Retrieve the Coin (unspent transaction output) for a given outpoint.
Returns true only when an unspent coin was found, which is returned in coin. When false is returned, coin's value is unspecified.

Retrieve the range of blocks that may have been only partially written.
If the database is in a consistent state, the result is the empty vector. Otherwise, a two-element vector is returned consisting of the new and the old block hash, in that order.
