reduce chain database size

[gzliudan]

Now the receipt RLP format in our chain database is:

type receiptStorageRLP struct {
	PostStateOrStatus []byte
	CumulativeGasUsed uint64
	Bloom             Bloom
	TxHash            common.Hash
	ContractAddress   common.Address
	Logs              []*LogForStorage
	GasUsed           uint64
}

In fact the below fields are unnecessary in database:

• Bloom
• TxHash
• ContractAddress
• GasUsed

because they can be derive from the transaction. Then format can be simplified to:

type storedReceiptRLP struct {
	PostStateOrStatus []byte
	CumulativeGasUsed uint64
	Logs              []*Log
}

So we can encode the new receipt RLP with the new format. Then convert the old receipt RLP to the new format later.
