9986e07e1f Remove the code that renices +4 a process that has had 10 minutes of 
CPU time. I find it slightly annoying on one of our servers here.

4f898e1524 Changed wakeup_one() to continue looping, possibly waking up additional 
processes, until it finds one that is not swapped out.

b1508c72f4 Converted timer/run queues to 4.4BSD queue style. Removed old and unused 
sleep(). Implemented wakeup_one() which may be used in the future to combat
the "thundering herd" problem for some special cases.

729b1e5149 Improved killproc() log message and made it and the other similar message 
tolerant of p_ucred being invalid. Starting using killproc() where
appropriate.

Submitted by:	terry (terry lambert)
This is  a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.

b5e8ce9f12 Add and move declarations to fix all of the warnings from `gcc -Wimplicit' 
(except in netccitt, netiso and netns) and most of the warnings from
`gcc -Wnested-externs'.  Fix all the bugs found.  There were no serious
ones.

7216391e49 "idle priority" support. Based on code from Henrik Vestergaard Draboel, 
but substantially rewritten by me.

bb56ec4a05 While in the real world, I had a bad case of being swapped out for a lot of 
cycles.  While waiting there I added a lot of the extra ()'s I have, (I have
never used LISP to any extent).  So I compiled the kernel with -Wall and
shut up a lot of "suggest you add ()'s", removed a bunch of unused var's
and added a couple of declarations here and there.  Having a lap-top is
highly recommended.  My kernel still runs, yell at me if you kernel breaks.
