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.
