is running in `verify_header_param`.
Note that test was previously only for ethash, and now for any engine.

* Restore old behavior (gas uper limit only for ethash engine), at the
cost of an additional trait method.

* Proper rpc test fix.

* Update tests submodule, add SStore bug tests.

* Fix json issue tabulation.
Update tests submodule to latest master (lot of new sstore tests
passing)

* Switch ethereum/tests to tag 6.0.0-beta.1 (no tests changes from latest
synch).

* Display hex with separator, use indirection instead of clone for copy
types.

3216b143c2 ethcore/VerificationQueue don't spawn up extra worker-threads when explictly specified not to (#9620)
* VerificationQueue don't spawn up extra threads

In the verification queue we spawn up worker threads to do the work.
However, if `num-verifiers` is specified we still spawn the maximum
number of threads which consume extra memory.

There is one catch though when `--scale-verifiers` is specified then
we can't do it because all threads are created upon initilization AFAIK.

In my opinion, is doesn't to use both `num-verifiers` and
`scale-verifiers` they are kind of contradictory!

* Fix nits in logic and add tests for verification

* refactor(verification queue) - rm hardcoded const

* Address grumbles in new tests
* Remove hardcoded `MAX_VERIFIERS` constant and replace it by relying
entirely on `num_cpu` crate instead inorder to support CPUs that have
more cores/logical cores

a04c5b180a Replace legacy Rlp with UntrustedRlp and use in ethcore rlp views (#8316)
* WIP

* 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

* Expect valid rlp in decode functions for now

* Replace spaces with tabs in new file

* Add doc tests for creating views with macro

* Update rlp docs to reflect removing of UntrustedRlp

* Replace UntrustedRlp usages in private-tx merge
