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).

89cf745fe2 Single boot driver loaded, while multiple can be included in the boot image.
The user needs to set label=... to choose the driver of his or her choice.
This driver will be mapped onto the controller that is set in controller=...

Minor cleanup of kernel source code (boot image table now is static).

b69ca94efb Fixed 'bug' in log driver that caused kernel messages not to be displayed.
This was caused by a change in the shared driver code. Not log's fault.

Renamed #definitions of driver process numbers, e.g., TTY now is TTY_PROC_NR.
All known (special) processes now have consistent naming scheme. Kernel tasks
don't follow this scheme.

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.

45ddea1cdd Fixed bug that caused the PM to brutalize the contents of the 'memory'
variable. Parsing worked, but future requests for the variable (such as
by the sysenv command) returned truncated data. This caused the system
(e.g. setup script) to think the amount of memory was tiny, and caused
the enabling of swapspace, while it is unnecessary.

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.

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.

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.

07d582872f Fixed a bug in PM: sending of reply messages didn't check if destination
process is still alive. This caused a panic in some situations, e.g., when
all processes are killed on a shutdown.
