    DEVFS - Fix asynchronous race on reprobe, remove devfs_msg id, cleanup
    
    * The synchronous DISK_DISK_REPROBE and DISK_SLICE_REPROBE messages
      return while make_dev devices are still queued to devfs.  Add
      a call to devfs_config() to wait for the creation of those devices
      to finish before returning.
    
      This fixes numerous problems with shell scripts which fdisk + disklabel +
      newfs in a batch.
    
    * Remove devfs_msg->id, also fixing an issue where the id was retrieves
      after the message is freed.  Async entry points now return void instead
      of the id.
    
    * Adjust devfs_msg_send() to execute the message directly if the calling
      thread is the devfs message thread.  This is not strictly needed right
      now but may be used in the future.
    
    * General cleanup.
