c2cd510adf Removed debug dumps from the PM and FS servers. The dumps are now done by the 
IS servers, which obtains a copy of the data through the getsysinfo() system
call. CTRL-F1 now is a special TTY key to shows function key mappings.

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.

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.

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.

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.
