* core/vm: reverse bit order in bytes of code bitmap
This bit order is more natural for bit manipulation operations and we
can eliminate some small number of CPU instructions.
* core/vm: drop lookup table
* core/vm: Remove interpreter loop interruption check
* core/vm: Unit test for interpreter loop interruption
* core/vm: Check for interpreter loop abort on every jump
* core/vm: Move interpreter.ReadOnly check into the opcode implementations
Also remove the same check from the interpreter inner loop.
* core/vm: Remove obsolete operation.writes flag
* core/vm: Capture fault states in logger

* core/vm: Remove panic added for testing

* core/vm: break loop on any error
* core/vm: move ErrExecutionReverted to opRevert()
* core/vm: use "stop token" to stop the loop
* core/vm: unconditionally pc++ in the loop
* core/vm: set return data in instruction impls
* all: mv loggers to eth/tracers
* core/vm: minor
* eth/tracers: tmp comment out testStoreCapture
* eth/tracers: uncomment and fix logger test
* eth/tracers: simplify test
* core/vm: re-add license
* core/vm: minor
* rename LogConfig to Config
This change introduces 2 new optional methods; `enter()` and `exit()` for js tracers, and makes `step()` optiona. The two new methods are invoked when entering and exiting a call frame (but not invoked for the outermost scope, which has it's own methods). Currently these are the data fields passed to each of them:
enter: type (opcode), from, to, input, gas, value
exit: output, gasUsed, error
The PR also comes with a re-write of the callTracer. As a backup we keep the previous tracing script under the name `callTracerLegacy`. Behaviour of both tracers are equivalent for the most part, although there are some small differences (improvements), where the new tracer is more correct / has more information.
* internal/ethapi: revert + fix properly in al tracer
* internal/ethapi: use toMessage instead of creating new message
* internal/ethapi: remove ineffassign
* core: fix invalid unmarshalling, fix test

This is the initial implementation of EIP-1559 in packages core/types and core.
Mining, RPC, etc. will be added in subsequent commits.

Previously, the makeCallVariantGasCallEIP2929 charged the cold account access cost directly, leading to an incorrect gas cost passed to the tracer from the main execution loop.
This change still temporarily charges the cost (to allow for an accurate calculation of the available gas for the call), but then afterwards refunds it and instead returns the correct total gas cost to be then properly charged in the main loop.

Fixes the CaptureStart api to include the EVM, thus being able to set the statedb early on. This pr also exposes the struct we used internally in the interpreter to encapsulate the contract, mem, stack, rstack, so we pass it as a single struct to the tracer, and removes the error returns on the capture methods.
