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.

5a43b84e2d Fix for 'the kermit problem' (keyrepeats happening before the keyrepeat
timeout). A fix is to treat the alarm and interrupt cases differently and
only call the interrupt handler when an actual interrupt has been seen. No
apparent adverse effects.

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.

cd72f80639 Disabled clearing screen in tty driver, started console printing after an
initial 1-line scroll at last line. If clearing screen in trailer of boot
monitor is disabled, all previous boot monitor and console messages are
preserved on rebooting.

All that's needed now is a scrollback buffer to see all old messages..
(Even from the boot monitor, bios, previous boots...)

c2be104821 Improved NOTIFY system: fixed a minor error, ignore pending notifications
