Move spl macros from <machine/param.h> to <machine/intr.h>
Fix botch on my part and make the IPL_* match reality on VAX. Redefine spl macro using the symbolic IPL_ instead of being hardcoded. Move schedsoftnet, schedsoftclock from <machine/cpu.h> to <machine/intr.h> Add a _setsirr macro for schedsoft*. Add softintr function and framework.
