Change the way that IO exceptions are handled and some associated details:

1. In the top-level exception handler, don't treat IO exceptions as a panic,
just print them out and stop.

2. In the slurping routines SysTools.copy and the fake cpp in
DriverPipeline, don't catch IO exceptions, just let them propagate.
