        src/sys/arch/sparc/sparc: timer.c timer_sun4m.c timervar.h

Log Message:
remove schedintr_4m(), and go back to only having the level 14
timer call statclock/schedclock.  the randomness for this clock
makes the hardclock() call very jittery.

instead of this, trigger a softintr IPI at level 10 on non-primary
CPUs from the primary CPU's clock interrupt (at level 10.)  this
cleans up the generic sparc timer code a little as well.

this makes the time goes backwards problem *much* less frequent,
but i still see it sometimes.
