This is a huge change that gets beos building again. Essentially it

- tidies up some of the formatting
- gets us working with mod_status
- uses the newer naming I've used in the headers to try and be more obvious
- uses a UDP socket for telling the server when to stop/restart.  This isn't
  perfect but as pre-BONE we don't have the ability to select on a pipe this
  seemed like the next best option.  This seems to work well for stopping,
  but so far restarts don't.  This will need some more security adding to it
  I think.

If I ever wanted a lesson in not keeping something on my HDD too long before
committing this update has been it.  Really should try and keep up a bit more :)
