8ce4433821 Do not call setroot() from MD code and from MI code, which has 
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.

No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().

Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().

Make cpu_rootconf(9) describe the calling order.

67d81114c7 Implement dummy `cpu_mcontext_validate' to make it compile again. This 
function needs to be implemented in the target secton one day for extra
security.

8caa187077 Implement signal forwarding to userland for usermode kernels. Especially 
SIGFPE is important since the urkel shouldn't stop when a userland program
devides by zero!

1ea95bd622 Complete rewrite of the signal and spl framework for NetBSD/usermode 
Signals are now moved from the sigaltstack ASAP and stacked on a replacement
stack for each processes.

Preemption now works though could be enhanced a bit more

20157f98bc Create an atomic switchto() that has SIGALRM and SIGIO signals blocked that 
might otherwise disrupt the setting of curlwp to match the lwp context.

7752740c40 Reimplement userret() to also include AST for preemption. 
Note it would be nice if we could do the check "are we going to userland?" in
a less intrusive way.

cd980be679 Revamp the NetBSD/usermode pagefault and illegal instruction handing. It now 
can handle recursive entry and is a lot more memory tight compared to the old
implementation. Performance wise:

* slightly less number of syscalls/sec possible though could be optimized
* a lot faster context creation / destruction making overall operation faster.

453f61bbf1 sizeof_t is allways >=0 and the check for >=0 thus allways is true and amd64 
complains about this. This might explain the odd write errors that could
sometimes be reported. Those are/were probably a side effect of this.

4f5a27ac46 Replace the SDL based genfb driver with a wsdisplay and wskbd driver that 
implements the VNC (RFB) protocol.

To enable the VNC server, add 'vnc=640x480,5900' to the kernel command line
(where 640x480 is the desired fb resolution and 5900 is the TCP port).

d27fbb9f42 Improve usermode timecounter. It's unreasonable to assume that we'll get 
100 "SIGALRM" per second with an ITIMER_REAL at 100Hz on a HZ=100 host as
the timer may expire before a pending signal has been delivered.

Instead of setitimer, use timer_create + timer_settime and from our
intr handler use timer_getoverrun to determine how many ticks we have
missed.
