Integration of many changes from Matthias Pfaller plus some of mine.
Several had: _MACHINE_ICU_H_ -> _NS32K_ICU_H_ cpu.h * Removed definition of cpu_swapout. * Added definition of cpu_wait. frame.h * added struct switchframe icu.h * tweeked ints_off param.h * More derived constants. * Alot of things taken over from i386/include/param.h. pcb.h * Removed pcb_flags (was unused) and pcb_pl. The current priority level is now stored in the switch frame by cpu_switch. pmap.h * Taken over from i386/include/pmap.h. psl.h * Add USERMODE definition trap.h * T_INTERRUPT -> T_AST types.h * Remove __FORK_BRAINDAMAGE vmparam.h * Taken over from i386/include/vmparam.h. Added definition of INTSTACK.
