Refactor the I/O driver, extracting slab to `tokio::util`. (#1792)

The I/O driver is made private and moved to `tokio::io::driver`. `Registration` is
moved to `tokio::io::Registration` and `PollEvented` is moved to `tokio::io::PollEvented`.

Additionally, the concurrent slab used by the I/O driver is cleaned up and extracted to
`tokio::util::slab`, allowing it to eventually be used by other types.
