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.

eth/tracers: live chain tracing with hooks (#29189 )

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.

cmd/evm: calc base fee if parent data is present (#26051 )

Currently, in order to chain together sequential valid t8n transitions the caller must manually calculate the block base fee. This PR adds support for the necessary parent fee market data to calculate the base fee for the current transition.

Concretely, env is extended to accept the following:

    parentBaseFee
    parentGasUsed
    parentGasLimit

Example usage can be found in ./cmd/evm/testdata/25.
