dataplane: add Linux AIO request queue

The IOQueue has a pool of iocb structs and a function to add new
read/write requests.  Multiple requests can be added before calling the
submit function to actually tell the host kernel to begin I/O.  This
allows callers to batch requests and submit them in one go.

The actual I/O is performed using Linux AIO.
