Keep track of traced child under a list of orphans while they are being
reparented to a debugger process.
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@.
While here rename proc_reparent() into process_reparent() and get rid of
superfluous checks.
