LSM/Audit: Introduce generic Audit LSM hooks
Introduce a generic Audit interface for security modules
by adding the following new LSM hooks:
audit_rule_init(field, op, rulestr, lsmrule)
audit_rule_known(krule)
audit_rule_match(secid, field, op, rule, actx)
audit_rule_free(rule)
Those hooks are only available if CONFIG_AUDIT is enabled.
