* parity-version: betalize 2.0
* Multiple improvements to discovery ping handling (#8771)
* discovery: Only add nodes to routing table after receiving pong.
Previously the discovery algorithm would add nodes to the routing table
before confirming that the endpoint is participating in the protocol. This
now tracks in-flight pings and adds to the routing table only after receiving
a response.
* discovery: Refactor packet creation into its own function.
This function is useful inside unit tests.
* discovery: Additional testing for new add_node behavior.
* discovery: Track expiration of pings to non-yet-in-bucket nodes.
Now that we may ping nodes before adding to a k-bucket, the timeout tracking
must be separate from BucketEntry.
* discovery: Verify echo hash on pong packets.
Stores packet hash with in-flight requests and matches with pong response.
* discovery: Track timeouts on FIND_NODE requests.
* discovery: Retry failed pings with exponential backoff.
UDP packets may get dropped, so instead of immediately booting nodes that fail
to respond to a ping, retry 4 times with exponential backoff.
* !fixup Use slice instead of Vec for request_backoff.

* Completely remove all dapps struct from rpc
* Remove unused pub use
* `evm bench` fix broken dependencies (#9134)
* `evm bench` use valid dependencies
Benchmarks of the `evm` used stale versions of a couple a crates that
this commit fixes!
* fix warnings
* Update snapcraft.yaml (#9132)
* Allow post-homestead forks to be specified in CommonParams
* Fix all json configs
* Fix test in json crate
* Fix test in ethcore
* Fix all chain configs to use tabs
Given we use tabs in .editorconfig and the majority of chain configs.
This change is done in Emacs using `mark-whole-buffer` and `indent-region`.
* move common forks and parameters to common params
* port specs over to new format
* fix RPC tests
* parity-machine skeleton
* remove block type
* extract out ethereum-specific methods into EthereumMachine
* beginning to integrate Machine into engines. dealing with stale transitions in Ethash
* initial porting to machine
* move block reward back into engine
* abstract block reward logic
* move last hash and DAO HF logic into machine
* begin making engine function parameters generic
* abstract epoch verifier and ethash block reward logic
* instantiate special ethereummachine for ethash in spec
* optional full verification in verify_block_family
* re-instate tx_filter in a way that works for all engines
* fix warnings
* fix most tests, further generalize engine trait
* uncomment nullengine, get ethcore tests compiling
* fix warnings
* update a bunch of specs
* re-enable engine signer, validator set, and transition handler
* migrate basic_authority engine
* move last hashes into executedblock
* port tendermint
* make all ethcore tests pass
* json-tests compilation

* fix broken import
* fix transaction verification for pre-homestead
* Ethereum Classic Monetary Policy
Create a new parameter `ecip1017EraRounds`. When the block number
passes one era rounds, the reward is reduced by 20%.
See https://github.com/ethereumproject/ECIPs/blob/master/ECIPs/ECIP-1017.md
* Update rewards for uncle miners for ECIP1017
In the monetary policy, the rewards are changed from "up to 7/8 of the
reward" to "1/32 of the reward".
* Fix an off-by-one error in ECIP1017 era calculation
According to
https://github.com/ethereumproject/ECIPs/blob/master/ECIPs/ECIP-1017.md,
when in block number 5,000,000, it should still be in Era 1 (which in
our code `era == 0`). So we need to check whether the `rem` equals to
zero and act accordingly when calculating the era.
* `ecip1017_era_rounds` missing from EthashParams when run in build bot
* strip out ecip1017_eras_block_reward function and add unit test
* The front-end for each hard-fork, also EIP-160.
* Address EIP161 a/c
* Include EIP-161b
* EIP-161 part d.
* Fix test build.
* Fix one test, add another.
* Fix use of bloom & renaming.
* Initial groundwork for EIP-155
* Fix minor bug.
* Fix all tests finally.
* Rest of EIP-155.
* Add tests for EIP-155 algorithm.
Update transaction tests validation.
* Minor reformat.
* Address grumbles.
* Remove unused code.
* Fix SUICIDE gas mechanism and add consensus tests.
* Remove commented code.
* Set Frontier hardfork block number
* Fix warning.
* Transaction tests,
* Add Ethereum Classic support
(Rename homestead-dogmatic -> classic)
* Additional change needed.
* More needed changes.
* Separate database path for known forks.
* Address minor grumble.
