Renamed SYS_SETPRIORITY to SYS_NICE.

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.

2abe246e5c (Im)port of zlib-1.2.2 
Ran configure with minix-friendly args and committed makefile. It's
a compromise to make zlib fit nicely into the current build system.

ec24a0798c Updated function key mapping because of possible changes to NOTIFY. 
The TTY driver now only notifies the IS server about function key event,
but does not tell which keys are pressed. The IS servers queries the TTY
driver to find out about this.

39c90d6c90 Added (fake) readlink().

2f74381dcc Fixed 'ps' utility: now get process table addresses with getsysinfo() calls. 
To be done: get copies of process tables instead of using /dev/(k)mem.

e44e9ad261 small compile fixes; initial select() stubs; release.sh script doesn't 
need /tmp any more since 16MB root device; increase to 3.0.5 to make new
CD with working FXP driver. (not tagged 3.0.5 yet as at driver bios-copy
workaround hasn't been done.)

f2a85e58d9 Various updates. 
* Removed some variants of the SYS_GETINFO calls from the kernel;
  replaced them with new PM and utils libary functionality. Fixed
  bugs in utils library that used old get_kenv() variant.
* Implemented a buffer in the kernel to gather random data.
  Memory driver periodically checks this for /dev/random.
  A better random algorithm can now be implemented in the driver.
  Removed SYS_RANDOM; the SYS_GETINFO call is used instead.
* Remove SYS_KMALLOC from the kernel. Memory allocation can now
  be done at the process manager with new 'other' library functions.

e782e76944 Created new findproc system call to the PM (to replace similar kernel 
functionality). Currently working on memory allocation (not yet finished).

6d23f072f3 Cleaned up src/lib/utils library. Renamed server_ functions to more logical 
names. All system processes can now either use panic() or report() from
libutils, or redefine their own function. Assertions are done via the standard
<assert.h> functionality.

b4335679cb Added sys_physzero library call for corresponding system call; modified

smart formatting)

0165662cd9 Replaced flagalrm() timers with another technique to check for timeouts. 
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.

322ec9ef8b Moved stime, time, times POSIX calls from FS to PM. Removed child time 
accounting from kernel (now in PM).  Large amount of files in this commit
is due to system time problems during development.

307c825515 New NOTIFY trap (IPC call) to send queued notification messages. 
The call works. Permission check, restriction of outstanding notifications
to be added. Low level code to make it work from within interrupt handlers
will be added as well.
