Add io_uring interfaces
Provide a low-level interface to operating the new io_uring interface.

This is an unsafe interface with the basic operations of setting up the
ring, adding to it, removing from it, and polling it.

This will be followed by a safe interface layer on top of this code,
then by additions to the asynchronous executor that allow for
asynchronously doing multiple operations to files from one context.
