b457f46c81 ethash: implement Progpow (#9762)
* ethash: initial implementation of progpow

* progpow: use wrapping arithmetic

* progpow: cleanup comments

* progpow: fix keccak_f800

* progpow: reorder definitions

* progpow: general fixing

* progpow: add basic tests from geth

* progpow: generate c_dag and add test

* progpow: fix progpow_init and progpow_loop

* progpow: fix and add new test

* progpow: tabify

* progpow: add shared testvectors from geth and aleth

* progpow: add benchmarks

* progpow: don't read bytes from dag

* ethash: use criterion for progpow benchmarks

* progpow: dont borrow hash on fnv1a_hash

* progpow: don't borrow operand on progpow merge

* progpow: hardcode dag lookup function

we only support light verification anyway

* progpow: read double words directly from the dag

* progpow: inline some small functions

* progpow: remove some bounds checking from the main loop

* progpow: remove unreachable match cases

* progpow: remove bounds check in keccak_f800_round

* progpow: fix ptr::swap

* progpow: force loop unroll in keccak_f800_round

* progpow: remove unnecessary branching in progpow_loop

* progpow: force loop unroll in fill_mix

* progpow: silence unused warning

* progpow: dont run last keccak_f800_round out of the loop

rustc generates the same assembly, it unrolls the loop

* progpow: fix output of keccak_f800_short

* ethcore: support progpow in ethash engine

* ethash: fix typo

* ethcore, ethash: fix tests

* json: fix ethash spec tests

* ethash: update quick_get_difficulty for progpow

* ethash: drop light cache on progpow transition block

* ethash: fix quick_get_difficulty tests

* progpow: update to spec v0.9.0

* progpow: update to spec v0.9.1

* progpow: update to spec v0.9.2

* ethash: rename progpow benchmarks

* fix Cargo.lock bad merge

* ethash: only export modules for benchmarks

* ethash: progpow: remove unsafe unchecked indexing

* ethash: create enum for pow algorithm

* ethash: box the progpow cdag

* ethash: skip slow progpow test vectors on ci

* ethash: don't skip progpow test vectors

they don't take too long when running in release mode which is the case
for CI.

* ethash: progpow: update copyright date

e84f308264 Fix unsoundness in ethash's unsafe code (#6140)
* Fix benchmarks

* Fix unsoundness in uses of unsafety

* Remove most uses of unsafe indexing and ptr::copy_nonoverlapping

This commit also includes a completely absurd optimisation that I
promise is an honest win. You can check the benchmarks, I barely
believe it myself.

* Add safety comment

* Add more safety comments

2cc1c92901 Unroll one more loop
I also tried unrolling the 256-iteration loop further below, but it actually caused a
slowdown (my guess is either branch prediction stopped kicking in or the instruction
cache was being maculated).
