[PATCH 0/2] nfs-utils: add testing infrastructure to nfs-utils

[Jeff Layton <jlayton@redhat.com>]

This patchset is intended as a starting point for an automated test
suite for nfs-utils. The idea here is to start simply and add a suite of
tests that we can run via "make check" -- the standard automake method
for running tests.

Clearly there are limits to what we can test with out a multi-host test
harness, but my hope is that this should keep us from breaking basic
functionality by allowing us to test it in a very simple fashion. At
some point in the future we should also consider how to best handle
multi-machine testing, but I see that as complimenting this code rather
than replacing it.

For this set, the focus is on testing statd, which is particularly
susceptible to subtle breakage. Problems with it are often not noticed
until lock recovery breaks, and that may greatly lag the actual
breakage.

To faciitate statd testing, I've added a "statdtest" program that can
serve as a synthetic statd client and an NLM simulator. It's very
loosely based on the old statd simulator code. That program is dependent
on some of Chuck's recent statd patches -- notably the ones that break
out common NSM code into libnsm.a.

For this initial drop, I'm just adding a single test that tests
mon and unmon functionality with statd. Adding more tests shouldn't be
too hard, however.

At this point, I'm mostly interested in general feedback on the concept.
Does this seem like a reasonable starting point for automated nfs-utils
