Restrict linger values to a maximum of 32767

* BSD stores linger values in a signed short at the OS level, and as such
  any value over 32767 will wrap around.  This still allows for linger
  setting of just over 9 hours, which seems more than sufficient.

  Making this change rather than making the limit OS dependent keeps
  complexity low and behaviour consistent across all OS within Java.
  Absent a use case for linger times over 9 hours, this seems like the
  best trade off.
