Log Message:
MD component of the new cpu_switch() interface.  Introduces nextrunqueue(),
cpu_idle() and new cpu_switch() to replace the old cpu_switch()
which did the lot.  Runs leaner without overly blocking interrupts.

Includes cleanup of the RAS code to make use of callee-saved registers.

Benchmarks on DX4 @ 100MHz reveal a slight performance improvement
but probably not statistically signficant.  More TBD to verify this.

Changes passed a pounding on Athlon @ 1GHz too.
