* port statediff from 9b7fd9af80/statediff/statediff.go; minor fixes
* integrating state diff extracting, building, and persisting into geth processes
* work towards persisting created statediffs in ipfs; based off github.com/vulcanize/eth-block-extractor
* Add a state diff service
* Remove diff extractor from blockchain
* Update imports
* Move statediff on/off check to geth cmd config
* Update starting state diff service
* Add debugging logs for creating diff
* Add statediff extractor and builder tests and small refactoring
* Start to write statediff to a CSV
* Restructure statediff directory
* Pull CSV publishing methods into their own file
* Reformatting due to go fmt
* Add gomega to vendor dir
* Remove testing focuses
* Update statediff tests to use golang test pkg
instead of ginkgo
- builder_test
- extractor_test
- publisher_test
* Use hexutil.Encode instead of deprecated common.ToHex
* Remove OldValue from DiffBigInt and DiffUint64 fields
* Update builder test
* Remove old storage value from updated accounts
* Remove old values from created/deleted accounts
* Update publisher to account for only storing current account values
* Update service loop and fetching previous block
* Update testing
- remove statediff ginkgo test suite file
- move mocks to their own dir
* Updates per go fmt
* Updates to tests
* Pass statediff mode and path in through cli
* Return filename from publisher
* Remove some duplication in builder
* Remove code field from state diff output
this is the contract byte code, and it can still be obtained by querying
the db by the codeHash
* Consolidate acct diff structs for updated & updated/deleted accts
* Include block number in csv filename
* Clean up error logging
* Cleanup formatting, spelling, etc
* Address PR comments
* Add contract address and storage value to csv
* Refactor accumulating account row in csv publisher
* Add DiffStorage struct
* Add storage key to csv
* Address PR comments
* Fix publisher to include rows for accounts that don't have store updates
* Update builder test after merging in release/1.8
* Update test contract to include storage on contract intialization
- so that we're able to test that storage diffing works for created and
deleted accounts (not just updated accounts).
* Factor out a common trie iterator method in builder
