d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

ed9f910cc8 Introduce WSDISPLAY_NULLSCREEN to allow low level device to detach control
process. Hpcmips frame buffer driver(hpcfb) call wsdisplay_switch with
WSDISPLAY_NULLSCREEN to notify user process of suspend/resume event.

665eca96e0 In wsdisplay_usl_ioctl2(), use a u_long for the request to be passed off
to wsdisplay_internal_ioctl() instead of an int.
With this, the pcvt compat ioctl's work on an Alpha and probably other
64 bit archs.

fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

8996199a85 -allow the "show_screen" call to the display driver to complete
asynchronously, in the same style like the process attach/detach functions
-intercept the "cnpollc" call which originally went directly to the
 keyboard driver and keep track whether the console is in "polling" state
 (DDB!)
-pass a NULL callback to the screen switcher and the process attach/detach
 functions if the console is "polling", to tell them that asynchronous
 completion is forbidden

02bd5fa80e Split wsdisplay_usl_ioctl() into two functions -- one which is screen-dependent
and one which isn't.  The latter is now used for ttyEcfg, enabling the
VT-switching ioctls to work on it.  (This allows Linux X servers to work when
/emul/linux/dev/tty0 is linked to /dev/ttyEcfg.)

309847b355 improve error handling in 2 cases:
1. If the current screen becomes invalid (ie no focus anymore), always
   set the keyboard to translating mode. Otherwise, we could get stuck
   because the command keystokes don't come through.
2. Catch errors in attaching to a process (X server) - For this,
   implement a callback mechanism similar to the detach case. Add an
   argument to report an errno via callback.
