* [ethash]: validate `ecip1017EraRounds` non-zero
When `ecip1017EraRounds` ethash will divide by zero.
This commit ensures that the chainspec deserialization fails and
gives a better error message.

This adds block reward contract config to ethash. A new config `blockRewardContractCode` is also added to both Aura and ethash. When specified, it will execute the code directly and overrides any `blockRewardContractAddress` config. Having this `blockRewardContractCode` config allows chains to deploy hard fork by simply replacing the current config value, without the need from us to support any `multi` block reward scheme.

* don't append `gpl license` in files with other lic

* remove duplicate header
* rebase nit
* 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`.
* 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`.

* 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 support for Expanse.
* Fix build.

* Fix exp json again.
* Fixed test
* Fix tests.
* Minor additions to allow resetting of code.
* Add test.
* Provisional DAO hard-fork proposal.
* Change to reflect latest HF spec.
* Include extradata restrictions and overrides.
* Introduce new tests.
* Update tests to new spec format.
* Allow JSON chain spec fields to be optional.
* Remove superfluous definitions. Fix overflow risk.
* Fix build.
* Add missing file.
* Remove old flag.
* Update to latest address set.
* Update tests and test spec to latest.
Change the mining default to release only on own transactions.
Soft-fork will remain default behaviour, but you can now disable
either the whole mechanism (you'll lose money if you mine with this
when the majority network doesn't) or just vote against it but
otherwise go with the flow.
* Firt commit.
* First non-functional but correct implementation of BasicAuthority.
Still needs:
- Sealing infrastructure.
* Punch a hole to give miner access to key store.
* Fix test built.
* Basic version of synchronous mining.
This will seal a block whenever a new transaction comes through.
To be made better we need a timer which will wait for one second after the
last block before sealing a new one - better still would be to cooperatively
interleave blocks with other sealing nodes.
* Add tests.
* Fix minor issues from repotting.
* Address grumbles.
