This commit converts all block height references to int32 instead of int64. The current target block production rate is 10 mins per block which means it will take roughly 40,800 years to reach the maximum height an int32 affords. Even if the target rate were lowered to one block per minute, it would still take roughly another 4,080 years to reach the maximum. In the mean time, there is no reason to use a larger type which results in higher memory and disk space usage. However, for now, in order to avoid having to reserialize a bunch of database information, the heights are still serialized to the database as 8-byte uint64s. This is being mainly being done in preparation for further upcoming infrastructure changes which will use the smaller and more efficient 4-byte serialization in the database as well. |

Package database provides a database interface for the bitcoin block chain and transactions.
Please note that this package is intended to enable btcd to support different database backends and is not something that a client can directly access as only one entity can have the database open at a time (for most database backends), and that entity will be btcd.
When a client wants programmatic access to the data provided by btcd, they'll likely want to use the btcrpcclient package which makes use of the [JSON-RPC API] (https://github.com/btcsuite/btcd/tree/master/docs/json_rpc_api.md).
