inheritance/permission.
* spawn.cc (spawn_guts): Ditto.
* security.cc (create_token): Initialize token so that it is not tested for
bogus value later.  Use sec_user to control process/thread creation.
* security.h (__sec_user): Rename declaration from sec_user.
(sec_user_nih): Declare here as inline function wrapper for __sec_user.
(sec_user): Ditto.
* sigproc.cc (czombies): Allocate a character array for zombies to avoid
constructor overhead
(extremely hackish, I know).
(cpchildren): Ditto.
(pchildren): New define.
(zombies): Ditto.
(getsem): Use sec_user_nih to control semaphore inheritance/permission.
