SELinux: export object class and permission definitions
Moves the definition of the 3 structs containing object class and permission definitions from avc.c to avc_ss.h so that the security server can access them for validation on policy load. This also adds a new struct type, defined_classes_perms_t, suitable for allowing the security server to access these data structures from the avc.
