* 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: 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
* core/vm: use fixed uint256 library instead of big
* core/vm: remove intpools
* core/vm: upgrade uint256, fixes uint256.NewFromBig
* core/vm: use uint256.Int by value in Stack
* core/vm: upgrade uint256 to v1.0.0
* core/vm: don't preallocate space for 1024 stack items (only 16)

This PR adds a new fork which disables EIP-1283. Internally it's called Petersburg,
but the genesis/config field is ConstantinopleFix.
The block numbers are:
7280000 for Constantinople on Mainnet
7280000 for ConstantinopleFix on Mainnet
4939394 for ConstantinopleFix on Ropsten
9999999 for ConstantinopleFix on Rinkeby (real number decided later)
This PR also defaults to using the same ConstantinopleFix number as whatever
Constantinople is set to. That is, it will default to mainnet behaviour if ConstantinopleFix
is not set.This means that for private networks which have already transitioned
to Constantinople, this PR will break the network unless ConstantinopleFix is
explicitly set!
