rename parameter

In this case, the naming of "extapi" might create some confusion. Although it represents an External Signer Backend, its name could be mistaken for an API. In reality, it is a backend instance used for communicating with external signers. A better naming choice could be "extBackend" or "externalBackend" to more accurately describe that it is a backend instance rather than an API.

This PR modifies the interface for the results of `debug_traceBlock` and `debug_traceCall` by adding the `txHash`, allowing users to identify which transaction's trace result corresponds to.

rpc: use atomic type

* all: remove ethash pow, only retain shims needed for consensus and tests

* all: thank you linter

* all: disallow launching Geth in legacy PoW mode

* cmd/env/internal/t8ntool: remove dangling ethash flag

This adds logic to prepend 'M' or 'E' to Solidity identifiers when they would
otherwise violate Go identifier naming rules.

Closes #26972

Fixes a discrepancy between source and generated files, which was introduced when ExcessDataGas was added in https://github.com/ethereum/go-ethereum/pull/27046. 

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 changes TALKREQ message processing to run the handler on separate goroutine,
instead of running on the main discv5 dispatcher goroutine. It's better this way because
it allows the handler to perform blocking actions.

I'm also adding a new method TalkRequestToID here. The method allows implementing
a request flow where one node A sends TALKREQ to another node B, and node B later
sends a TALKREQ back. With TalkRequestToID, node B does not need the ENR of A to
send its request.

Makes the `geth account ... ` commands usable even if a geth-process is already executing, since the account commands do not read the chaindata, it was not required for those to use the same locking mechanism.

* trie: add node type common package

In trie/types package, a few node wrappers are defined, which will be used
in both trie package, trie/snap package, etc. Therefore, a standalone common
package is created to put these stuffs.

* trie: rename trie/types to trie/trienode

eth: fix crash on querying nil finalized block

This is a breaking GraphQL API change. All numeric values are now encoded as
hex strings. The motivation for this change is matching JSON-RPC outputs more
closely.

Numbers in query parameters are accepted as both decimal integers and hex strings.

In this PR, all TryXXX(e.g. TryGet) APIs of trie are renamed to XXX(e.g. Get) with an error returned.

The original XXX(e.g. Get) APIs are renamed to MustXXX(e.g. MustGet) and does not return any error -- they print a log output. A future PR will change the behaviour to panic on errorrs.
