[PATCH v3 0/8] nfs-utils: nfsconf cli tool and code tests

[Justin Mitchell <jumitche@redhat.com>]

Apologies for the noise, I missed some files out when I last
reposted, so here is an updated and tested version.

v3
Include files that were missed out of v2
Add the man page for nfsconftool

v2
Updated style and commenting to make the code clearer

v1
This series introduces a new cli tool to nfs-utils which provides
for the dumping of the current configuration, querying of individual
settings in a scripting friendly manner and by extention the 
scripted testing and verification of nfsconf functionality.

The previously unreferenced conf_report() is modified to produce
a sorted output, which allows you to --dump the current config in
a way thats easier to diff

As well as some improved error messages a script is included which
tests the current config parsing code by supplying various example
config files and comparing the results of the --dump output.

The cli tool also allows a simple test to check if a config item
has been set, and to retrieve the current value in a way that is
easy to call from a shell script.

As the next stage I hope to impliment config setting via the cli 
tool in order to provide an api for automation and management tools
