We don't need any of the information in there in the caller, and
this makes it harder to abuse as we don't require the caller to
have memset() the struct first.

- Don't use polled IO for the io_uring-test, that'll fail if the
fs/device doesn't suppor it
- copy read-in was broken for io_uring-cp

- Fixed buffers are now available through io_uring_register()
- Various thread/wq options are now dead and automatic instead
- sqe->index is now sqe->buf_index
- Fixed buffers require flag, not separate opcode

- io_uring_sqe added an index field, for fixed buffer locations
- io_uring_setup(2) system call added a 'nr_iovecs' field

No point in keeping these separate.

Don't rely on this for anything, it's just a test case / demo.

This is cleaner than having the app juggle an SQ and CQ ring,
just wrap them in struct io_uring and have the API always take
that. This means the app doesn't need to worry about the different
types of rings, and that we only need to pass in one argument
for setup/teardown.
