Nick Johnson	781915f183	core/vm: Refactor tracing to make Tracer the main interface This CL makes several refactors: - Define a Tracer interface, implementing the `CaptureState` method - Add the VM environment as the first argument of `Tracer.CaptureState` - Rename existing functionality `StructLogger` an make it an implementation of `Tracer` - Delete `StructLogCollector` and make `StructLogger` collect the logs directly - Change all callers to use the new `StructLogger` where necessary and extract logs from that. - Deletes the apparently obsolete and likely nonfunctional 'TraceCall' from the eth API. Callers that only wish accumulated logs can use the `StructLogger` implementation straightforwardly. Callers that wish to efficiently capture VM traces and operate on them without excessive copying can now implement the `Tracer` interface to receive VM state at each step and do with it as they wish. This CL also removes the accumulation of logs from the vm.Environment; this was necessary as part of the refactor, but also simplifies it by removing a responsibility that doesn't directly belong to the Environment.	8 years ago

core/vm: Refactor tracing to make Tracer the main interface

This CL makes several refactors:
 - Define a Tracer interface, implementing the `CaptureState` method
 - Add the VM environment as the first argument of
   `Tracer.CaptureState`
 - Rename existing functionality `StructLogger` an make it an
   implementation of `Tracer`
 - Delete `StructLogCollector` and make `StructLogger` collect the logs
   directly
 - Change all callers to use the new `StructLogger` where necessary and
   extract logs from that.
 - Deletes the apparently obsolete and likely nonfunctional 'TraceCall'
   from the eth API.

Callers that only wish accumulated logs can use the `StructLogger`
implementation straightforwardly. Callers that wish to efficiently
capture VM traces and operate on them without excessive copying can now
implement the `Tracer` interface to receive VM state at each step and
do with it as they wish.

This CL also removes the accumulation of logs from the vm.Environment;
this was necessary as part of the refactor, but also simplifies it by
removing a responsibility that doesn't directly belong to the
Environment.

core: added basic chain configuration

Added chain configuration options and write out during genesis database
insertion. If no "config" was found, nothing is written to the database.

Configurations are written on a per genesis base. This means
that any chain (which is identified by it's genesis hash) can have their
own chain settings.

core: Added EVM configuration options

The EVM is now initialised with an additional configured object that
allows you to turn on debugging options.
