Log Message:
Initial version of API for creating kernel threads (likely to change somewhat
in the future):
- New function, fork_kthread(), takes entry point, argument for entry point,
and comment for new proc.  May be called by any context, will fork the
thread from proc0 (requires slight changes to cpu_fork()).
- cpu_set_kpc() now takes a third argument, a void *arg to pass to the
thread entry point.  Thread entry point now takes void * instead of
struct proc *.
- Create the pagedaemon and reaper kernel threads using fork_kthread().
