Optimizations:
- Previously, if a transaction was reverting, EstimateGas would exhibit worst-case behavior and binary search up to the max gas limit (~40 state-clone + tx executions). This change allows EstimateGas to return after only a single unconstrained execution in this scenario.
- Uses the gas used from the unconstrained execution to bias the remaining binary search towards the likely solution in a simple way that doesn't impact the worst case. For a typical contract-invoking transaction, this reduces the median number of state-clone+executions from 25 to 18 (28% reduction).
Cleanup:
- added & improved function + code comments
- correct the EstimateGas documentation to clarify the gas limit determination is at latest block, not pending, if the blockNr is unspecified.
This adds support for the "yParity" field in transaction objects returned by RPC
APIs. We somehow forgot to add this field even though it has been in the spec for
a long time.
This changes the eth_getProof method implementation to re-encode the requested
storage keys, canonicalizing them in the response. For backwards-compatibility reasons,
go-ethereum accepts non-canonical hex keys. Accepting them is fine, but we should
not mirror invalid inputs into the output.
Closes#27306

This removes the feature where top nodes of the proof can be elided.
It was intended to be used by the LES server, to save bandwidth
when the client had already fetched parts of the state and only needed
some extra nodes to complete the proof. Alas, it never got implemented
in the client.
Deserialize hex keys early to shortcut on invalid input, and re-use the account storageTrie for each proof for each proof in the account, preventing repeated deep-copying of the trie.
Closes#27308

RPC methods `eth_getHeaderBy*` returned a size value which was meant for internal
processes. Please instead use `size` field returned by `eth_getBlockBy*` if you're interested
in the RLP encoded storage size of the block.

* EstimateGas should use LatestBlockNumber by default
* graphql: default to use latest for gas estimation

Adds an optional config parameter to eth_call which allows users to override block context fields (same functionality that was added to traceCall in #24871)

This PR removes the Debug field from vmconfig, making it so that if a tracer is set, debug=true is implied.

Here, the core.Message interface turns into a plain struct and
types.Message gets removed.
This is a breaking change to packages core and core/types. While we do
not promise API stability for package core, we do for core/types. An
exception can be made for types.Message, since it doesn't have any
purpose apart from invoking the state transition in package core.
types.Message was also marked deprecated by the same commit it
got added in, 4dca5d4db7 (November 2016).
The core.Message interface was added in December 2014, in commit
db494170dc, for the purpose of 'testing' state transitions. It's the
same change that made transaction struct fields private. Before that,
the state transition used *types.Transaction directly.
Over time, multiple implementations of the interface accrued across
different packages, since constructing a Message is required whenever
one wants to invoke the state transition. These implementations all
looked very similar, a struct with private fields exposing the fields
as accessor methods.
By changing Message into a struct with public fields we can remove all
these useless interface implementations. It will also hopefully
simplify future changes to the type with less updates to apply across
all of go-ethereum when a field is added to Message.

This change adds a struct field EffectiveGasPrice in types.Receipt. The field is present
in RPC responses, but not in the Go struct, and thus can't easily be accessed via ethclient.

The execution-apis specification says that the full list of withdrawals should always be returned when requesting a block over RPC:
378c4304f7/src/schemas/block.yaml (L90-L94)
This change adopts the expected behavior.
This change implements withdrawals as specified in EIP-4895.

This PR changes the API so that uint64 is used for fork timestamps.
It's a good choice because types.Header also uses uint64 for time.

This PR removes the notion of fakeStorage from the state objects, and instead, for any state modifications that are needed, it simply makes the changes.
This changes the StorageTrie method to return an error when the trie
is not available. It used to return an 'empty trie' in this case, but that's
not possible anymore under PBSS.
This PR changes the pending tx subscription to return RPCTransaction types instead of normal Transaction objects. This will fix the inconsistencies with other tx returning API methods (i.e. getTransactionByHash), and also fill in the sender value for the tx.

This change makes eth_getProof and eth_getStorageAt return an error when
the argument contains invalid hex in storage keys.

This changes the CI / release builds to use the latest Go version. It also
upgrades golangci-lint to a newer version compatible with Go 1.19.
In Go 1.19, godoc has gained official support for links and lists. The
syntax for code blocks in doc comments has changed and now requires a
leading tab character. gofmt adapts comments to the new syntax
automatically, so there are a lot of comment re-formatting changes in this
PR. We need to apply the new format in order to pass the CI lint stage with
Go 1.19.
With the linter upgrade, I have decided to disable 'gosec' - it produces
too many false-positive warnings. The 'deadcode' and 'varcheck' linters
have also been removed because golangci-lint warns about them being
unmaintained. 'unused' provides similar coverage and we already have it
enabled, so we don't lose much with this change.
Some small fixes to get the existing debug methods to conform to the spec. Mainly dropping the encoding information from the method name as it should be deduced from the debug context and allowing the method to be invoked by either block number or block hash. It also adds the method debug_getTransaction which returns the raw tx bytes by tx hash. This is pretty much equivalent to the eth_getRawTransactionByHash method.
Because the goal of eth_createAccessList is providing the caller with the largest-possible
access list, it's generally not important that the gas limit used by the tracer will match the usage
of the call exactly. Avoiding the gas estimation step is a performance improvement. As long as the
call does not branch based on gas limit, the returned access list will be accurate.
