308d9a693c prettified rtl driver:
. no more kmalloc
 . no more umaps + physcopies / abscopies
 . the status register is directly readable from the drivers own
   address space now, and no physcopy is needed to read it
 . map+physcopy call combinations are replaced by vircopy calls

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.

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.

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.

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...)

Furthermore, a quick way to get one's own process number.

c2be104821 Improved NOTIFY system: fixed a minor error, ignore pending notifications
on SENDREC system calls. To be done: resource (buffer pool) management;
make it structurally impossible to run out of buffers.

77c3213948 Optimized scheduling code. Old code is still available withing DEAD_CODE
and NEW_SCHED_Q definitions. Some minor problems are being traced at the
moment. This commit is meant to backup my files.

ccd17ecfed New NOTIFY system call! Queued at kernel. Duplicate messages (with same source
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.
