Re: [PATCH]: 2nd revision of make xfrm_audit_log more generic

This is 2nd revision of patch to modify xfrm_audit_log() such
that it can accomodate auditing other ipsec events
besides add/delete of an SA or SPD entry.
2nd revision includes new define for all IPsec
events in audit.h and introduces "op=" entry
in logfile as well as add a hyphen in description
for report parsing.
This is a small change to accomodate updating
ipsec protocol to RFCs 4301, 4302 and 4303 which
require auditing some ipsec events if auditing
is available. Please let me know if ok.

I like very much how the implementation of xfrm_audit_log() got
simplified.
But _TEN_ function call arguments, good grief!
That's at least twice as many as most cpus can pass in registers.
Let's try an alternative where you have specialized
xfrm_audit_log_foo() routines that take a user policy pointer, or
whatever the main object is.
If internally this just unpacks the needed bits and calls some
do_xfrm_audit_log() thing inside of the auditing code that takes lots
of arguments, that's fine, but let's not expand all of that argument
setup code in the main IPSEC code paths.
