There exist open/closed buckets and closed tx buckets for all types (open txs are in volatile storage).

Needed by miner and p2p package.

Get all pubKey involved in AccTx.

Get all pubKey involved in FundsTx.

Get all pubKeys involved in AccTx, FundsTx of a given block.

Entry function for the storage package.

Needed for the miner to prepare a new block.

Personally I like it better to test (which tx type it is) here, and get returned the interface.

Always return nil if requested hash is not in the storage.

Changing the "tx" shortcut here and using "transaction" to distinguish between bolt's transactions.
