Added an IDENTIFIED flag that is set on successfully identified drives.
...
This avoids the bug scenario where DEAF but not-w_identify()d drives are
never properly identified, but are seen as real devices.

Small update to shared driver code: SYS_EVENT (signal) is now known.
...
Fixed drivers. HARD_STOP message no longer exists.

Changed Makefiles: drivers are now installed in /usr/sbin.
...
TTY now gets SYS_EVENT message with sigset (e.g., SIGKMESS, SIGKSTOP).

Made timeout and no. of errors in at_wini dynamically settable
...
by ioctl; made catch-all function in driver table also called when
unrecognized ioctl called, so drivers can add their own ioctl codes.

New log driver; buffers messages and makes them available to userland.
...
Added some fields in the generic device table to support this driver
using libdriver. Updated other drivers to fill these fields with nops
and NULLs.

...
Timeouts are sent by the CLOCK.

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.

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.

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.
