Also re-parent exiting traced processes to their original parent, if it is still alive, after the debugger has seen the exit status. Logic comes from FreeBSD pointed out by guenther@.

Manipulate process relation/state or send a signal - kernel-state get/set: thread list, event mask, trace state. About the process and don't require target to be stopped, need copyin/out - user-state get/set: memory, register, window cookie. Often thread-specific, require target to be stopped, need copyin/out sys_ptrace() changes to handle request checking, copyin/out to kernel buffers with size check and zeroing, and dispatching to the routines above for the real work. This simplfies the permission checks and copyin/out handling and will simplify lock handling in the future.
