This is a minimally invasive approach to shutdown on LevelDB read errors from the chainstate, while keeping user interface out of the common library, which is shared between bitcoind, and bitcoin-qt and non-server tools.
Writes do not need similar protection, as failure to write is handled by the caller.

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.
Reimplemented from CCoinsViewBacked.
