LSM: shrink the common_audit_data data union
After shrinking the common_audit_data stack usage for private LSM data I'm not going to shrink the data union. To do this I'm going to move anything larger than 2 void * ptrs to it's own structure and require it to be declared separately on the calling stack. Thus hot paths which don't need more than a couple pointer don't have to declare space to hold large unneeded structures. I could get this down to one void * by dealing with the key struct and the struct path. We'll see if that is helpful after taking care of networking.
