Log Message:
Move fork_kthread() to a new file, kern_kthread.c, and rename it to
kthread_create().  Implement kthread_exit() (causes a thrad to exit).
Set P_NOCLDWAIT on kernel threads, which will cause any of their children
to be reparented to init(8) (which is already prepared to wait out orphaned
processes).
