There are actually two types of error will be returned when a tranaction/message call is executed: (a) consensus error (b) evm internal error. The former should be converted to a consensus issue, e.g. The sender doesn't enough asset to purchase the gas it specifies. The latter is allowed since evm itself is a blackbox and internal error is allowed to happen. This PR emphasizes the difference by introducing a executionResult structure. The evm error is embedded inside. So if any error returned, it indicates consensus issue happens. And also this PR improve the `EstimateGas` API to return the concrete revert reason if the transaction always fails
