Merge #872

872: Change sys::aio::lio_listio to sys::aio::LioCb::listio r=asomers a=asomers

The new LioCb structure allows us to control the exact arguments passed
to lio_listio, guaranteeing that each call gets a unique storage
location for the list argument.  This prevents clients from misusing
lio_listio in a way that causes events to get dropped from a kqueue

Fixes #870
