TOMOYO: Add interactive enforcing mode.
Since the behavior of the system is restricted by policy, we may need to update policy when you update packages. We need to update policy in the following cases. * The pathname of files has changed. * The dependency of files has changed. * The access permissions required has increased. The ideal way to update policy is to rebuild from the scratch using learning mode. But it is not desirable to change from enforcing mode to other mode if the system has once entered in production state. Suppose MAC could support per-application enforcing mode, the MAC becomes useless if an application that is not running in enforcing mode was cracked. For example, the whole system becomes vulnerable if only HTTP server application is running in learning mode to rebuild policy for the application. So, in TOMOYO Linux, updating policy is done while the system is running in enforcing mode. This patch implements "interactive enforcing mode" which allows administrators to judge whether to accept policy violation in enforcing mode or not.
