Log Message:
Several changes, which get us generally further along with
multiprocessor support:
- Implement MP-safe halt.
- Make the FPU saving code more like Bill's on the i386 MP branch.
  XXX This code will no doubt be revisited again.
- Pass the cpu_info and trapframe to IPI handlers, saving some work
  in the handlers themselves, and also making it possible for the
  "pause" handler to reference register state for DDB.
- Add "machine cpu" to DDB, making it possible to reference other
  CPUs registers (and thus get e.g. a traceback) from whichever
  CPU is actually running the debugger.
- Garbage-collect "machine halt" and "machine reboot" DDB commands.
  They don't have a prayer of working properly in multiprocessor
  kernels, and didn't really work all that well in uniprocessor kernels.
