    kernel - Fix vm.swap_size sysctl
    
    * vm.swap_size was improperly reporting the amount of free
      swap space rather than the amount of swap space configured.
    
    * Add vm.swap_free to report the amount of free swap space.
    
    * Does not affect pstat or libkvm which use the vm.swap_info_array
      sysctl.
