Subject: [PATCH] miner: restore GasUsed assignment in applyTransaction

The BAL refactoring in 5808d212b removed the line that sets
header.GasUsed = gasPool.Used() after each transaction in the
miner's applyTransaction. This caused all geth-proposed blocks
to have GasUsed=0 in the header, which every other client
rejects during validation.
