2bf8bfe126 Turn IPC warning messages off by default 
(because inet deadlocks are normal and will confuse our users).

ea75918df1 printf() by kernel and servers now send messages to an array of processes, 
OUTPUT_PROCS_ARRAY in <minix/config.h>, in that order, terminated by NONE.
log no longer forwards messages to tty itself. This leads to less funny
loops and more robust debug-message handling. Also the list of
processes receiving messages can easily be changed around or disabled by
editing the array (e.g. disable it by changing the array to { NONE }.).

c655d8b3ae Added shutdown_started global variable. If it's set, we're in the 
process of doing a shutdown.

Initial purpose is - suppress dead process diagnostic message.

b4d7de6ee1 New makefile (src/tools/Makefile) logic: 
- make fresh install: still builds new everything (libraries, services, image)
- make clean image: only builds new boot image (about 5 sec. now!)

872687ddfc Scheduling updates to the kernel. Sched() function now is single point for 
policy. Actual policy not yet implemented.

PM calculates nice values for processes in boot image.

IS debug dumps improved (Shift+F1-F4).

bfb7608412 various small fixes. 
. motd update (ast)
 . made /usr/local/man/man* and made them bin-owned (mtree)
   (to let bin install there)
 . made copyright notice in kernel 1987-2006 (ast)
 . added chown -R bin /usr/src so that bin can compile everything

b293e689a9 . Allow drivers to to physcopy() (table.c) 
. Also allow receive() to be done from kernel processes, not just
  sendrec(). This is because receive()s can't harm the kernel processes,
  but are done from the CLOCK task (without sendrec()).
