I knew that more keys can be added with the 0x01 separator. However, this patch
supports different types of keys and plugins could recognize audit
events using them.

For example, I'm working on reactive audit and I need to separate normal audit
events from those generated by reactive rules and find out which
reaction(s) should
be triggered. -F react=reaction can be added to the audit (AUDIT_REACTKEY) and
audit events would include reaction identifiers such as react="reaction"

Also, I know about "ids-..." key and I could use something like
"react-...", but the
plugin would have to go through all the key="..." and compare, which
of them have
"react-" at the beginning.
