eth/tracers: live chain tracing with hooks #29189 (#1352)
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.

eth/tracers, core/vm: remove time from trace output and tracing interface #26291 (#1311)
This removes the 'time' field from logs, as well as from the tracer interface. This change makes the trace output deterministic.  If a tracer needs the time they can measure it themselves. No need for evm to do this.
