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

done only if PMAP_DEBUG is defined). Other minor clean-up...

Also add the function trap_kdebug() which takes care of calling one of:
kgdb_trap (for KGDB), or kdb_trap, (for DDB) or the Sun PROM monitor.
This logic used to be in locore, but it is better as C code.
