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.

Looks good:

A couple nits below:

+# Standard cleanup function.  Individual tests should override this.
+_cleanup()
+{
+	cd /
+	rm -r -f $tmp.*
+}

It should say "can override this", not "should override this".

+# Initialize the global seq, seqres, here, tmp, and status variables to their
+# defaults.  Group memberships are the only arguments to this helper.
+_begin_fstest()
+{

This function does more than what the comment says.  It should say something
more along the lines of "Prepare for executing a fstest by initializing some
global variables, registering a default cleanup function, importing helper
functions, and removing $seqres.full.  This must be passed the list of groups to
which the test belongs."
