  Log:
  - Change mi_switch() and sched_switch() to accept an optional thread to
    switch to.  If a non-NULL thread pointer is passed in, then the CPU will
    switch to that thread directly rather than calling choosethread() to pick
    a thread to choose to.
  - Make sched_switch() aware of idle threads and know to do
    TD_SET_CAN_RUN() instead of sticking them on the run queue rather than
    requiring all callers of mi_switch() to know to do this if they can be
    called from an idlethread.
  - Move constants for arguments to mi_switch() and thread_single() out of
    the middle of the function prototypes and up above into their own
    section.
