Try to address bug report from bcallah@openbsd.org re overflow

If max_kbps was wrong for some reason the percentage is obviously wrong
and the string that I put together in display_net() grew large - perhaps
too large, I'm not sure.  I haven't been able to make this happen exactly
as described but I've tried to address any possible issue there by:

  1. increasing the size of the buffers and being more paranoid
  2. explicitly noticing if percent > 100 and display something more
     sensible than "1023191%"; instead now I say "> 100%(!)"

That way you can at least know that osdhud's idea of the max link speed
is wrong a little more explicitly.

Also, death to bzero/bcopy.  Clean up some macros.
