[Piglit] [RFC 1/9] util: Add a function for enumerating subtests

[Dylan Baker]

I meant to add a cover letter to this, also, there's only 8 patches.

This is an RFC, I'm looking for input into fixing the subtest reporting problem.
This approach is going to be more complete, but it's going to be pretty
involved. If anyone has a better approach I'd be happy to hear it.
