[Pmk-devel] pmksetup fix

[Damien C. <mip...@us...>]

Hi all !

Due to lack of testers the 0.9.1 release has been provided with two 
bugs. The first is that using pmksetup with -v argument is flushing the 
configuration file content. The second is leaving the temporary file of 
pmksetup if ran without correct privileges.

The attached diff is splitting the arguments parsing in two parts : the 
first part is now in main() and process -v and -V flags that are safe 
while in privileged mode. The other allowed arguments are parsed in the 
child (non privileged) part to reduce risks.

The result is that -v is exiting really early now. The renaming/saving
part of the configuration file is now done only if child status is okay.

Another change is that the temporary file is also written in the same 
directory than the configuration file. This directory is also checked 
and created earlier than before to avoid running tests if the results 
cannot be written.

If you have some time to review and test this diff i'd be happy to get 
some feedback to quickly release a bugfix release.

Cheers,
Damien
