Ian Wienand 7550d25db0 Export die() function
I realised I'd been using die() in a few places assuming it was
available, but it wasn't exported.  I guess it didn't matter because
whatever was wrong, we were failing anyway :)

This exports the function to make it available to sub-processes, which
should remove the need to source it as done in several places.
