1. bus-mapping: Extend CircuitInputBuilder …

   - CircuitInputBuilder:
       - Fix `gen_state_access_trace` by splitting the code and address in the
         context of a call.
       - Add `codes` field in the CircuitInputBuilder to keep a mapping of
         code hash -> code.
       - When doing the `gen_associated_ops` step for opcodes not yet
         implemented, instead of panic show a log warning, so that we can
         generate circuit inputs for blocks eventhough the implementation
         is not complete.  This will allow performing integration tests.
       - Resolve #207
   - rpc:
       - Add `eth_coinbase` and `eth_chainId` methods.
       - Remove `BlockNumber` in favour of the implementation in `ethers`.
   - General:
       - Replace usage of `BlockConstants` by the new struct
         `ChainConstants`.  This way we split constant parameters of the
         chain into `ChainConstants` and block parameters into `Block`.
         `BlockConstants` is now only used by the external_tracer.
       - Move `BlockConstants` from `bus-mapping/src/exec_trace.rs` to
         `bus-mapping/src/external_tracer.rs`.
       - Implement the Debug trait for some types manually to make debug
         output nicer.
       - Introduce a `circuit_input_builder` integration test with geth.
         The test builds the circuit inputs for the block where the
         Greeter.sol contract is deployed, up to step 5 from
         #222 (whith
         some missing parts)
       - Fix `mload` by allowing memory reads at addresses higher than the
         memory size found in the trace (in such case, a 0 value is read)
