…3506 (#3542)

As a first step in #3506, upgrade OpenEthereum from [pre-2.6.0](openethereum/openethereum@eed630a) (Jun 2019) to [2.6.2](https://github.com/openethereum/openethereum/releases/tag/v2.6.2) (Aug 2019).

OpenEthereum 2.6.2 is the last release that nearcore can currently pull in without build errors. Further upgrades will require code changes in near-evm-runner. (I'm working on those.)

The upstream diff from what we currently pull in compared to 2.6.2: openethereum/openethereum@eed630a...v2.6.2

* initial gas used in evm interpreter

* see what case in result

* atempt of return different gas left

* gas_left

* all gas metering works

* undo all debug prints

* revert is not considered as error until top level to calc revert gas left

* resolve all gas from revert

* cost hook for precompile functions

* basic evm gas counter

* got evm gas used in all tests

* count deploy evm code cost

* compiles

* wip measure functions

* fix deploy cost

* measure funcall cost, start adding contract function to know precompile function cost

* all cost countings except bn256 precompiled functions

* calc and deduct near gas from number given by evm gas

* address illia comments

* thread in prepaid function cost in evm

* fix random fee

* convert prepaid near gas to evm gas so evm gas convert to near wont overflow

* made mistake of reverse base cost and per_evm_gas cost, correct it

* wip measure evm include block cost, stuck in get account code hash same to EVM_CODE_HASH

* deploy contract total cost calc works

* fix small errors after resolve conflict

* deploy cost works, function cost is 0, debug

* evm cost of function call

* comment

* deduct action fee and todo on get correct evm addr to function call

* fix deploy evm addr

* correct deduct action receipt cost

* saturating sub

* adding warmup

* remove some debug prints

* costs counting only on recet sevm gas counter

* some fixes

* fix errors in semantic conflicts happens in merge

* delete

* nit

* nit

* nit

* nit

* refactor use test-utils.testlib to get evm contract addr

* evm deploy cost based on both evm gas and contract size

* lsq compiles

* lsq compiles

* my rust impl of 2d lsq, end result stable but lsq is incorrect

* simplify

* accurate evm deploy base cost, per evm gas and per byte

* fix deploy evm contract to all accounts nonce issue

* balancer contract binary suite

* evm precompile function per byte evm gas, but they are too small

* wire in evm gas per byte and update numbers

* avoid pay evm bootstrap fee when evm is not started

* do not measure action receipt fee for evm as they are deduct separately

* new numbers

* features for runtime-params-estimator

* evm features works in runtime-param-estimator

* undo debug print

* undo disable lto

As the next step in #3506, and following up from #3542, upgrade OpenEthereum from [2.6.2](https://github.com/openethereum/openethereum/releases/tag/v2.6.2) (Aug 2019) to [2.6.8](https://github.com/openethereum/openethereum/releases/tag/v2.6.8) (Dec 2019), the last release in the 2.6.x series.

This brings us up to par on the [Istanbul](https://eth.wiki/en/roadmap/istanbul) hard fork, which incorporated many EIPs, changing gas metering and adding a new precompile as well as two new opcodes:

- [EIP-152: Add BLAKE2 compression function `F` precompile](https://eips.ethereum.org/EIPS/eip-152)
- [EIP-1108: Reduce alt_bn128 precompile gas costs](https://eips.ethereum.org/EIPS/eip-1108)
- [EIP-1344: ChainID opcode](https://eips.ethereum.org/EIPS/eip-1344) (includes a new opcode: `CHAINID`)
- [EIP-1884: Repricing for trie-size-dependent opcodes](https://eips.ethereum.org/EIPS/eip-1884) (includes a new opcode: `SELFBALANCE`)
- [EIP-2028: Transaction data gas cost reduction](https://eips.ethereum.org/EIPS/eip-2028)
- [EIP-2200: Structured Definitions for Net Gas Metering](https://eips.ethereum.org/EIPS/eip-2200)

This PR includes an implementation of the `CHAINID` opcode. (The `SELFBALANCE` opcode doesn't need anything from our runtime.)

- BREAKING: Added `FunctionCallArgs` structure and changed function call args to require this input. It adds `4` bytes for the size of RLP encoded input before the input. Makes function_call args a standard borsh structure
- BREAKING: Updated `ViewCallArgs` to be standard borsh structure. Same `4` bytes in front of the input
- Fix: Updated gas accounting for view calls, meta calls, and fixed alias function call when counting gas.
- Added a bunch of TODO.  
- Refactor: Created enum for `Method` to be explicit about `method_name` and parse it only once.
- Refactor: Updated storage to avoid some key copies
- Refactored some duplicated code for converting interpreter call result
- Refactor: Removed some cloning from input 

# Test plan:
- standard unit test is still failing, probably because of the invalid solidity binary.

As the next step in #3506, and following up from #3542 and #3558, upgrade Parity Ethereum (now OpenEthereum) from [2.6.8] (Dec 2019) to [2.7.2] (Feb 2020), the last release in the 2.x series.

This harmonizes our dependency graph with upstream, fixing numerous build errors from the upgrade and eliminating multiple versions of the same crates. This concerns the [bn], [ethabi], [ethabi-contract], [ethabi-derive], [ethereum-types], [keccak-hash], [primitive-types], and [uint] crates as well as their transitive dependencies and their interdependencies.

The [near/bn] fork exists to upgrade [bn]'s [rand] dependency. That's necessary because of a particularly complex dependency issue (rust-random/rand#645) in old versions of rand. We will eliminate the fork going forward once upstream upgrades their dependency (I will open a pull request for them).

The upstream changelog for 2.7.2 is at: https://github.com/openethereum/openethereum/blob/v2.7.2/CHANGELOG.md

This fixes #3611. The regression was due to an invalid `zombieAttack.bin` imported in e350e29 (#3299). Hereby reverted to the original from cc4ec1f.

Additionally, this also removes an annoying build warning inadvertently introduced in 8a45140 (#3595).
