235bc6a2cb Statediffing geth
* Write state diff to CSV (#2)

* 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

* Apply goimports to statediff

* Apply gosimple changes to statediff

* Gracefully exit geth command(#4)

* Statediff for full node (#6)

* Open a trie from the in-memory database

* Use a node's LeafKey as an identifier instead of the address

It was proving difficult to find look the address up from a given path
with a full node (sometimes the value wouldn't exist in the disk db).
So, instead, for now we are using the node's LeafKey with is a Keccak256
hash of the address, so if we know the address we can figure out which
LeafKey it matches up to.

* Make sure that statediff has been processed before pruning

* Use blockchain stateCache.OpenTrie for storage diffs

* Clean up log lines and remove unnecessary fields from builder

* Apply go fmt changes

* Add a sleep to the blockchain test

* refactoring/reorganizing packages

* refactoring statediff builder and types and adjusted to relay proofs and paths (still need to make this optional)

* refactoring state diff service and adding api which allows for streaming state diff payloads over an rpc websocket subscription

* make proofs and paths optional + compress service loop into single for loop (may be missing something here)

* option to process intermediate nodes

* make state diff rlp serializable

* cli parameter to limit statediffing to select account addresses + test

* review fixes and fixes for issues ran into in integration

* review fixes; proper method signature for api; adjust service so that statediff processing is halted/paused until there is at least one subscriber listening for the results

* adjust buffering to improve stability; doc.go; fix notifier
err handling

* relay receipts with the rest of the data + review fixes/changes

* rpc method to get statediff at specific block; requires archival node or the block be within the pruning range

* fix linter issues

* include total difficulty to the payload

* fix state diff builder: emit actual leaf nodes instead of value nodes; diff on the leaf not on the value; emit correct path for intermediate nodes

* adjust statediff builder tests to changes and extend to test intermediate nodes; golint

* add genesis block to test; handle block 0 in StateDiffAt

* rlp files for mainnet blocks 0-3, for tests

* builder test on mainnet blocks

* common.BytesToHash(path) => crypto.Keaccak256(hash) in builder; BytesToHash produces same hash for e.g. []byte{} and []byte{\x00} - prefix \x00 steps are inconsequential to the hash result

* complete tests for early mainnet blocks

* diff type for representing deleted accounts

* fix builder so that we handle account deletions properly and properly diff storage when an account is moved to a new path; update params

* remove cli params; moving them to subscriber defined

* remove unneeded bc methods

* update service and api; statediffing params are now defined by user through api rather than by service provider by cli

* update top level tests

* add ability to watch specific storage slots (leaf keys) only

* comments; explain logic

* update mainnet blocks test

* update api_test.go

* storage leafkey filter test

* cleanup chain maker

* adjust chain maker for tests to add an empty account in block1 and switch to EIP-158 afterwards (now we just need to generate enough accounts until one causes the empty account to be touched and removed post-EIP-158 so we can simulate and test that process...); also added 2 new blocks where more contract storage is set and old slots are set to zero so they are removed so we can test that

* found an account whose creation causes the empty account to be moved to a new path; this should count as 'touching; the empty account and cause it to be removed according to eip-158... but it doesn't

* use new contract in unit tests that has self-destruct ability, so we can test eip-158 since simply moving an account to new path doesn't count as 'touchin' it

* handle storage deletions

* tests for eip-158 account removal and storage value deletions; there is one edge case left to test where we remove 1 account when only two exist such that the remaining account is moved up and replaces the root branch node

* finish testing known edge cases

* add endpoint to fetch all state and storage nodes at a given blockheight; useful for generating a recent atate cache/snapshot that we can diff forward from rather than needing to collect all diffs from genesis

* test for state trie builder

* if statediffing is on, lock tries in triedb until the statediffing service signals they are done using them

* fix mock blockchain; golint; bump patch

* increase maxRequestContentLength; bump patch

* log the sizes of the state objects we are sending

consensus/clique, core: API cleanup (#23100)
This removes some code:

- The clique engine calculated the snapshot twice when verifying headers/blocks.

- The method GetBlockHashesFromHash in Header/Block/Lightchain was only used by tests. It
  is now removed from the API.
  
- The method GetTdByHash internally looked up the number before calling GetTd(hash, num).
  In many cases, callers already had the number, and used this method just because it has a
  shorter name. I have removed the method to make the API surface smaller.

eth/tracers: avoid unsyncronized mutations on trie database (#23632)
This PR fixes an issue in traceChain, where the statedb Commit operation was performed asynchronously with dereference-operations agains the underlying trie.Database instance. Due to how the reference counting works within the trie database (where parent count is recursively updated when new parents are added), doing dereferencing in the middle of Commit can cause the refcount to become wrong, leading to an inconsistent state. 

This was fixed by doing Commit/Deref from the same routine.

core,eth: call frame tracing (#23087)
This change introduces 2 new optional methods; `enter()` and `exit()` for js tracers, and makes `step()` optiona. The two new methods are invoked when entering and exiting a call frame (but not invoked for the outermost scope, which has it's own methods). Currently these are the data fields passed to each of them:

    enter: type (opcode), from, to, input, gas, value
    exit: output, gasUsed, error

The PR also comes with a re-write of the callTracer. As a backup we keep the previous tracing script under the name `callTracerLegacy`. Behaviour of both tracers are equivalent for the most part, although there are some small differences (improvements), where the new tracer is more correct / has more information.

core: fix pre-check for account balance under EIP-1559 (#23244)
When processing a transaction with London fork rules, EIP-1559 mandates
checking that the sender must have sufficient balance to cover gas * gasFeeCap.

In the EIP's pseudocode, this check happens after the value transferred by the
transaction has already been deducted. However, in go-ethereum, the balance
has not yet been updated when the check happens, and therefore needs to be
added explicitly.

eth/fetcher, trie: unit test reliability fixes (#23020)
Some tests take quite some time during exit, which I think causes
some appveyor fails like this:

    https://ci.appveyor.com/project/ethereum/go-ethereum/builds/39511210/job/xhom84eg2e4uulq3

One of the things that seem to take time during exit is waiting
(up to 100ms) for the syncbloom to close. This PR changes it to use
a channel, instead of looping with a 100ms wait.

This also includes some unrelated changes improving the reliability of
eth/fetcher tests, which fail a lot because they are time-dependent.

eth/downloader: increase downloader block body allowance (#23074)
This change increases the cache size from 64 to 256 Mb for block bodies.
Benchmarks have shown this to be one bottleneck when trying to achieve
higher download speeds.

The commit also includes a minor optimization for header inserts in package
core: previously, the presence of headers in the database was checked for
every header before writing it. With the change, if one header fails the
presence check, all subsequent headers are also assumed to be missing.
This is an improvement because in practice, the headers are almost always
missing during sync.
