[PATCH v2 0/7] nfs-utils: nfsconf cli tool and code tests

[Justin Mitchell <jumitche@redhat.com>]

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
