[PATCH] - auditing cmdline

This patch series relates to work started on the audit mailing list. It eventually involved touching other modules, so I am trying to pull in those owners as well. In a nutshell I add new utility functions for accessing a processes cmdline value as displayed in proc/<self>/cmdline, and then refactor procfs to use the utility functions, and then add the ability to the audit subsystem to record this value. Thanks for any feedback and help.
