The correct name for this field is 'input' according to the Ethereum specs [0].
However, for the longest time, clients have been using 'data' and servers have been
lenient to accept both, preferring 'input' over 'data' when both appear.
Our lack of support for 'input' had gone unnoticed until go-ethereum decided
to adjust their ethclient implementation to issue eth_call and eth_estimateGas
requests with the 'input' field instead of 'data' [1]. This suddenly broke apps
using this client against Lotus' Eth API.
