Catch UTXO set read errors and shutdown #5619

1. 
   sipa commented at 1:40 pm on January 8, 2015: member

   This is a minimally invasive patch to shutdown on LevelDB read errors from the chainstate. The block index does not need similar protection, as it’s only read at startup.

   Should apply cleanly to 0.10 as well.

   You can leave out the detailed error message in the UI. Just log it to debug.log for troubleshooting.

   Message also needs a _() for translation.
