Audit message dictionary

Hi, I've created an audit message dictionary along the lines of the existing audit field dictionary to add to the github audit documentation repository. It is checked in to: https://github.com/linux-audit/audit-documentation/blob/master/specs/mess... related to issue: https://github.com/linux-audit/audit-documentation/issues/21 This is a preliminary commit that was created from userspace' lib/libaudit.h and kernel's include/uapi/linux/audit.h, merging, sorting and removing duplicates and verifying I've not missed anything obvious from ausearch. It might be useful to find a way to add the message range descriptions to this CSV file, or to add them to another file in the same directory. Comments, fixes and additions welcome. - RGB -- Richard Guy Briggs <rgb(a)redhat.com&gt; Sr. S/W Engineer, Kernel Security, Base Operating Systems Remote, Ottawa, Red Hat Canada IRC: rgb, SunRaycer Voice: +1.647.777.2635, Internal: (81) 32635
