newest version..
this version has been tested somewhat, and adds a new function.
the new function, when given a pointer to a pointer to a proc, will
make a new kproc when the proc * is NULL (i.e. the first time it is called)
and fill it in, and therafter, add new kthreads to that process.
it has a rather clumsy name of kproc_kthread_create, so if you don't
like it sugeest something better.. it uses kproc_create and kthread_create.
after applying this patch top -SH shows the following:

other current kprocs can be turned into kthreads with minimal
(usually a few seconds) edits
note kthread_create() has grown an extra argument, a struct proc *
that is used to tell it which kproc to add the thread to.
comments?
code-reviews?
ps -auxH -Otdnam gives output different from what I'd expect
and strange messages appear on the console. so comments on that
(the ps diffs) are definitly requested.
