* consensus/ethash: start remote ggoroutine to handle remote mining * consensus/ethash: expose remote miner api * consensus/ethash: expose submitHashrate api * miner, ethash: push empty block to sealer without waiting execution * consensus, internal: add getHashrate API for ethash * consensus: add three method for consensus interface * miner: expose consensus engine running status to miner * eth, miner: specify etherbase when miner created * miner: commit new work when consensus engine is started * consensus, miner: fix some logics * all: delete useless interfaces * consensus: polish a bit
