Adding a key to syscall rules

[Steve Grubb]

Hello,

I wanted to bring something up. Currently, we have the ability to add a custom 
"tag" or key to filesystem auditing rules. I got to thinking that this should 
also be done for syscall auditing. This way, admins can set a rule with a 
custom key and search for it later. (I have to write the search code.) 
Besides being useful, I think this should be done for symmetry between 
syscall & filesystem auditing as well.
