REVISION SUMMARY
  Current storage format for the so_options is short and we are already have 16 options defined, which makes it impossible to add new and experimental options. There is very little sense to save 2 bytes of memory per socket in 2016, hence this change.

TEST PLAN
  I've run world and kernel (GENERIC) twice one with this change and one without. No errors or new warnings, so it looks good.

REPOSITORY
  rS FreeBSD src repository
