Implement pmap_pa_exists() so that /dev/mem works.
...
This was the reason ps (kvm_getargs) did not work.

Physical page status functions pmap_clear_reference()
...
and pmap_clear_modify() weren't testing if the page whose status was being
changed was being managed. This caused kernel panics with X11.

Add pmap_bootstrap_setprom() with sets the PROM level-A tables to
...
allow the PROM monitor to see mappings in kernel space. This also
fixes a problem with exiting to the monitor with the stack pointer
set to some place in kernel space. Also fix NUM_KERN_PTES, and
change get_pte() so it works on any virtual address.

Fix a major bug in pmap_remove_kernel() that causd the removal of
...
one page too many (worse, it unmapped our stack page... Ouch!)
Also, use loadcrp() and such instead of calling pmap_activate
in various places so we have more control over TLB flush.
Now pmap_activate() is called only by locore (and that call is
done only if PMAP_DEBUG is defined). Other minor clean-up...
