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. More...

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.
