Here we add a Go API for running tracing plugins within the main block import process.
As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within
that file register your custom tracer implementation. Then recompile geth and select your tracer
on the command line. Hooks defined in the tracer will run whenever a block is processed.
The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of
requiring an interface, for several reasons:
- We plan to keep this API stable long-term. The core/tracing hook API does not depend on
on deep geth internals.
- There are a lot of hooks, and tracers will only need some of them. Using a struct allows you
to implement only the hooks you want to actually use.
All existing tracers in eth/tracers/native have been rewritten to use the new hook system.
This change breaks compatibility with the vm.EVMLogger interface that we used to have.
If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking
your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM.

This pull request introduces a database tool for inspecting the state history.
It can be used for either account history or storage slot history, within a
specific block range.
The state output format can be chosen either with
- the "rlp-encoded" values (those inserted into the merkle trie)
- the "rlp-decoded" value (the raw state value)
The latter one needs --raw flag.
This adds support for the Deneb beacon chain fork, and fork handling
in general, to the beacon chain light client implementation.

This changes makes it so that when `evm statetest` executes, regardless of whether `--json` is specified or not, the stateroot is printed on `stderr` as a `jsonl` line. This enables speedier execution of testcases in goevmlab, in cases where full execution op-by-op is not required.
Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths.
Package path implements utility routines for manipulating slash-separated paths.
The path package should only be used for paths separated by forward slashes, such as the paths in URLs
Here we add a beacon chain light client for use by geth.
Geth can now be configured to run against a beacon chain API endpoint,
without pointing a CL to it. To set this up, use the `--beacon.api` flag. Information
provided by the beacon chain is verified, i.e. geth does not blindly trust the beacon
API endpoint in this mode. The root of trust are the beacon chain 'sync committees'.
The configured beacon API endpoint must provide light client data. At this time, only
Lodestar and Nimbus provide the necessary APIs.
There is also a standalone tool, cmd/blsync, which uses the beacon chain light client
to drive any EL implementation via its engine API.

Improving two things here:
On hive, where we look at these tests, the Go code comment above the test
is not visible. When there is a failure, it's not obvious what the test is actually
expecting. I have converted the comments in to printed log messages to
explain the test more.
Second, I noticed that besu is failing some tests because it happens to request
a header when we want it to send transactions. Trying the minimal fix here to
serve the headers.
