    systat - Refactor memory displays for systat -vm
    
    * Report paging and swap activity in bytes and I/Os instead of pages and
      I/Os (I/Os usually matched pages).
    
    * Report zfod and cow in bytes instead of pages.
    
    * Replace the REAL and VIRTUAL section with something that makes a bit
      more sense.
    
      Report active memory (this is just active pages), kernel memory
      (currently just wired but we can add more stuff later), Free
      (inactive + cache + free is considered free/freeable memory), and
      total system memory as reported at boot time.
    
      Report total RSS - basically how many pages the system is mapping to
      user processes.  Due to sharing this can be a large value.
    
      Do not try to report aggregate VSZ as there's no point in doing so
      any more.
    
      Reported swap usage on the main -vm display as well as total swap
      allocated.
    
    * Fix display bug in systat -sw display.
    
    * Add "nvme" device type match for the disk display.
