Lets add a function to get stamps for our reports. It'll help with
finding the test case that was causing problems in dumps.

I know this should be a common discussion and it will be later. But
first I want to get a few opinions here, especially about how to wire
that up. Using ifdefs? Enabling via argv?
My current plan for s390 is to register a wrapper of time_get_ns()
that prints "[%ld]" as the stamp prefix. As other archs might have
other values or might want to include the cpu# I kept it as generic as
possible.
