Wei Tang 18fa1d15ce Cumulative fixes to make working with consensus-pow easier (#3617)
* consensus-pow: add difficulty data to auxiliary

* Timestamp api

* Implement FinalityProofProvider for ()

* Add DifficultyApi

* Remove assumption that Difficulty is u128

* Use a separate trait for add instead of hard-code it as Saturating

* Some convenience functions to work with PowVerifier

* Try to fix mining unstability

* Fix generic resolution

* Unused best_header variable

* Fix hash calculation

* Remove artificial sleep

* Tweak proposer waiting time

* Revert sleep removal

The reason why it was there is because when mine_loop returns, it means an error
happened. In that case, we'd better sleep for a moment before trying again,
because immediately trying would most likely just fail.

* Pass sync oracle to mining

So that it does not mine when major syncing

* Expose build time as a parameter

Instead of hardcode it as previously 100ms.

* Update lock file

* Fix compile

* Support skipping check_inherents for ancient blocks

For PoW, older blocks are secured by the work, and can mostly be considered to
be finalized. Thus we can save both code complexity and validation time by
skipping checking inherents for them.

* Move difficulty fetch function out of loop

To make things faster

* Remove seed from mining

Each engine can use its own Rng source.

* Better comments

* Add TotalDifficulty definition for U256 and u128

* Update core/consensus/pow/src/lib.rs

* Rename TotalDifficulty::add -> increment

* Use SelectChain to fetch the best header/hash

* Update lock file

DemiMarie-parity 62b97a090d Upgrade dependencies whenever “easy” (#3556)
* Update all dependencies

* Upgrade dependencies whenever “easy”

“easy” means that there are no major changes required.

* Fix build and bump paste dependency to 0.1.6

* Remove dead code

* Re-add = dependency for futures-preview

* Add missing std features for runtime-io

* Remove git dependencies

as updated versions have been published to crates.io

* try to debug bug

* For sr-io, "std" should imply "no_oom" and "no_panic_handler".

Otherwise, rustc complains (correctly) about duplicate lang items.

* Add missing "runtime-io/std" features

* Fix compilation errors

* Prevent duplicate lang items

Rust does not allow duplicate lang items.  When compiled without the
`std` feature, `sr-io` defines two lang items.  Therefore, `sr-io`
compiled without `feature = "std"` must not be linked with `std`.

However, `pwasm-utils` and `wasmi-validation` both bring in `std` unless
compiled with `default-features = "false"`.  This caused a duplicate
lang item error.  Building both with `default-features = "false"`
prevents this error.  When building with `feature = "std"`, they should
both be built with the `std` feature, so this feature needs to be
explicitly depended on.

* Bump `impl_version`

* Make tests pass

Three tests used 1 less gas than they had previously.

* Try to un-break build

* Add a Cargo.lock file

* Revert offchain code

* Revert "Revert offchain code"

This reverts commit d216d08cc6ca0344614669c1d24cde3aa5c0d4e2.

* Don’t try to send a body with a GET request

without adding a Transfer-Encoding or Content-Length header.

This has always been wrong, but hyperium/hyper#1925 hid the bug until
hyper was upgraded to 0.12.35.

* Change some more GET requests to POST requests

* Fix excess line width and remove an `extern crate`

* Delete commented-out extern crate

* Fix regression in Cargo.toml files

dev-dependencies need `default-features = false`, too.

* Bump parity-wasm dependency

* Bump `futures-preview`

Wei Tang ece0b57d8d Consensus: Proof of Work (#3473)
* consensus-pow: init primtives and verifier

* consensus-pow: add total difficulty auxiliary

* consensus-pow: implement total difficulty chain selection

* consensus-pow: implement pow import queue

* consensus-pow-primitives: add mine into PowApi

* consensus-pow: implement mining

* Update lock file

* Style fixes

No run-on expressions allowed.

* consensus-pow: refactor register_pow_inherent_data_provider

* consensus-pow: make PowApi::mine yieldable

* consensus-pow: better mining loop

* Add missing license header

* consensus-pow-primitives: clarify the meaning of None for PowApi::verify

* consensus-pow: changing total difficulty addition to use saturating add

* consensus-pow: change mine-loop error to log on error! level

* consensus-pow: allow inserting arbitrary preruntime digest for pow

The preruntime digest can be intepreted by the runtime as the block author/coinbase.

* Fix line width

* More line width fixes

* consensus-pow: separate difficulty, verify API

This makes it more apparent that currently in PoW engine, `difficulty` should
be input, not output.

* srml-pow: basic blake2 algo example

* srml-pow-average-span: make it not require genesis config

* srml-pow: add support for authorship

* Missing license headers

* consensus-pow: PowAlgorithm trait generalization

* Missing docs for consensus-pow

* More docs

* node-runtime: bump impl_version

* Add rationale for difficulty type

* consensus-pow: refactor aux_key
