	src/sys/arch/sparc/sparc: cpu.c cpuvar.h intr.c trap.c

Log Message:
- add a new message tag for level15 software NMI, and switch ddb to use this
rather than the level13 software intr xpmsg area.  now DDB IPI's don't lock
the xpmsg_lock and we avoid recursion and more.
- don't actually use cpuinfo.msg.lock yet, xpmsg_lock suffices.
- reread the pending register on mbus hypersparc cpus to avoid bugs in the
h/w that cause IPI's to be missed.
