From: Darrick J. Wong <djwong@xxxxxxxxxx>
Create two new helper functions to deal with boilerplate test code:
A helper function to set the seq and seqnum variables. We will expand
on this in the next patch so that fstests can autogenerate group files
from now on.
A helper function to register cleanup code that will run if the test
exits or trips over a standard range of signals.
