42050e39f8 kernel and servers send diagnostic messages to IS; IS sends them to TTY 
and the new log driver if enabled.

new usyslogd is started from /usr/etc/rc. New device created by
MAKEDEV.sh. /var/log created by etc/mtree/minix.tree (on root for
now). Made select() slightly more generic, with less code duplication.

640eb73ca2 New log driver; buffers messages and makes them available to userland. 
Added some fields in the generic device table to support this driver
using libdriver. Updated other drivers to fill these fields with nops
and NULLs.

c021dafe27 usyslogd - microsyslogd that has a hard-coded configuration (read from 
/dev/klog and write to /var/log/messages). It's written so that more
sources and outputs could be added easily though.

made FD_SETSIZE pre-#include-definable, with OPEN_MAX as default if unset.

904cf1f84d A "fix" for bug no. 2 is to check if the process slot has disappeared. 
Not a really good solution (as it might not catch situations in which this
is caused by another bug), but the forrest of checks necessary might be worse
than this quick fix - because when looking for the cause, I found some other
cases in which the PM would panic as well. See info in bug 2 for details.

Another fix is to delay notification of PM by SYSTASK of signals delivered
internally until after the reply (e.g. of exec()), because the reply would
be messed up otherwise (receiving the notify instead of reply). This caused
SIGTRAP not to be delivered properly with traced processes.

5939b6a4d7 . fsck has A for yes-to-all response 
. mkfs makes filesystems on devices >4GB, but truncates them at 4GB

2ce80ece5c Fix to check for RDTSC instruction (above 486), and call another timing 
function instead if RDTSC is unavailable. This makes minix run on 486
again :) (presumably lower as well).

ebd38d9a92 Added formatting fixes for larger numbers in fsck and df; made mkfs 
test for devices larger than 4GB, so it won't try to test them (and print
a warning message), but it will write the FS.
