selinux: introduce permissive types
Introduce the concept of a permissive type. A new ebitmap is introduced to the policy database which indicates if a given type has the permissive bit set or not. This bit is tested for the scontext of any denial. The bit is meaningless on types which only appear as the target of a decision and never the source. A domain running with a permissive type will be allowed to perform any action similarly to when the system is globally set permissive.
